Why do humans have genders, and there are only 2 genders?

When Nuwa created people, they separated men and women, and only when there was a gender could they reproduce, and the two sexes complemented each other.

Nature has long created the two sexes of human beings, and the combination of many is particularly chaotic. So just create two genders, and it's enough, and you can control the natural world very well.

It is the result of biological evolution, because when it comes to human marriage, three or more people are not stable.

I don't know that there are only 2 kinds of human genders, and many animals in nature have 2 kinds of sexes, which may be caused by the laws of nature.

This is determined by the genes of human evolution. Genes determine that we human beings will be divided into two genders, male and female, to survive and reproduce, and only with gender can life continue.

I think the first reason is for the reproduction of offspring, and since ancient times, both animals and humans have needed to mate and reproduce the next generation. The second is to make a distinction, if there are three genders, one male and one female, what should the other be? One gender is not good, two are best, and more than three are unscientific.

Because this is determined according to the physiological function of human beings, human beings of both sexes can already be satisfied with the reproduction of future generations, and at the same time, it is also the result of natural selection.

First, it's about "why is this happening?"

The subject's reference to "there are a total of 56 genders in the world" should refer to the fact that in February 2014, an organization called Glaad in the United States cooperated with Facebook to expand gender selection to 56. The main purpose of the platform is to make the platform more inclusive of transgender and gender misplaced people. Among them, there are many specific information on the Internet about the specific classification of 56 genders, and descriptions can also be found in Chinese, so I will not repeat them.

I also looked up the UC Berkeley Gender Equality Resource Center.

Second, let's explain what transgender and gender misalignment are.

Transgender: Refers to an individual whose gender identity does not match their biological sex. For example, if the biological sex is male, psychologically they should be female.

Gender misalignment: refers to a person's inability to psychologically identify with his or her biological sex, resulting in a series of deviant behaviors, etc., such as a boy who thinks he should be a woman shows a series of behaviors that do not conform to his biological sex, which often leads to many physical and mental health problems.

3. On the "how to form" asked by the subject:

The diversified development of gender types originated from the change and development of people's thinking and the rise of the feminist movement under the wave of modern economic and technological development. These 56 gender classifications originated in the United States and are closely related to the feminist movement and gender equality in the United States.

When we usually refer to gender, we often refer to the biological sex that we are born with. These 56 gender classifications refer to people's psychological perception of what gender they should be in the sociocultural and historical background, which is a kind of reconstruction of the definition of "gender", giving it stronger psychological and social attributes. Due to the fluidity of cognition, some psychologists have also put forward the idea that gender is fluid.

In my humble opinion, I can understand it as a kind of "label" that describes my own gender identity, just as many people say "my personality is extroverted or introverted". But with so many gender types, we don't necessarily need to find a "label" to put on ourselves. The same goes for personality types, which are essentially meant to provide a way to better understand ourselves.

Each person is unique, and no personality test can accurately summarize your behavior, so it is good to look at it dialectically.

The criteria for judging are different, and the sex of a human can be determined according to the SRY gene, which is also a very critical factor.

This is because everyone's growth environment is different, and the status of women is getting higher and higher, so this situation will occur.

Gender is an option to be customized, and your gender can only be declared by yourself, everyone's personality is different, so there will be differences in gender, which will be divided according to 6 different levels.

This is related to the identification of the individual, and sometimes the identification of gender includes both biological and psychological aspects.

The universe is made up of yin and yang, and this is true for animals, people, and plants. Of course, there are very few special cases of yin and yang imbalance, but it still cannot be regarded as a third gender.

This is the mystery of the world, for the continuation of man.

Because that's how human genetics are determined. Human genes are only divided into xx and xy chromosomes, and the two sexes are conducive to better reproduction, so that the birth rate of human beings has been kept in a relatively balanced state.

Because the two genders are divided for the sake of succession. There is only one sex that cannot give birth to a new life. And there are two different chromosomes, which in turn results in two different sexes.
