Sounds rather flimsy about the dialing back of violence given more humans have been killed by war in the past century than any century previous. As well we are still a violent species that slaughter each other wholesale when given a chance.
What I can buy into is a more collectivist society forming 50,000 years. I have no idea if a skull shape has anything to do with it. The skull shape could also be a result of selective breeding due to more available males to choose from with the female population. In other words the huge brow was not an attractive feature. When given the chance the female population didnt procreate with that population and that trait died out as a result.
