Our ancient ancestors might have been shaking up gender roles back in the day.
Colorado researchers found that, in two hominid species that lived on the South African savanna over a million years ago, the males preferred to stay close to home while the females were more likely to roam about.
The study team, led by Professor Sandi Copeland, looked at the social organization of distant human ancestors.
Copeland and her team were able to draw their conclusions by studying teeth from the ancient hominid groups.
Dr. Copeland tells us about this research and what her team learned on the “Science World” Radio program this weekend.
