so if you will find a self replicating watch (made from organic components)on another planet. and you will not see any designer. you will conclude design in this case?
No, I will not be able to reach any conclusion about the existence of a designer. Your problem is the same as our colleague Dmmsdale is having. You want to eliminate the possibility of functional complexity arising by naturalistic processes a priori and you can't do it.

so a watch can evolve by a natural process without any designer? ok, in this case i realy have nothing to say. if i will see a watch on another planet i will conclude adesign.

If I found a self-replicating organism on a distant planet which somehow indicated the time I might not be able to tell whether it was designed or the result of natural processes. Period.

xianghua,

I think we will need to draw this to a close. I was looking for dialogue. What I get from you is the refusal to answer my questions, refusal to look at my links, misunderstanding of what I say, and endless repeats of the same things that had already been answered. I find it very frustrating. All this proves is that it is difficult to nail jello to the wall. Care to actually stand for something?

lets focus here. lets say for the sake of the a rgument that the earth is indeed old. the main point is not the age of the earth but what is the best model we have.
No deal. You cannot simply say the earth may be billions of years old, and that all life began 6000 years ago and call that science. The issue is that life is very old. And if you arrange the fossils according to the measured age of the fossils, we see a clear progression of life. Early Precambrian life began about 4 billion years ago and was always single celled. Later, multi-celled life appeared, and by the Cambrian period (starting at 540 million years ago) many simple multi-celled life forms appeared. These forms changed as the years went on, finally resulting in vertebrates walking on the land about 380 million years ago. Fossils continued to progress into reptiles and mammal-like reptiles and then, 80 million years ago, into placental mammals. Only as we get to the most recent layers do we find modern mammal species. All of that is totally consistent with evolution. None of that is consistent with life being created 6000 years ago. If you want to propose some idea between the two that you think is compatible with the fossil record, bring it on. But you refuse to state what you believe, and refuse to say whether life progressed as indicated in the fossil record.

You may think that means you win. No, it doesn't. It just proves it is possible to say words that evade the questions. It just proves that you cannot nail jello to the wall.


and i already showed why any fossils series cant be evidence for evolution. as any series of vehicles cant be eviidence for a common de scent.
You did no such thing. The fossil record is totally incompatible with young earth creationism. Progressive creationism consisting of millions of creations over billions of years can be made compatible with the fossil record, but that fails on other grounds. You apparently try to sneak young earth creation in the backdoor. You have not given the slightest evidence for your apparent young earth creationism that apparently has life created perhaps 6000 years ago, but you refuse to tell us when you think it happened.

When do you think the first life was on earth?

not true. first: we have seen that some fossils are in the wrong order too. and you still believe that they show evolution even with this wrong order.
You have shown no fossils in the wrong order. You have shown that some descendents of some species might still exist after a new species has come around, but this is not the wrong order.

no. the modern horse arent necessarily more advance then the old one. so its just series of similar creatures. and you also doesnt mention that they all may belong to the same family- so they are basically the same creature. so its not evolution but a variation.

Why is it that, 50 million years ago, we find hyracotherium, and none of the other horses?

Why is it that 40 million years ago, we start to see Mesohippus, but none of the more modern horses?

Why is it that, as time progresses, the horses look more and more like modern horses?

You have no answer for any of that, do you? You will whistle in the wind and pretend nobody asked, yes?
about the layers: if when the earth was formed the upper layer was cooler then the bottom layers (again: if we assume the acceleration is true), then it may explain this evidence. in this case the upper (and suppose younger)layers just covered the bottom (suppose older) layers. just maybe.
Sorry, we are talking about fossil bearing layers. The earth was never plasma, and it certainly was not plasma when there were animals on earth. Try again.

lets focus here. lets say for the sake of the a rgument that the earth is indeed old. the main point is not the age of the earth but what is the best model we have.




i never said that you said that its the only evidence. we just discuss one of the suppose 29 evidences for a common descent. so you choose the fossils. and i already showed why any fossils series cant be evidence for evolution. as any series of vehicles cant be eviidence for a common de scent.




not true. first: we have seen that some fossils are in the wrong order too. and you still believe that they show evolution even with this wrong order. secondly: we can find a non- arbitrary hierarchy in design objects too. but its still cant be evidence for evolution. so even a non-arbitrary hierarchy isnt evidence for evolution.





no. the modern horse arent necessarily more advance then the old one. so its just series of similar creatures. and you also doesnt mention that they all may belong to the same family- so they are basically the same creature. so its not evolution but a variation.







