Yes...
But the problem is in education... you are a teacher...
Polygyny - one man, many wives
Polyandry - one woman, many husbands
Mammalian evolution - entirely heterosexual
I am counting on you as a teacher to be more exact in your instruction to the class room.
I can’t be any more exact than this:
1 man + 1 woman= civilization
Any other equation equals barbarism.
