Some things never change I guess..
Yeah, like your insistence that ERVs are nearly extinct in humans because you misunderstood what "human lineage" meant... for 7 years.
I didn't ask about the jaw...
Look, I'm not going to spoon feed this to you so:
- It effects the jaw
muscle, not the jaw itself.
- If you have large jaw muscles, they have to attach somewhere. Guess where that is.
- If the muscles are smaller and less developed, the areas where they once were attached are unencumbered. Guess what they are free to do then.
Which is strange since the vast majority of the hominid fossils were found in close proximity to the savannas where the Troglodytes live now.

What? Common chimps don't live on savannas or very near them. They live in jungles in central and west Africa. The hominid fossil sites are in east Africa.
There are also orangutans and Eurasian primates from...hey you know what, I gave up chasing this in circles a long time ago.
You mean other populations that also live in jungles and forests - environments not conducive to fossilization nor the recovery of fossils?
Ok, based on a comparison of the SRGAP2 in humans to Chimpanzees the wild speculation based on pure presupposition is a favorable effect from a random mutation, imagine that. Guess proof isn't really required when you got presupposition working for you.
I'll take the analysis of actual experts in the field over some self-appointed expert whose argument boils down to "I don't believe it".
Human-specific evolution of novel SRGAP2 genes by incomplete segmental duplication
It is intriguing that the general timing of the potentially functional copies, SRGAP2B and SRGAP2C, corresponds to the emergence of the genus Homo from Australopithecus (23 mya). This period of human evolution has been associated with the expansion of the neocortex, use of stone tools, as well as dramatic changes in behavior and culture (Jobling et al., 2004).
Looked at some actual scientific data on the subject of mutations in the SRGAP2, it's the strangest thing. The effects of mutations are things like autism, schizophrenia and psychopathy. The only beneficial ones are the ones described as happening millions of years ago based on the differences between Chimpanzees and Humans. That doesn't sound like an explanation, that sounds like begging the question of proof.
Nice well poisoning. Because mutations can cause problems in some instances therefore no mutation could ever have had a beneficial effect. And where did you find this "actual scientific data" suggesting that mutation in SRGAP2 cause autism, schizophrenia and psychopathy? Or, as usual, are you misunderstanding something you read elsewhere?
Anyway, thanks for the fallacious logic, what would science do without that kind of circular logic?
Let's see. You didn't understand the significance of MYH16 and you did a bunch of furious handwaving for SRGAP2C and
I'm the one engaging in fallacious logic.
