"The foxes that turned into dogs"
http://www.bbc.com/earth/story/20160912 ... -the-world"In particular, one under-appreciated point about our species is that we have, essentially, domesticated ourselves.
This is borne out in our behaviour. While we have committed our fair share of atrocities,
on the whole we are far less aggressive and violent than our closest relatives, the chimpanzees.
This suggests that human evolution selected for cooperation, tolerance and gentleness
and not, necessarily, for intelligence.
"We always assume that intelligence is responsible for our success," says Hare.
"That humans became smarter, which… allowed us to invent wheels and agriculture and iPhones.
But what if that wasn't what happened?"
Hare suspects that, "like the foxes, and like dogs, we became friendlier first, and then got smarter by accident.
This would mean that our prosocial skills, the skills that allow for cooperation and friendliness,
were what made us successful."
