Why are there men and women? Why can men have so many women?

Some scientists in the United Kingdom believe that the reason why humans have only two sexes, male and female, is because a long, long time ago, a bacterium infected our ancestors.

The belief that there is no limit to the diversity of life on Earth has led scientists around the globe to a question that has puzzled scientists for years? Why do most species on Earth have only two sexes, male and female.

Of course, there are exceptions to this situation, with 36,000 sexes for common mushrooms and 13 sexes for another fungus that lives in a sludge bog, but they are only a tiny exception to the usual laws of both sexes on Earth. The more genders, the greater the ability of the race to reproduce. So why do human beings, as the spirit of all things, have only two sexes in the long evolutionary process of survival of the fittest?

Professor Lawrence believes this is determined by the specific genes we inherit from our ancestors – mitochondrial genes.

Since mitochondrial DNA can replicate quickly, if a person has 100 sexes and is not mutually exclusive, any little variation in the mitochondria will spread quickly, which can lead to catastrophic consequences.

Therefore, although the two sexes are more limited in the choice of partners, they also avoid the catastrophe that genetic variation may bring.

If there are no men and women, where did you come from?

Someone once said: Men are amorous and affectionate. And women are dedicated and ruthless.

A man can have one or more "she" in his heart when he is already with someone he likes. Because he is amorous. A man can still think about whether his girlfriend is okay or not years later. Because he is affectionate.

When a woman is with someone she likes, all she thinks about is him and what she does is for him. At this time, even if a better man appears than now, she will not give up on him. Because of her dedication.

And when she decided to give up on him, that was to say that there was no room for anything. Because she's heartless.

A man is amorous by nature, and he will be the most affectionate to a certain person, but the probability of this person becoming his wife is almost zero.

A woman is naturally passionate, she will be the most ruthless to a certain person, but the possibility of this person becoming her enemy is almost zero.

Men and women are really different. When a man knows that his former girlfriend is having a bad time now, he will comfort her, and when a woman knows that his former boyfriend is not doing well now, most of them will definitely not comfort him.

Women don't understand how a man can have so many hearts to remember so many feelings. And men don't understand how women can be so determined to forget about a relationship.

For example, men and men love to put on their shoulders to show friendship, and women and women love to hold hands to show friendship. Comparatively speaking, men love to laugh when they are happy and unhappy. As for women, she will laugh when she is happy, and cry sadly when she is sad.

Manly, bleeding without tears. What about women? If she was smiling when she was sad, others would have thought there was something wrong with her.

When a woman is determined to break up with you, you should not think that you can leave her person and heart behind, because women will not easily say the word breakup. However, when a man says he wants to break up with you, he has to work hard, maybe you will have a chance. It's very simple, it's affectionate and long-term, dedicated and unlovely.

When a woman is fully committed to a relationship, her heart is unbreakable. But when a man is fully committed to a relationship, there can still be a gap for another her to take advantage of.

Because since ancient times. Men put their careers first. In society, there are many more men than women who have careers, so men can support several women.

And there are not many women who can support several men, and even if she can afford them, how many men are willing to let women support him? So it's all men who can have a lot of women.

Maybe men have developed a very bad ideology from ancient times to the present, in fact, as a man, you should also be loyal to your lover, so there will be a very balanced relationship between the two sides, and I think it will last for a long time. People, you can't talk too much, otherwise you may end up with nothing! I don't think every man wants to get such a result, so please cherish the people you should cherish!

Bless you!

Men can do women. Because which man can be deceived into returning words with many women because he is very handsome. The woman is because she is very beautiful, so many people can chase her.
