I found that many friends of mine are quite easy in sexual relationship. Ex, I knew a lot of girls went to the night club & met a stranger & brought home to sleep with him even she had never known his name. The next morning, the guy left her & she starts to do the same way to get another guy maybe in 3 days or so.
So that triggered my thought. I wonder "Are early human beings (about 100 - 200 K years ago) far more promiscuous than we are now?"
My hypothesis is "Yes", that is "Early human beings are far more promiscuous than we are now". So how i came up this? Cos Human came from Chimpanzee right?, so if we want to know early human, then we could study Chimpanzee. The early human & Chimpanzee could have some similarities.
There is a research saying that "Chimpanzees are far more promiscuous than humans" http://www.nature.com/news/specials/chimpgenome/interactive/chimp_interactive_graphic_pf.html
So, that proved my hypothesis.
Also, when human evolved, they started to realized that promiscuousness wss not healthy & not good for society so they started to develop some regional/society (ex, monogamous relationship) codes to prevent that.
Do you approve my hypothesis?