not at all. actually some creatures cant survive without them. so its a good evidence that ervs always was an integral part of the genome. otherwise how you can explain that the creature survived before he get the viral infection? we also know that retroviruses cant survive without the host (again: how the virus survived in the first place if it need a host?). so its another evidence that viruses created from the host parts and not the opposite.

about the layers: if when the earth was formed the upper layer was cooler then the bottom layers (again: if we assume the acceleration is true), then it may explain this evidence. in this case the upper (and suppose younger)layers just covered the bottom (suppose older) layers. just maybe.






no. the DNA they found is almost the same like others species of this family (as far as i aware about). so it cant be a contamination. if its was a real contamination we should predict to find a different sequence that match to other family.​

this is a reply to doubtingmerle's post 469, not to astrophile's post 465.​


again: if all those atoms was effected by the plasma state, then they will be in a good correlation. we only need about several minutes of plasma temp to make a 1000 years rock to look like a bilion years old.

The rocks that are dated by radiometric dating have never been subjected to plasma temperatures, and certainly not to the megakelvin temperatures that would be required to strip 187-Re atoms of all of their electrons. Also your statement is not even true. You quoted from Wikipedia,
Rhenium-osmium dating - Wikipedia

"This normally occurs with a half-life of 41.6 × 109 y,[1] but studies using fully ionised 187Re atoms have found that this can decrease to only 33 y"

In other words, it would take about 290 days (33 years/41.6) of decay with a half-life of 33 years to yield a rhenium-osmium ratio appropriate to an age of a billion years, not only 'several minutes'.

ok. lets say that the earth is indeed 4.5 bilion years old for the discussion.



Fossils continued to progress into reptiles and mammal-like reptiles and then, 80 million years ago, into placental mammals. Only as we get to the most recent layers do we find modern mammal species. All of that is totally consistent with evolution. None of that is consistent with life being created 6000 years ago. If you want to propose some idea between the two that you think is compatible with the fossil record, bring it on. But you refuse to state what you believe, and refuse to say whether life progressed as indicated in the fossil record.


first; we dont see a real progression (apart for the first step: single cell organism that can be explain by the huge population of bacteria). but we do see different groups in a different time. again: we see this also in a human-mamde objects like cars and airplanes. they both aoppeared in a different time. so order in the fossils record cant prove any evolution.


You have not given the slightest evidence for your apparent young earth creationism that apparently has life created perhaps 6000 years ago


not true. i gave you a DNA from a suppose 20 my fossil. and you said that: "

"Rather they state that they believe this DNA does not survive more than 17500 years in the situations they know, and that they think they will make better progress looking at ancient proteins. They are not saying that science has proven this is the limit. "-


true. but for now this is what the evidences and experiments show about DNA. so we are going by the evidences we have and not by the evidence we dont have. so for now: you cant explain how this DNA survive. but a recent creation explain it fine.

you also said:

"And again, the partial DNA that is being found in ancient fossils is commonly thought to be later contamination. You have not proven it really was part of the original fossil."

and again they check for contamination and said that its very unlikely.



You have shown no fossils in the wrong order. You have shown that some descendents of some species might still exist after a new species has come around, but this is not the wrong order.

not true. the fossil is more advance then the fossils that appear after it. so we have this order of --> fish-->a tetrapod-->a missing link between a fish and a tetrapod. instead of fish-->a missing link-->a tetrpod. a fossil in the wrong place.


Why is it that, as time progresses, the horses look more and more like modern horses?

You have no answer for any of that, do you? You will whistle in the wind and pretend nobody asked, yes?


again: even if they evolved from each other its still may be the same creature (its mean no evolution of a new kind). so what is your point?


Sorry, we are talking about fossil bearing layers. The earth was never plasma, and it certainly was not plasma when there were animals on earth. Try again.

if the plasma state happened before the earth was formed (something that we have evidence for it)then it may by possible. maybe not. we just dont know for sure.

Much of the commonality of the genes is compelling but the divergence is significant as well:

In weighing alternative hypotheses of FOXP2 or any gene's potential involvement in the evolution of form (or neural circuitry), we should ask the following questions. (i) Is the gene product used in multiple tissues? (ii) Are mutations in the coding sequence known or likely to be pleiotropic? (iii) Does the locus contain multiple cis-regulatory elements?

