Asexual reproduction is very simple, why did it evolve to be male and female?

Asexual reproduction is only to produce individuals, and the genes of offspring individuals and parent individuals are exactly the same, and if the environment changes, it is easy to become extinct, and the combination of male and female can promote the production of variations that adapt to the environment.

The offspring of asexual reproduction are the same as the genotype of the parents, and the lack of genetic diversity can easily cause the extinction of the entire species when the environment changes, which is not conducive to the development of the species. Sexual reproduction, on the other hand, can ensure the diversity of traits and facilitate the reproduction of offspring.

Asexual reproduction is simple, but it produces deleterious mutations. After the organism has sexual reproduction, there is a chance to produce an individual to get rid of all harmful mutations, so that the organism can evolve faster and more steadily, and have a stronger competitiveness.

Because it's blocked.

This experiment was mainly carried out by British scientists, but was often blocked by the British**. There are also scientists in China who have successfully achieved double female breeding of rats.

Double-female breeding has been shown to have a longer lifespan than hermaphroditic breeding in mice.

This is a bit similar to a man showing off his car, house, money, and muscles in front of the woman he loves. The male is brightly colored, which is to tell the opposite sex, you see that I am brightly colored, the color is prominent, and under normal circumstances, I am easier to eat by ** eaters, but I survived, and I am still thinking about your courtship, which shows how capable I am and how strong my genes are, hurry up and mate with me and let us give birth to cute genetically strong babies together.

The female is solely responsible for the rearing of offspring.

When the female is pregnant, her mobility is reduced, and the male is responsible for going out to find food and protect the female, and in the long run, a division of labor has been formed, with the male responsible for foraging and protecting the female and her offspring, and the female responsible for giving birth and caring for the offspring. The combat effectiveness, physical strength, and body size of males are developing in the direction of their own division of labor.

At the beginning, reproduction and reproduction need to be well divided.

This is the result of natural evolution.

Because females are protile, have you ever seen a male who can give birth?

Because of the different division of labor, male and female are distinguished according to the division of labor.

This is the law of nature, prescribed from the beginning.

Most are males who are only responsible for mating.

It is also the result of the long-term evolution of living things.

The male is responsible for protecting the family and dividing the work with the female.
