The Science Of Monogamy

Monogamy is a longstanding social norm around the world, but it wasn't always that way.

But scientists do have a lot of theories on the nature of human relationships, and you can catch up with their latest observations and studies by watching this video from AsapSCIENCE.

"Nobody does that anymore," Crosby told Civilized.
