The adoption of agriculture kicked off a very active period in human evolution, geneticists argue in a new

study. “Everything has changed about the way we live," says
@harvard.edu
geneticist Ali Akbari, "and that’s reflected in our genome and how it’s trying to catch up.”

The emergence of the domestic dog lineage occurred soon after the human expansion out of Africa 50,000 years ago. Now we have genetics to trace the evolution of man’s best friend.
