As Noble found out (Neo) Darwinism has lead scientist down the wrong path and what they thought was wrong for 100+ years turned out to be true. Physiology and the revolution in Evolutionary Biology | Voices From Oxford
Actually they don't. Change means to change one thing for another. Alter meant to change soemthing already in existence.
The mutation of an albino did not change something and give it skin, it altered the skin it woudl have gotten without the mutation.
The bottom line is that mutations cannot change a species into a different species.
If you want to use "change" and "alter" the same way fine.
I have not denied anything except mutation are a mechanism for evolution. Do you have any evidence that anything in the paragraph above has resulted in a change of species?
That's fine. Have a nice day. I would like you to provided the evidence that mutations, and take as many as you like, have ever resulted in a change of species. If you can't do that then what you have said is nonsense as far as mutations being a mechanims for evolution is concerned.
You constantly demand evidence and when it is provided you simply ignore it.
You have claimed to know more about biology than our resident evolutionist biology;<<
That is not true. It is anothe example yoou neeing to embellish your remarks hoping they will seem more credible. Hint: It doesns't.
especially when you have no formal education on the subject. <<
One doesn't need a formal education on the subject to understand a few basics. I also have the ability to read and understand what the scientist on the other side say, do you.
Your arrogance astounds me.
Your ability to embellish astounds me.
Hmm. The Johns didn't strike me as this bad at typing, but you might be right...JohnR7, Jazer, Jamin and all of his sock puppets.
I think that depends on your idea of "dramatic". Recognising the importance of neutral evolution was a pretty dramatic change, for example.Yes.
Not as dramatically as when Einstein's Relativity replaced Newton's mechanics, but yes.
This is so clueless I don't even know how to deal with it.Which primate came first? If chimps are our cmmon ancestor, why is our DNA different? Why can't we mate with them and bear offsprsing? Lemers are also primates, why are they not our common ancester?
All primates' DNA is different from all other primates. Otherwise there wouldn't be different primates.Where is your evidence? Why is our DNA different than that of ALL other primates.
HOW?The problem for you is that DNA proves you wrong.
Because you can change something that isn't already in existence?Actually they don't. Change means to change one thing for another. Alter meant to change soemthing already in existence.
Mutations bring about change in a living thing.They do not bring aboaut a change in the species and that is what you and others are trying to use as justification for what you beleive.
>>Evolution is CHANGE. <<
Actually it is more than that. It is a THOERY, that has neve been scientifically proven that requiireds a species change into a different species.
Now unless you understand that then we have nothing more to discuss as your knowledge of the English language is inadequate and there is no way anyone can explain to you how evolution works.
If English was your mother language you would know hot to explain it with some biological evidence. My knowledge of English is at least as good as yours and probably better, and I dont have to be insulting to get my points across like you do.
See if your English is good enough to understand this: Those who feel it necessary to insult those they disagree with is because they do not have the intellecltualy capability to defend their position. They think insults make their opponent look bad, but in fact it makes them look ignorant.
Why do you keep using the word 'alter'? It's like you're afraid to use the word 'change', but 'change' and 'alter' mean the same thing. It's not fooling anyone.
And it is a mechanism for evolution.
Actually it is more than that. It is a THOERY, that has neve been scientifically proven that requiireds a species change into a different species.
Then give me on example of a mutation that caused a species to change into a different species.
OK! now you have defined a difference between change and alter. We can work with that. To alter is to change the details without changing the essesnce To change, in this context, means to change the essence. Fine.
Now that we agree, on the distinction, How does a mutagen tell the difference between a mutation that alters a gene and one that changes a gene? And what prevents the mutagen from making the second kind of mutation?
Selection favors one trait over others in survivability, fertility, or mating opportunity.
Each generation more individual have the selected trait, and less have the unselected traits.
If you have different sub-populations being selected for different traits, then given enough generations, you will end up with different breeds. At this point, they are still all the same species, the same kind.
But this is where those slight difficulties in breeding crop up. Within each sub-population, the same changes accumulate, so they all have the same changed genes, which match up and present no barrier to breeding, but between breeds, different changes accumulate, so it becomes more and more difficult for one breed to breed with a different breed. At some point, the difficulty has become great enough that cross-breeding is impossible. However each breed can still freely breed within itself. The greater group changes from a population of one species, with sub-populations of various breeds to a collection of separate populations that can't crossbreed.
The mechanism that you are looking for, therefore, is the very "change" that you dismiss as impossible without looking at the evidence, or giving a mechanism to explain the "impossibility." I have asked you repeatedly WHY it is impossible, and HOW the mutation is blocked from happening and you have not answered. You have been shown that despite your claim of impossible, the genes are "changed" sometimes, and not simply "altered," and you ignore the news.
The evidence is found in
1) The existence of Ring Species which are transitioning from breeds to separate species. The farther apart the sub-populations are, the less successful cross-breeding is.
2) Hybridization. Mules and hinneys, ligers and tigons should not exist, but the separation of the parent species was never completed.
3) The human genome. We have completely mapped out the human genome and the chimpanzee genome. And we can see how close they are. They are as close as some of the species that can hybridize. We don't know whether or not we can hybridize with chimpanzees because it would be unethical to make the attempt.
This evidence establishes beyond doubt certain lines of descent.
Alone, it is insufficient to establish Universal Common Descent, but when you add in other known genomes, such as dog and rat, and even more distantly similar organisms, and the fossil record it.
Natural selecdtion, which cannot be proven
If evolution was true at least 80% of fossils would be transitional and after 100+ years you have none.
He said mutations ALONE do not drive evolution. You only omitted the key word in the sentence...Now we are making progess. Since, as you say, mutations do not drive evolution, why are so many in this discussion saying they do?
It doe snot
Yes. If that idea surprises you, you are sorely in need of an education in biology.and DNA proves it. Plants have DNA. Do we have a commone ancestry with them?
I gave you a link with observed speciation events. What more do you want?
Is these the best examples you can provide? As Casey
Mutations bring about change in a living thing. Evolution is CHANGE. Now unless you understand that then we have nothing more to discuss as your knowledge of the English language is inadequate and there is no way anyone can explain to you how evolution works.
This is so clueless I don't even know how to deal with it.
All primates' DNA is different from all other primates. Otherwise there wouldn't be different primates.
Because you can change something that isn't already in existence?
The DNA for all species is different.
What about natural selection don't you accept?
First of all you have no real evicence that natural selelction is a fact. The kids don't get to select what traits they will get. Genetics does that for them. Even it was true, it is not a mechanism for evolution. The rabbit with the strogner legs might not become extinct, but it will only produce other rabbits and because of the gene pool of the parent some of hte kidsd may not get the stronger legs
1. Why 80%? What should it be 'at least' 80%? On what basis do you select that, specific percentage?
Tell many stages are needed for an A to evolve into a B. The point is that if evolution sqas true, the great majority of fossils would be transitiona and afte 100+years, y ou have zero
2. How do you define a transitional fossil? What would you accept as a transitional fossil? What features would it need to have?
I will accept any definition you choose, except things like a change in eye color. skin color etc are examples of transitions.
He said mutations ALONE do not drive evolution. You only omitted the key word in the sentence...
]Sorry, but you keep making this typo and it just cracks me up.

Some of them were much better than mine. I guessd I am just behind the curve.
Yes. If that idea surprises you, you are sorely in need of an education in biology.
