Finally, the term genetic monogamy is used when DNA analyses can confirm that a female-male pair reproduce exclusively with each other.

It’s all well and good to understand why the gray-handed night monkey became monogamous. From what they found, they concluded that hominids 4.4 million years ago mated with many females. Researchers point out that this probably isn’t the only reason we shifted toward a more monogamous society, since female choice also played a role, but it was a big contributor. Only 17 percent of human cultures are strictly monogamous. Our lineage never evolved to be strictly monogamous.