64,65]. Patients with the FOXP2 mutation do have multiple neural deficits [66]. And, because FOXP2 is expressed in different organs and different regions of the brain, it is certain to possess multiple regulatory elements. Furthermore, it is an enormous, complex locus, spanning some 267 kb. Based upon a simple average base pair divergence of 1.2%, there should be over 2,000 nucleotide differences between chimps and humans in this span. Because there is much more potential for functional divergence in non-coding sequences, there is no specific reason to favor coding sequence divergence over regulatory sequence divergence at FOXP2. (Evolution at Two Levels: On Genes and Form. PLOS)​

Two problems here, one is mutations in this regulatory gene result in 'multiple neural deficits' and 'there is no specific reason to favor coding sequence divergence'. Specifically known effects of changes and assumed changes known from comparative genomics. There is no known mechanism for facilitating this change and yet we are supposed to assume it's the result of some serendipitous mutation.
Are genes related to brain development different between humans and chimps, yes or no? When that answer is yes, that means that there are genetic variants that can result in higher levels of intelligence by default. The variation in species, and the subtle to extreme differences they afford, make every living thing on this planet inherently contradict your claim that no mutation or group of mutations could have a significant beneficial impact on intelligence. We can literally quantify many of the genetic differences between humans and other species that makes us more intelligent than they are. Heck, what do you make of a genus born to parents with average intelligence, hmm? The variation within our own species in terms of intelligence defeats your claim that mutations can never benefit intelligence. We just give more attention to the mutations that do bad than those that do good. What about the mutation in an extended family in Italy that makes them practically immune to cholesterol build up and heart disease? A member of that family in her 70s had the arteries of someone in their 20s. Is that not beneficial to you?




Yes, I'm aware of that and gene expression has a lot of complications that don't require dramatically different sequences. Gross structural changes in protein products seem a little high when it gets up to 20%.

Taken together, gross structural changes affecting gene products are far more common than previously estimated 20.3% of the PTR22 proteins. (DNA sequence and comparative analysis of chimpanzee chromosome 22, Nature 2004)​

Yes, so why couldn't this satisfy you claim for the degree of physical difference needed to produce higher intelligence? Slight changes in the genetic code can have drastic consequences, and they aren't inherently negative.​




That looks like an amino acid substitution, changes can be equivocated with genetic mutations so I'm not sure if you have a point here or not.
-_- what do you think would have caused the amino acid substitution to run in families aside from genetic mutation? It can't just be environment, because not everyone with this trait lives similarly.



I'm not sure how you think this is a point of contention, I certainly never meant it that way. For me, Darwinian evolution has proven itself to be a pretty interesting unified theory. All theories are unified theories since they are an attempt to unify the facts. I watched a lot of House, I always thought how they did differential diagnosis was a perfect example of how you get a working theory. House would write all the symptoms on the white board and when they had a theory that explained them all they usually had a diagnosis. My thing has always been philosophy and while the scientific literature is compelling I always looked at this somewhat philosophically. When I talk about a unified theory on this scale I'm talking about the search for a unified theory of physics for instance, String Theory. Charles Darwin was confronted with his theory being metaphysics and he simply responded I don't know much about metaphysics. I'm paraphrasing obviously but a unified theory in an inductive system would be a massive undertaking. Physics never got theirs done, Biology I think it's safe to say, did with the establishment of the DNA double helix. That is not to disparage chromosome theory or the various others.
Definitions of metaphysics:
the branch of philosophy that deals with the first principles of things, including abstract concepts such as being, knowing, substance, cause, identity, time, and space.
  • abstract theory or talk with no basis in reality.
The theory of evolution was derived originally by observations Darwin made about wildlife, that is its initial basis in reality. We observe changes in the trends of traits in populations over time, that is the basis. If a mountain has consistently grown 4 inches taller every year for the past 40 years, is it truly inconceivable to conclude that the year prior to the first measured year, it probably grew 4 inches?

Needing less sleep is one thing, a bigger and better brain is another one. Darwinians have a very serious problem and always seem to get a pass. Mutations in these very sensitive genes result in disease and disorder on an epic level. Given the fact that the three fold expansion of the human brain from that of apes happened virtually over night is cause for skepticism.
A bigger, better brain could be the result of just one mutation, you know. The genes for human brain development and for, say, the brain development of a mouse, are almost exactly the same. Much more similar between humans and other apes. And other apes aren't stupid, if you speak sign language, you can have conversations with them, they're about as smart as 4-8 year old human children. Structurally, the brain of a chimp is almost exactly like a smaller version of a human brain. It doesn't take many mutations to change the size of an organ. Consider this scenario: what if the norm in the past was a genotype that would be associated with mental defect in our species today, and what was a rare mutation in the past is what the modern common genotype is derived from?



