Can reproduction only be done by the opposite sex? Which creatures are on their own?

Reproduction must rely on the opposite sex? The strength of these natural creatures is interpreted entirely on their own.

First of all, it is determined by the natural attributes of human beings. Human reproduction offspring is mainly the genetic inheritance of parents, and the child's appearance, physique, personality, IQ and other factors are related to genes and are part of bloodline. Secondly, people who are related by blood have the care of family affection and can feel the warmth of the family, and the importance of family ethics in the human moral system is self-evident.

If there is no blood relationship, you will feel that you are an outsider everywhere in this family, which is very painful.

Of course, blood ties are important, and so is companionship. Husbands and wives are not related by blood, but they can accompany each other for a lifetime, longer than blood relatives. There is another important factor in this, that is, the two parties have their own children together, and with the blood bond of the child, they can live their lives together without major changes.

Also, for adopted children, "the biological mother does not have an adoptive mother", and the blood relationship is not so important. The situation of a child born with a "hat" is more complicated, although the child is innocent, but the injured father does have a blood knot.

Generally speaking, with the development of the progressive society of the times, the decrease in the number of children, and the simplification of kinship based on blood, it is very likely that the blood relationship in interpersonal relations is becoming more and more diluted, and the interest value relationship has become the mainstream and essence, dominating the vast majority of interpersonal relationships. The status of blood ties will gradually decrease, and the importance will gradually diminish. Although that kind of world is terrifying, the law of evolution of things is like this, irresistible.

The blood relationship in the new era is basically the relationship between giving and returning, which is a strict requirement for the moral cultivation of parents and children. Parents should be civilized and qualified parents, and children should be kind and grateful children.

If the pay and return are equal, the blood relationship will be sustainable and harmonious; If there is no equality, it will be a test for the two sides, especially the one with a gap.

Other creatures? Like other organisms, they have to reproduce, and one of the major goals of all living creatures is to reproduce, and those that do not reproduce will become extinct early.

All creatures have to reproduce like that.

Because reproduction is the basis for the continuation and development of living things, otherwise the species will become extinct, so people must reproduce.

Reproduction is indispensable for the continuation of the race, and the survival of the race is the most important for human beings as the top of the biological chain.

The essence of human beings is also animals, and since they are animals, they have the instinct to reproduce, and reproduction is not only their own business, but also a major event related to human beings.

For the sake of human beings, human beings can only continue to continue if they reproduce their offspring.
