What is sexual dimorphism?

Sexual dimorphism is a term describing the physical differences based on gender, which often exist in different species of animals. Experts have found that these variations exist for many different reasons, some of which are based on sexual reproduction, while others are based on practical gender roles in different social structures. Sexual dimorphism can be presented in many different ways, including differences in size, color changes or changes in basic form. Prominent examples include male lion mane or obvious size and differences between human sexes.

Sexual dimorphism can exist in many different ways in the whole kingdom of animals. Some of them could be considered somewhat obvious, while others are often very fine and may be difficult to notice it by simple visual identification for those who are not experts. For example, sexual dimorphism can be something relatively easy to score, such as a drastic difference in a fur color, or it couldBeing very difficult to see, as a difference in the meaning of the eyebrows. In some animals, gender look so similar that even experts cannot recognize the difference without the animal very carefully examining or performing tests.

One of the most commonly seen forms of sexual dimorphism is the difference between sexes. Men are usually larger than women, especially in different mammal species. However, there are exceptions, and in cases where women are larger, there is actually a special term for the situation: reverse sexual dimorphism. Some of the most important examples generally occur between specific birds and certain insects.

In many cases, there is sexual dimorphism primarily to serve as a help in identifying or to support sexual attraction. For example, in the alcoholic pea, a clear tail feathers helps a partner to secure a partner. In other animals would this kind of pThe anus could be generated from a change in its basic form or even another part of the body that excels visually.

There are also cases where there is sexual dimorphism primarily for practical reasons. For example, in some species the social structure determines different roles for gender. Sometimes a man or woman will have a specific job that requires some special physical attribute. The lion mane is generally a good example of this kind of difference. In the social environment, men usually fight with other men to protect pride, and the mane serves to make the man look enlarged, and also helps protect the throat during the fight.