I'm hardly obsessed, this is a pass time for me. What I keep running into is the fact that highly deleterious effects arise from mutations in brain related genes and there are very few beneficial effects.
Doesn't need to be many for evolution to act upon.

I couldn't agree more that the death of the unborn would result from deleterious mutations but when you compare that to 60 de novo genes required and a massive overhaul of highly conserved genes you have a serious problem.
Shockingly, a lot of the genes associated with brain function are not highly conserved, mostly just the genes that direct the brain to form at all, and where it should go. Why do you think mental disorders are so common in our species? Almost 20% of humanity is mentally defective in one way or another. Here's the thing: as long as it doesn't stop you from reproducing, it can be passed on to the next generation anyways. Also, you say "de novo" as if we don't experience genetic mutations all the time. Every person is born with between 40-60 de novo genes, so why are you acting like 60 is a problem? That's not very many mutations.


Ok, lets assume a beneficial effect for a minute just for the sake of argument.

The number of loci in a vertebrate species has been estimated at about 40,000. 'Good' species, even when closely related, may differ at several thousand loci, even if the differences at most of them are very slight. But it takes as many deaths, or their equivalents, to replace a gene by one producing a barely distinguishable phenotype as by one producing a very different one. If two species differ at 1000 loci, and the mean rate of gene substitution, as has been suggested, is one per 300 generations, it will take 300,000 generations to generate an interspecific difference. (Haldane, J.B.S., "The Cost of Natural Selection)​

Thats assuming a beneficial effect, this is never as cut and dried as it seems.
-_- mutations are mistakes that life has to deal with. Occassionally, those mistakes result in something good, like how sticky notes and silly putty and puffed chips are the results of errors. Most errors don't result in anything good, that's fine and dandy, the fact that any do gives natural selection something to act on.

Furthermore, your own quote hurts your point that "less sleep is one thing, but increased intelligence is another". This is because the deaths that come with producing a drastic change are EQUIVALENT to those producing a minor one. Of the approximately 2 million different egg cells in my body when I was born, how many do you think would even have a chance of becoming a realized human? Well, the world record of births from a single mother that had kids live past infancy is 67 (she gave birth to 69, and two died in infancy). That means the human female with the highest evolutionary fitness only had 0.00335% of her egg cells succeed at most (I highly doubt that every child born as a twin, triplet, and quadruplet was fraternal, so that percentage is likely lower). And let's not even get started on how many sperm cells men produce compared to the number that fertilize eggs. So, there's the necessary deaths for you. Who said they had to happen after fertilization, when sex cells can genetically fail without fertilization?

first; we dont see a real progression (apart for the first step: single cell organism that can be explain by the huge population of bacteria). but we do see different groups in a different time.
That is because you are not looking. Creationists before Darwin knew there was a progression in the layers before Darwin, and that life got to be more like modern life as time progressed.

All I am asking is that you start by recognizing what creationists in the 19th century knew before Darwin, that life had been around a long time, that it started very strange, and got more and more like modern life over a long period of time. Is that asking too much?

For instance, we can see how the mammal jaw evolved with time. You will find nothing remotely close to the mammal jaw and ear before 300 million years ago. Then Synapsids appeared with jaw bones that had a bulge where the mammalian jaw joint would later appear. Later animals had another bulge leading toward the ear drum. Later animals had jaws even closer to the mammal, while still using the distinct reptile jaw joint. By about 230 million years ago, animals appeared that had two jaw joints, the reptile and mammal jaw joint. The bones that formed the reptile jaw joint then freed up in later animals and began to be used to transmit sounds to the ear drum. By 200 million years ago, animals have these back bones completely separate from the jaw bone and they form the three little bones in the ear. By 80 million years ago, we see placenta mammals. When you lay the fossils beside each other, you can see the step by step progression from reptile jaw to mammal jaw and ear. See Evolution of mammalian auditory ossicles - Wikipedia .
Now how do you explain any of that? Why were there no mammals before this strange series of mammal like reptiles? Why do we find only amphibians and reptiles for tens of millions of years, then a long string of animals with jaws and ear bones progressively like mammals, then mammals? Why that order? You have no explanation, do you?


not true. i gave you a DNA from a suppose 20 my fossil. and you said that: "

"Rather they state that they believe this DNA does not survive more than 17500 years in the situations they know, and that they think they will make better progress looking at ancient proteins. They are not saying that science has proven this is the limit. "-


true. but for now this is what the evidences and experiments show about DNA. so we are going by the evidences we have and not by the evidence we dont have. so for now: you cant explain how this DNA survive. but a recent creation explain it fine.
No, that is not what the evidence says. The scientists who wrote that study only say that is what they believe. They do not say they know this to be true. The fact that some scientists believe they will not find DNA older than 17,000 years does not prove it is true.

