Study Finds Humans Predominantly Monogamous Compared to Chimps

Study Finds Humans Predominantly Monogamous Compared to Chimps

A new study looked at how faithful humans are in relationships compared to other animals.

Researchers studied 103 human groups from different times and places, as well as 35 other mammal species.

They found that humans are about 66% monogamous, which means most people have one partner at a time.

This makes us more like beavers and less like chimps, which are not very monogamous.

The study also shows that being monogamous helps animals take care of their babies better.

Even though divorce rates are going up, the study suggests that being monogamous is natural for humans.

Different animals have different levels of monogamy, with some species like the California deermouse being very monogamous and others like the Soay sheep being less so.
