Dog homosexuality refers to courtship or sexual behavior between adult same-sex dogs. Scientific research shows that homosexuality exists not only in human society, but also in at least 130 species of vertebrates.
Experts believe that homosexual behavior is common in the animal kingdom and can be said to be normal.
Li Chunwang, who specializes in animal behavior research at the Institute of Zoology, Chinese Academy of Sciences, said that homosexual behavior has been found in the animal kingdom from birds to mammals. They generally call it "homosexual contact" or "homosexual crawling".
Li Chunwang believes that this "same-sex climbing" behavior of animals is influenced by innate factors. Animals generally have seasonal estrus. At this time, the animals have matured and the process of energy accumulation has been completed. Stimulated by sex hormones in the body, they will have impulses and show courtship and mating behavior.
However, in some populations with more females and fewer males, or in populations with very strict hierarchical sequence, excellent male animals often win the favor of female animals. For example, during the mating season, the stags in the herd will compare whose hooves are bigger and whose bodies are stronger; Pheasants will see whose feathers are more beautiful; Tits are more pleasant than others. ...
Female animals choose those excellent male individuals for mating, and the remaining "bachelors" are not qualified to participate in breeding groups if they can't find a spouse. They can only have the same-sex crawling behavior to release the accumulated energy in their bodies.
"Same-sex comparison" is also a social behavior, which is influenced by the acquired environment. As long as the right environment is created, homosexual behavior can often be induced.
Li Chunwang said that most dogs' homosexual choices are temporary. When individuals of the opposite sex appear around them, they will immediately abandon their homosexual identity and pursue the opposite sex.
However, some animals will not change their original intention even if the opposite sex appears after forming same-sex couples.
Li Chunwang explained that homosexual behavior of animals is sometimes just a learning behavior. For example, when young primates play games, they sometimes have some crawling behaviors. At this time, they are only sub-adults, immature, without mature sexual organs and adequate sex hormone stimulation. Crawling between them is not sexual behavior, but the behavior that small animals imitate between adult animals. But this kind of learning is very useful for the later reproductive behavior of animals.
Other same-sex behaviors are aimed at relieving the pressure of the community and expressing mutual friendship. Antagonistic conflicts often occur between individuals of social animals, especially between animals of the same sex. For example, bonobos are excitable animals, and they often fight over trifles. However, their fight seems to have subsided faster than it happened, and one way is through sex.
Two people of the same sex rub each other's genitals, while the opposite sex has real mating behavior. They use this behavior to show goodwill, calm down the fight, and thus reduce the losses of their families and themselves. It can be seen that homosexual sex has the function of maintaining the stability of animal population.
Homosexual behavior and its environmental induction
The function of homosexual behavior
Life evolution is a long process of survival of the fittest, and all life forms that can be preserved to this day have their reasons for existence. It is generally believed that from the ultimate function of sexual behavior-reproduction, same-sex mating can not produce offspring, which is a wasteful behavior mode. However, this phenomenon is widespread in the animal kingdom so far, so it has certain biological and animal sociology significance. The following are some common biological functions of homosexual behavior:
The evolution of the animal world is very long and complicated. In this process, various physiological and subconscious behaviors of animals are still maintained. With the further development of conscious activities, this phenomenon will inevitably be introduced by many conscious factors, thus making homosexual behavior more chaotic.
The world is full of wonders, and the homosexual behavior of animals needs further study and discussion.