Compare that with macro-evolution, which has been shown to be overwhelming true by many studies that were reviewed by many scientists.

Compare that with radiometric dating that is confirmed in hundreds of articles. You ignore them all, and repeat over and over that one article that does not even say what you claim. Sad, that.
not true. the fossil is more advance then the fossils that appear after it. so we have this order of --> fish-->a tetrapod-->a missing link between a fish and a tetrapod. instead of fish-->a missing link-->a tetrpod. a fossil in the wrong place.
Excuse me, but I gave you three possible explanations and you ignored all three. Why should I repeat it over and over to you?
again: even if they evolved from each other its still may be the same creature (its mean no evolution of a new kind). so what is your point?
My point is that Hyracotherium lived before Mesohippus which lived before zebras. My point is that most likely zebras evolved from Hyracatherium or close relatives to the Hyracatherium.

Do you or do you not think that zebra evolved from Hyracotherium. You refuse to answer.

Do you or do you not think that Hyracatherium lived 50 million years ago, but no zebras? You refuse to answer.

Do you or do you not think that animals like Mesohippus and Merychippus appeared sequentially in the fossil record, looking more and more like the horse and zebra as time progressed? You refuse to answer.

Do you or do you no believe animals lived more than one million years ago? You refuse to answer.

You have no position. It appears you may be claiming all animals were created over a six day period 6000 years ago, but you refuse to tell us if that is your position. You refuse to answer question. You have no position.


if the plasma state happened before the earth was formed (something that we have evidence for it)then it may by possible. maybe not. we just dont know for sure.
This has been explained to you before, and you simply ignored our responses. If we explained it again, you would ignore us again, yes?

I stepped on a chalked "fossilstone" in Åland when I played in a small flowing stream as a kid. I took it with me home. One can see seashells that have left an imprint in the chalkstone. Where have You hiked Herman Hedning? If You like hiking You should dress warmly and sleep outdoors before the mosquitos come because now spring has arrived and the stars are so beautiful still. Get Yourself an adventure but not in Göteborg city, perhaps in the forest or a summercottage balcony.

If I found a self-replicating organism on a distant planet which somehow indicated the time I might not be able to tell whether it was designed or the result of natural processes. Period.

ok. i will focus here in 2 claims at time. in this way it will be easy to show you what is wrong.


now you gave the jaw evolution. i do think it doesnt prove any evolution because in this case they are clearly different creatures. so under the design model they not evolved from each other. i guess you believe that they are indeed evolved from each other. right? but again: even in this case we cant conclude any evolution. we can find hierarchy in vehicles too. but again; it doesnt prove any evolution.


"Excuse me, but I gave you three possible explanations and you ignored all three. Why should I repeat it over and over to you?"-


but you said that "You have shown no fossils in the wrong order". so according to you we can never find any wrong place fossil. even if we will find a human fossil with a dino one. so the claim that we do find order in the fossil record and in the same time we ignore all the rest its just a joke.

Xianghua,

Do you or do you not think there was a time millions of years ago that Hyracatherium lived, but no zebras yet? You refuse to answer.

Do you or do you not think that animals like Mesohippus and Merychippus appeared sequentially in the fossil record after the Hyracatherium, looking more and more like the horse and zebra as time progressed? You refuse to answer.

Do you or do you not believe animals have been living on earth for over a million years? You refuse to answer.

Do you or do you not think that a series of mammal like reptiles lived on earth before the first placental mammal. You will refuse to answer, yes?

Do you or do you not agree that the fossil record shows ear bones and jaws getting progressively close to the mammal pattern with time? You will refuse to answer, yes?

You have no position. All you do is evade. All this proves is that it is impossible to nail jello to the wall.


now you gave the jaw evolution. i do think it doesnt prove any evolution because in this case they are clearly different creatures. so under the design model they not evolved from each other.
You are merely assuming the case in point. How do you know that various Therapsids did not evolve from each other?

Here is a list of the hundreds of Theapsid genera in the fossil record.
List of therapsids - Wikipedia. These all have jaws intermediate between reptiles and mammals. There were thousands of reptiles before these fossils were made, but no modern placental mammals until afterwards. You have no explanation, do you?

but you said that "You have shown no fossils in the wrong order". so according to you we can never find any wrong place fossil. even if we will find a human fossil with a dino one. so the claim that we do find order in the fossil record and in the same time we ignore all the rest its just a joke.
Uh, no, I never said it would be impossible for a fossil to be in the wrong place. Find a human in the Cambrian, and that upsets the whole geologic column. But your job is to find something like that, not merely argue about what happens if we find such a fossil.

