Early Human Dads Stayed at Home While Females Roamed

Males within two human ancestral species that existed roughly 2.7 to 1.7 million years ago were stay-at-home fellows, while females of these same species traveled, according to a new Nature paper.

The finding not only suggests that homebody males today may have a genetic predisposition for their lifestyle choice, but that certain female dispersal patterns among humans may mirror those of chimpanzees and bonobos. These two other primates also have stay-put males and traveling females.
