I was looking at futanari porn and thinking about evolution the other day.
With the way evolution works, beneficial characteristics usually end up surviving in a species because it helps them adapt to their environment. If that is so, wouldn’t efficiency dictate that more animals evolve into hermaphrodites? Instead of having to find a mate, you’d reproduce with at a near 100% rate.
But then evidence shows this not to be so, and that got me wondering why that is.
While more efficient, its more complicated internally. Having to have 2 sets of sexual organs means twice as many things can go wrong.
It’s more beneficial to the offspring with 2 parents. Even though not all animals stay together once the babies are born, or even conceived, in the cases that they do, it helps survival rates.
Birth is dangerous for the mother. In a vulnerable time such as childbirth, it helps to have someone else guard the cave and hunt for food.
So is there some kind of scientific consensus that says why more animals aren’t hermaphrodites?