Are genes related to brain development different between humans and chimps, yes or no? When that answer is yes, that means that there are genetic variants that can result in higher levels of intelligence by default.

Those differences are divergence and by their very nature demand a burden of proof, not just to the effect but the cause. Mutations are the worst possible explanation. We know many things about the effects of mutations on brain related genes and random copy errors don't result in bigger and better brains, they result in disease and disorder. Your not going to get around that one.

The variation in species, and the subtle to extreme differences they afford, make every living thing on this planet inherently contradict your claim that no mutation or group of mutations could have a significant beneficial impact on intelligence.

That's the problem, the equivocation of variation with mutations. I'm well aware that genes are sometimes modified, sometimes by still unknown molecular mechanisms. My point is simply that mutations in brain related genes yield disease and disorder like cancer, tumors, Fragile X syndrome and a host of neurological disorders.

We can literally quantify many of the genetic differences between humans and other species that makes us more intelligent than they are. Heck, what do you make of a genus born to parents with average intelligence, hmm? The variation within our own species in terms of intelligence defeats your claim that mutations can never benefit intelligence.

So why don't we have examples? Mutations in brain related genes on an evolutionary scale effecting brain related genes. The brain of the hominids has to nearly triple in size and we are learning that this is directly linked to more then gene expression, brain related genes have to be profoundly changed. Mutations, is the worst possible example of a possible cause due to functional constraints and especially the known deleterious effects.

We just give more attention to the mutations that do bad than those that do good. What about the mutation in an extended family in Italy that makes them practically immune to cholesterol build up and heart disease? A member of that family in her 70s had the arteries of someone in their 20s. Is that not beneficial to you?

That's a great example, a little less specific then I like but perfectly applicable. I know that adaptive evolution happens with regards to cholesterol and brain related genes are different things. Surely you see this.

Yes, so why couldn't this satisfy you claim for the degree of physical difference needed to produce higher intelligence? Slight changes in the genetic code can have drastic consequences, and they aren't inherently negative.

There is an evident and obvious reason why this is a problem, call it skepticism if you will. They are either deleterious in their effects or do nothing at all. I'm talking about HAR1f and other vitally important genes changing over night about two million years ago. The question has to be, how. If you say mutations your obviously wrong.


-_- what do you think would have caused the amino acid substitution to run in families aside from genetic mutation? It can't just be environment, because not everyone with this trait lives similarly.

It's anecdotal, that's the problem.

Definitions of metaphysics:
the branch of philosophy that deals with the first principles of things, including abstract concepts such as being, knowing, substance, cause, identity, time, and space.
  • abstract theory or talk with no basis in reality.
The first cause of life has no basis in reality? Is that really your argument in a topic related to the ongoing controversy between evolution and creation? Science isn't allowed to make an inference with regards to a miracle but that doesn't mean there is no such thing in reality, especially with regards to the origin of life.
The theory of evolution was derived originally by observations Darwin made about wildlife, that is its initial basis in reality. We observe changes in the trends of traits in populations over time, that is the basis. If a mountain has consistently grown 4 inches taller every year for the past 40 years, is it truly inconceivable to conclude that the year prior to the first measured year, it probably grew 4 inches?

So we go from Charles Darwin making inference about Orchids and pigeons to the development of the human brain from that of apes? Really? Then we are going to somehow relate that to mountains. Things changing and things changing on a massive scale are obviously two different things, certainly geology and biology are two different things.

A bigger, better brain could be the result of just one mutation, you know. The genes for human brain development and for, say, the brain development of a mouse, are almost exactly the same.

That's just not true:

Bruce Lahn, the senior author at the Howard Hughes Medical Center at the University of Chicago and colleagues have suggested that there are specific genes that control the size of the human brain. These genes continue to play a role in brain evolution, implying that the brain is continuing to evolve. The study began with the researchers assessing 214 genes that are involved in brain development. These genes were obtained from humans, macaques, rats and mice. Lahn and the other researchers noted points in the DNA sequences that caused protein alterations. These DNA changes were then scaled to the evolutionary time that it took for those changes to occur. The data showed the genes in the human brain evolved much faster than those of the other species. Once this genomic evidence was acquired, Lahn and his team decided to find the specific gene or genes that allowed for or even controlled this rapid evolution. Two genes were found to control the size of the human brain as it develops. (Evolution of the brain Wikipedia)​

Much more similar between humans and other apes. And other apes aren't stupid, if you speak sign language, you can have conversations with them, they're about as smart as 4-8 year old human children. Structurally, the brain of a chimp is almost exactly like a smaller version of a human brain. It doesn't take many mutations to change the size of an organ. Consider this scenario: what if the norm in the past was a genotype that would be associated with mental defect in our species today, and what was a rare mutation in the past is what the modern common genotype is derived from?

