The pace of human evolution has been increasing at a stunning rate since our
ancestors began spreading through Europe, Asia and Africa 40,000 years ago,
quickening to 100 times historical levels after agriculture became widespread,
according to a study published today.
Altogether, the recent genetic changes account for 7% of the human genome
Among the fastest-evolving genes were those related to brain development, but
the researchers aren’t sure what made them so desirable, Hawks
said.

There are other mysteries too.

“Nobody 10,000 years ago had
blue eyes,” Hawks said. “Why is it that blue-eyed people had a 5% advantage in
reproducing compared to non-blue-eyed people? I have no idea.”
