Human evolution speeding up?
The pace of change accelerated about 40,000 years ago and then picked up even more with the advent of agriculture about 10,000 years ago, the study says.
…The biggest changes have come since the end of the last ice age, about 10,000 years ago, which opened up new environments for the quickly expanding human population to grow from millions to billions.
More people mean more mutations, Harpending noted.
“You are also giving them the potential to be adaptive mutations,” said Brian Verrelli, who studies population genetics and evolution at Arizona State University in Tempe and was not involved in the research.
Hmmm…
Evolution has speed up since 10,00 years ago – for me this means since the last global cataclysm.
“More people means more mutations”. How about, more cosmic rays meant more mutations!