Are you really sure about that?

Doesn't need to be many for evolution to act upon.

Darwin discussed what he called the 'bane of horticulture', this was infertility. Haldane in 'The Cost of Natural Selection indicated "genetic deaths," which is either deaths or it's equivalents in reduced fertility. He said that it would take 300 generations for a beneficial mutation to become fixed with 1667 accrued in 10 million years.

Like Darwin, he used artificial selection to illustrate what would have had to happen in natural settings:

"especially in slowly breeding animals such as cattle, one cannot cull even half the females, even though only one in a hundred of them combines the various qualities desired." (Haldane, The Cost of Natural Selection)​

For us to have evolved from apes it would have required an accelerated evolution of brain related genes. The evolution of the human brain would have had to start it's accelerated evolution on a molecular basis some 2 million years ago and within Homo Erectus (considered human by most creationists) would have had a brain size twice that of the Austropihicene and early Hominids:

Early Ancestors:

A. Afarensis with a cranial capacity of ~430cc lived about 3.5 mya.
A. Africanus with a cranial capacity of ~480cc lived 3.3-2.5 mya.
P. aethiopicus with a cranial capacity of 410cc lived about 2.5 mya.
P. boisei with a cranial capacity of 490-530cc lived between 2.3-1.2 mya.
OH 5 'Zinj" with a cranial capacity of 530cc lived 1.8 mya.
KNM ER 406 with a cranial capacity of 510cc lived 1.7 million years ago.​

The evidence is mounting and gene expression isn't an explanation. Mutations is even worse and there is really no clue as to a molecular mechanism.

Shockingly, a lot of the genes associated with brain function are not highly conserved, mostly just the genes that direct the brain to form at all, and where it should go. Why do you think mental disorders are so common in our species? Almost 20% of humanity is mentally defective in one way or another. Here's the thing: as long as it doesn't stop you from reproducing, it can be passed on to the next generation anyways. Also, you say "de novo" as if we don't experience genetic mutations all the time. Every person is born with between 40-60 de novo genes, so why are you acting like 60 is a problem? That's not very many mutations.

Hang on! Every person is born with 40-60 de novo genes? 40 to 60 brand new genes? On average humans across the spectrum diverge by one tenth of one percent and your telling me brand new genes are emerging every generation? That's completely and patently absurd.

-_- mutations are mistakes that life has to deal with. Occassionally, those mistakes result in something good, like how sticky notes and silly putty and puffed chips are the results of errors. Most errors don't result in anything good, that's fine and dandy, the fact that any do gives natural selection something to act on.

The rarest of effects from mutations are beneficial, with the exception of those adaptive on an evolutionary scale.

Furthermore, your own quote hurts your point that "less sleep is one thing, but increased intelligence is another". This is because the deaths that come with producing a drastic change are EQUIVALENT to those producing a minor one. Of the approximately 2 million different egg cells in my body when I was born, how many do you think would even have a chance of becoming a realized human? Well, the world record of births from a single mother that had kids live past infancy is 67 (she gave birth to 69, and two died in infancy). That means the human female with the highest evolutionary fitness only had 0.00335% of her egg cells succeed at most (I highly doubt that every child born as a twin, triplet, and quadruplet was fraternal, so that percentage is likely lower). And let's not even get started on how many sperm cells men produce compared to the number that fertilize eggs. So, there's the necessary deaths for you. Who said they had to happen after fertilization, when sex cells can genetically fail without fertilization?

The diversity of the earliest stages of development, here illustrated strictly within the vertebrates, provides one of the strongest challenges to the neo-Darwinian conception of homology and macroevolution. Given the hierarchical, step-wise logic or "architecture" of animal development, early stages such as cleavage and gastrulation lay the groundwork for all that follows. Body plan structures in the adult, for example, trace their cellular lineage to these early stages. Thus, if macroevolution is going to occur, it must begin in early development. Yet it is precisely here, in early development, that organisms are least tolerant of mutations. Furthermore, the adult homologies shared by these vertebrates commence at remarkably different points (e.g., cleavage patterns). How then did these different starting points evolve from a common ancestor? (Homology, a Concept in Crisis)
That is the last place you would expect a mutation to have a beneficial effect but that is exactly where it would have to occur. That's not making a lot of sense to me.

so a watch can evolve by a natural process without any designer?

