Gametes and Evolution in Humans
As we all know, males have sperm and females have eggs. Males have lots of sperm and females have only a couple eggs (156). Why is it that males create so much sperm, while women only have a couple eggs? What is the evolutionary significance? Could it be possible that males are suppose to have multiple partners if they produce so much sperm, and could this be a break for evolution stating that we are suppose to produce as many children as possible? If not, why is it that males create so much because isn't it a waste of energy?
