Did Humans Get Their Big Brains From Neanderthals? 579
MCTFB writes, "According to CNN, human beings may have acquired a gene for developing bigger brains from Neanderthal man. Apparently, 70% of the world's population has a variant of a gene regulating brain size, with this variant being most common in people of European descent (where Neanderthal man lived alongside ancient humans), and least common in people of African descent (where Neanderthal man was non-existent). While modern day eugenicists might all too eagerly read into these findings to draw their own politically biased conclusions, people such as myself, who happen to be of northern European ancestry, may find it fascinating that somewhere in our lineage ancient humans and Neanderthals decided to make love and not war on the ancient plains of Eurasia."

But that doesn't seem very likely, does it? It amazes me that this kind of thinking gets anywhere at all.

They're basically studying a haplogroup of the microcephalin gene [wikipedia.org], and show that this gene probably entered the human lineage before 37KYA. The other haplogroups have coalescent times of circa 100KYA (which is around when Homo sapiens arose).
They then use some statistical magic to show that the early coalescence time for the D haplogroup was probably a result of introgression into the population - i.e. it came from another population. Note that they don't stress that it was Neanderthals, it could have been any archaic Homo lineage.

There's something called viral gene transfer, and if I understand correctly it works partially through retroviruses. I expect that if there is human/neanderthal gene mixing, it is more likely to have been through viruses that the mixing occurred.
Another possibly false assumpt ion that was not made outright, but implied, is that there is merit to a larger brain. I'm not so sure that's correct.

The article mentions that more neanderthals lived in europe than africa, and that distribution of this gene that may or may not have come from neanderthals corresponds to that. However, the article also mentions that *70% of the human population* has this gene. If the gene's presence in africa is lower, they don't say how much lower. The data mentioned in the article gives no indication whether the gene is present in a majority or a minority of africans.
Given all of these qualifications present in the article, the submitter was obviously trying to spice up his submission to get it posted by playing up the race element and drawing a strong connection between this gene and race *that the original article doesn't actually show*.
Personally, I would be curious to see more of the data that these people collected; maybe even see the actual distribution of this gene by geographic location.
