Which indicates that there ARE beneficial mutations.
But not in genes related to human brain funtion.
First fossil chimpanzee. [Nature. 2005] - PubMed result
Incorrect.
Completely out of my field of knowledge. BUT, if I had to guess, looking at the abstract of the article I just linked, it would likely be location.
Ok, that article appeared in the same issue of Nature that the Chimpanzee Genome paper was published in back in 2005. It consists of 3 maybe 4 teeth and that is it for well over 5 millions of years of chimpanzee evolution while our supposed ancestors are represented by hundreds of specimans and literally thousands of fragments.
As to the other matter if you had followed the link you would have found where Taung was discovered. It was discovered by Raymond Dart and for 50 years it was considered little more then a chimpanzee. With the demise of Piltdown Dart's fossils found credibility, probably because there were no suitable canidates for the mythical human/ape transitional. It had a chimpanzee size skull, point blank, flat out.
But if there isnt time nor means for it to have evolved then it MUST be wrong, because for it to have evolved is an impossibility, and therefore anything showing it to have evolved is incorrect. No?
There was neither the time nor the means and there is abundant scientific research available indicating exactly that, if you ever bother to research it.
Yes, I know it wasnt worth much. BUT in between now and then, I did some research and remembered it.
Brain endocasts. Lunate Sulkus (no idea if I spelled that right).
And:
NOVA | Becoming Human Part 1
chapter 4, about 19 minutes left in the program till about 16 minutes left. Theres some more later in the program about Homo Habilius, but I dont remember where.
I would hope THAT is worth a lot more than the rambling I did last post.
Catch watch that special here as much as I would like to. Lucy and the speciman in question are both apes with chimpanzee size skulls. I would like to see there series though, maybe in a couple of months when I get some leave.
I would completely disagree. Being unable to isolate single gene changes that are undisputedly beneficial today is not equal to starting with a different and more primitive brain in a completely different environment working towards what we have today.
No it's not different, brain related genes result in disease and disorders not improved fittness. Environment has nothing to do with it if there is no molecular mechanism that can be triggered by external conditions. Other things can and do, apendages, metabolism, color, texture and a host of other traits. Vital organs on the other hand simply don't respond favorably to mutations.
Theme #1 of your post:
Because we havent found undisputedly beneficial mutations in the human brain, they are impossible and thus so is the non-human ape to man transition.
That's the gist of it and no matter how many times I bring it up not one attempt in 6 years to refute me.
I still have extreme reservations about this that fall into several categories.
The environment we have today, with civilization and all, is far different than uncivilized Africa tens/hundreds/thousands of thousands of years ago.
Humans, unlike apes, have inhabited every ecological niche on the planet and we do not change substantially from one another. We do not speciate for one thing even though both gorrillas and chimpanzee do. We are talking about chimpanzee like creatures living in Africa 2 1/2 million years ago and the climate and environment would not have been dramatically different from today.
Starting with a current human brain and trying to get it to go forward and stating that if we cant get it to go forward means nothing could ever lead to it just seems... more than a little nonsensical to me. Just because we dont know how to manipulate genes to go forwards (or how they might be manipulated by nature to do so), it does not follow that it is impossible for them to have arrived at this point from something else. The notion is FURTHER complicated by the fact that we dont have anything that was a direct predecessor to us, only other brains that have gone thru divergent processes as well. And going Back would be a problem because we dont have a back to compare it to.
The problem is that we don't have chimpanzee ancestor fossils to compare our abundant hominid fossils to. The closest we can get as far as I can tell is Euroasian apes and that is well over ten million years. The simple fact that not one single molecular mechanism for the overhaul of the requiste genes exists and yet the common ancestry of humans and chimps must never be questioned. When you don't have a directly observed or demonstrated reason then you simply don't have a scientific explanation. What we are dealing with here is a naturalistic presupposition that dismisses God's miraculas interpolation before the evidence is ever considered.
I still maintain just how hard it is to figure out the difference between genetics and environment (nature/nurture) it would be to find just what is normal for the human brain, and what would be caused by mutations. Photographic memory, intelligence, personality, etc COULD all be mutation controlled, no? But is this known for certain? How far above human norm does a persons intellect have to be before we would start looking for mutations controlling it? What about less well known possibilities, like a non-degrading axon sheath that would resist Alzheimer's disease? And how to know this unless you are blatantly coding the DNA of at least a statistically significant portion of the entire human population PLUS extraordinary individuals (cue hundreds to millions of Christians decrying the effort as an attempt at instituting the One World Order by getting peoples genome on file for future control and identification).
Actually, Francis Collins (head of the Human Genome Project) lobbied for legislation to prohibit genetic profiling by insurance companies. At any rate, all you have to do is to compare two DNA sequences, nothing Orwellian or New World Orderlyish about it. If there existed a single positive proof that a molecular mechanism existed or random mutations could it would be splashed across every scientific publication in the world. Meanwhile, back in reality, mutations effecting the brain continue to cause disease and disorder every time they have an effect. This point is, in fact, irrefutable. No one ever even trys.
Your answer as to the reason WHY they would do such a study was only Because they need an explanation for the three-fold expansion of the human brain from that of apes before they can call it a fact. However, not every evolutionary change DOES have a full-fledged gene-by-gene description of what happened to make it so. If you accept ANY other change that we dont have the genetic evidence you demand of human brain changes, then you are applying a double standard. If you dont, then what would be next after the human brain? The loss of the penis bone? (being entirely serious here) Cats divergence from dogs? (if we cant make body shape gene changes in cats that are obviously beneficial, the fact that cats and dogs had a common ancestor cant possibly be true). And of course, since we dont have an exact genome of THAT things body, how difficult will that be? You see where Im going with this.
I think I know what your getting at and I would love it if it were possible to compare every genome on demand. We only have complete human and chimpanzee genomes to work with and the requiste genes are all I am really concerned with.
Another theme I saw was more of a contradiction. You specifically stated both:
but then went on to state such things as
which leaves me quite in the dark at your apparent self-contradiction on whether or not any beneficial mutations ever actually happen.
Benefical mutations happen, just not in the gene related to human brain development.
I would also like to point out how you seem to roundly ignore/discredit/look down upon fossils. Even if genetics cannot reconstruct every step of the way back to some unknown intermediate and back again, fossils that SHOW various steps along the way are still evidence. I just got a feeling of extreme venom towards them, and I want to point out that OF COURSE if you throw out one whole huge line of evidence what is left is not going to be anywhere near as convincing.
And to finish off,
I have never ignored or discredited fossils, that's just plain silly. I rely heavily on the fossil evidence for my arguments and link often to peer reviewed articles and credible sources often. I consider fossil evidence to be giving us a clear indication that the chimanzee ancestors are all in natural history musuems marked Homo XXX. I do not come on here to study evolution as much as I study evolutionists.
I really have no idea what you are trying to get at. None whatsoever. I mean, the closest one word I could fit there might be knowledge, but that would lose almost all of what I meant. The Gospel of Jesus Christ is about Gods love, sacrifice, the salvation of man and our immortal souls. Not about natural history, evolution, ape-man genetic relations and origin, etc.

That's right, knowledge is the literal meaning of science. Now we are talking about natural history and there is a correlation between both natural history and redemptive history. Both rely on evidence and since they are in direct contradition only one can be reliable. How would you say that the evidence for the New Testament stacks up against the evidence for the stone age ape men like Homo habilis?
I'm not teasing, that is actually a serious and important question. How you answer it is not as important as the fact that you consider the question.