That is not at all what the post that you are replying to, said.
Not even remotely.

Try some intellectual honesty while engaging in discussion.

first; we dont see a real progression (apart for the first step: single cell organism that can be explain by the huge population of bacteria)
Except that we do.

Here's an easy example for whale evolution:

upload_2017-4-12_13-43-51.png


As time progresses, the body of these specimen "turn" increasingly more aquatic (loss of limbs over time and the formation of more fin-like structures as replacement).

But the clearest progressive change here, is, off course, the move of the nostrils from the front of the face (the nose) all the way back to the top of the head.

If whales used to be land mammals, then this is exactly the type of thing we'ld expect to find in the fossil record. The oldest fossils should have nostrils at the front of the face, just like all other land mammals.

As we progress to the present day and age, we should find skulls where this blowhole moves from the front of the face all the way back to the top of the skull.

Lo and behold, that exactly what we find in the fossil record.
Some of these fossils have even been found by prediction.

As in: "we need to go to this region here, dig down x meters and there we should be able to find a skull of a semi-aquatic mammal with a blowhole half-way between the front of the face and the top of the skull".

And lo and behold, after a year of digging, that is exactly what was found.

we can find hierarchy in vehicles too.

Not a SINGLE productline of humans falls into a nested hierarchy. Not a SINGLE one.
Not even if we limit ourselves to the products of a SINGLE manufacturer.
Not even if we limit ourselves to the products within a single brand of a single manufacturer.

but again; it doesnt prove any evolution.

Fossils don't prove evolution. They merely support it. As in: the fossils we find are consistent with an evolutionary history.

You know what proves evolution (in the sense of common ancestry)? Genetics.

We can compare DNA and determine ancestry. We do it every day in court cases when trying to determine who is the biological father of a contested child.

but you said that "You have shown no fossils in the wrong order". so according to you we can never find any wrong place fossil. even if we will find a human fossil with a dino one.

No, humans and dino's next to eachother would be a real problem for evolution theory.
But we never find such things. Which is not surprising, considering how solid evolution is as an explanatory model for the diversity of life.

so the claim that we do find order in the fossil record and in the same time we ignore all the rest its just a joke.

Nobody on this side of the table is ignoring anything.
You are welcome to point out something that is supposedly ignored, if you think there is.

so if you will find a self replicating watch (made from organic components)on another planet. and you will not see any designer. you will conclude design in this case?
Depends on if the watch can reproduce or has any traits of a living thing, or if there are any natural processes which could produce the watch. If the answer to both is no, then I conclude that the watch MUST be designed by something. Note that by having traits of living organisms, you render your "self-replicating watch" as covered by the theory of evolution, assuming that it's biology is analogous to organisms on our own planet.

However, the watch could still have traits that would make it distinctly designed, such as having no innate mechanism of metabolizing energy, even though symbiosis, which would demand constant intervention to keep it alive. However, these traits notably are not a part of the biology of organisms on our planet.

Do you or do you not agree that the fossil record shows ear bones and jaws getting progressively close to the mammal pattern with time? You will refuse to answer, yes?

yes they do, but they dont prove any evolution. how many times i need to say this?


You have no position. All you do is evade.

yes i have. i said that different creatures arent evolved from each other because we dont have any scientific proof that its possible. another argument against this transition are the ic systems that we can find between the creatures. for instance: the melon organ in whales need at least several parts to be a functional. so it cant evolve stepwise. a motion system need at least several parts to its minimal function. so it cant evolve stepwise and so on.


Here is a list of the hundreds of Theapsid genera in the fossil record.
List of therapsids - Wikipedia. These all have jaws intermediate between reptiles and mammals. There were thousands of reptiles before these fossils were made, but no modern placental mammals until afterwards. You have no explanation, do you?

so what? we can also find such an order in vehicles too: a car--> a fighter jet--> a space shuttle. but again: it doesnt prove any evolution but a design.



Uh, no, I never said it would be impossible for a fossil to be in the wrong place. Find a human in the Cambrian, and that upsets the whole geologic column. But your job is to find something like that, not merely argue about what happens if we find such a fossil.

i already show to you a fossil that is in the wrong place by about 30my. so its like finding an ape fossil that is date about 60my. if this is not a fossil in the wrong place then any fossil cant be in the wrong place. so in this case any claim about a wrong place fossil is meaningless.
