Sexual Dimorphism and Human Evolution

Introduction In contemporary society, the gender theme must be handled carefully. Due to political correctness, gender is full of emotion and full of ideas, and gender may be a cumbersome problem especially in discussions related to behavior and social behavior. Throughout history, many people are trying to understand the difference between men and women. Until today, this topic was generally discussed by religious leaders and philosophers.

The duality of human sex is controversial. Humans are thought to have a different appearance between men and women, but Homo sapiens has a lower level of gender gender compared to many other species. The similarity between male and female human sizes is a good example of a nature that is not usually clearly defined. In order to accurately explain the difference in size between male and female, it is necessary to indicate how many people are in each figure. There is considerable overlap

Sexual type 2 is a physical difference between male and female species. Inverse dimorphisms when females are larger than males are observed with multiple owl species. The degree of dimineness in size is different among multiple groups and species, and it is measured by various characteristics such as wing width and weight. Generally, female owls tend to be slightly larger than men. The exact interpretation of this development of the owl is unknown. However, there are several theories that explain the development of oddroidism.

Another very interesting feature of primitive human evolution is the degree of sexual duality in different species (ie physical differences between sexes). Gender dimorphism is related to the social and spouse competition characteristics of many kinds of animals. To understand the evolution of this feature in humans with a relatively low sexuality, we need to consider other apes that tend to have moderate to high gender dimorphism (some With the exception of). There is not enough evidence to prove that Sahelanthropus, Orrorin, and Ardipithecus know a lot about gender differences in these species, but I know that A. afarensis has a relatively high gender difference. A. africanus, Paranthropus and most Homo genealogies, the differences seem to be small. A. The evolutionary interpretation of the afarensis' s decymorphism is not entirely clear. Some or all of these functions may function.
