The new data suggests that the main biological effects of individual differences between human gender occurs primarily at the beginning of growth, especially before young people. Biostimulation tends to be regulated by a moderately simple process such as humor. Later, they develop more complex sex attributes for mature roles through group relationships (eg with ancestors and researchers). However, there are few studies on the basis of the evolution of the sex of a human child. Recent research by Lonsdorf and collaborator 2 is responsible for demonstrating these early gender differences based on evolution.
On 29th October 2002, David Watts observed that a young man named Grapelli attacked and killed a man from Ngogo chimp community in the Kibale National Park in western Uganda from his community. In the past two years, I spent a lot of time with Grapelli, and he knew him well during that time. He is a typical example of a young male chimpanzee with a clear oblique black sign on a rare light brown face. He is also one of the biggest and most aggressive chimps of Ngogo and he does not spend much time with the older, higher ranking men in the community. Instead, Grapelli leaves himself for several weeks, and when he comes back he will fight other men. When Professor Watts left the chimpanzee party on the evening of 28th and returned to them on the morning of the 29th, something suddenly happened to other men.
Essentially, all young men chimpanzees are pursuing the highest position in male rank of life known as male - male. To pursue a higher position, many male chimpanzees spend a lot of energy and are at risk of serious injury. Alpha men insisted on the rights of food and female partners, and he also gained a position to be protected from chimpanzees (Goodall, 1979: 616). However, the latter discussion deals only with attacks between groups (battle within groups within the same community); attacks on external groups are strange differences
The alliance is the main source of power for chimpanzees and humans. Among ordinary chimpanzees, the strongest men are not necessarily males - men are usually socially "smart" men and get the consent of most other members with the support of other "medium" can do. With this support, he can even beat more powerful opponents. The greater the alliance, the stronger will be the number of individuals less than the alpha male but in the ecological and social situation of the wild common chimpanzee the biggest alliance is men only It seems
