I was told all humans start as female and then the ovaries descend and become testis. Why are females limited in this capacity?
In: Biology
The answer has to do with sexual competition in all sexual species. Females spend more energy on fewer and larger gametes while males compete making many small gametes which only have a small chance if making it to fertilization. A female doesnt need a shit ton of eggs. She only needs one for every menstrual cycle. It’s not that females are limited, really males are wasteful. Males compete with each other by producing the most sperm. If a man has sex with two women in the same night they can both have his children but if a woman has sex with two men she can only bear one child at once so the one who gave her the most and strongest sperm has a better chance. If our primate ancestors hadn’t been so polyamorous maybe males wouldn’t have to spend their energy making thousands of sperm but that’s how things are.
