Human Brain Size and the DUF1220 Gene

Researchers have found what they believe is the key to understanding why the
human brain is larger and more complex than that of other animals.

The human brain, with its unequaled cognitive capacity, evolved rapidly
and dramatically. [QUOTE]

Interesting bit…

“The protein domain at issue is DUF1220. Humans have more than 270 copies
of DUF1220 encoded in the genome, far more than other species. The closer
a species is to humans, the more copies of DUF1220 show up. Chimpanzees
have the next highest number, 125. Gorillas have 99, marmosets 30 and mice
just one. “The one over-riding theme that we saw repeatedly was that the
more copies of DUF1220 in the genome, the bigger the brain. And this
held true whether we looked at different species or within
the human population.” [QUOTE]
