Ok, so the Psych's have proven it:
Psychology Today: Ten Politically Incorrect Truths About Human Nature
Humans are naturally polygamous
The history of western civilization aside, humans are naturally polygamous. Polyandry (a marriage of one woman to many men) is very rare, but polygyny (the marriage of one man to many women) is widely practiced in human societies, even though Judeo-Christian traditions hold that monogamy is the only natural form of marriage. We know that humans have been polygynous throughout most of history because men are taller than women.
Those darn Christians & Jews anyway!
