Males have greater reproductive success if they spend more time taking care of kids


Males have greater reproductive success if they spend more time taking care of kids—and not necessarily only their own, according to new research published by anthropologists at Northwestern University.

In a previous study, the researchers found that wild male mountain gorillas living in Rwanda do something that is quite unusual for a mammal—they help take care of all of the kids that live in their social group, regardless of whether they are the father. The goal of the new study was to figure out why.
