Talking about ape species： those orangutan species in the popular science ＂Rise of the Planet of the Apes 2＂

When it comes to Caesar, you have to mention the action to capture the first person, andy serkis

　

　　Great Apes are a general term for hominids, including humans and other orangutan races. Since biology is divided into the same subject, it is enough to show that orangutans and humans are actually very close, and the farthest DNA is 97.4% the same, and gorillas are 98.4%. There is no doubt that the closest relationship with human beings is the chimpanzee and bonobo, and the difference between chimpanzee DNA and human DNA is less than 1%. Caesar, the protagonist of Rise of the Planet of the Apes, is a chimpanzee. In the real world, chimpanzees are actually not big. When standing, they are 1-1.7 meters tall and weigh 45-80 kilograms. So in order to make Caesar and his companions more inclined to human beings, the film is actually magnified a lot.
　

In the second film, Caesar the chimpanzee also has his own wife and children.

　

　　The chimpanzee community is a polygamous patrilineal society, and the leader is usually an adult male. In The Rise of the Planet of the Apes 2, Caesar also has his own "queen" and son, and also lets mankind enter his territory in order to save his sick wife. But in fact, they are not so faithful as monogamy.

　

　　At the same time, the class of chimpanzee society is also very strict. Dewar, a famous American primatologist, once found that the low-level males will bow their heads slightly and extend their palms upward to the high-level individuals to show their respect. This is also a classic action made by many chimpanzees in the film to Caesar repeatedly, and each time Koba will "request" Caesar to be forgiven after not listening to instructions, but it is not as good as each time.
　

This "request" gesture is a way for low-level people to show their respect to high-level people.

　

　　In terms of food, chimpanzees are the only large primate that likes meat most and can use weapons except humans. Chimpanzees in the wild often organize hunting for wild boar, langurs or baboon cubs. In The Rise of the Planet of the Apes 2, the chimpanzee team silently marching on the dark rain forest ground actually existed on our planet. In the BBC’s annual nature documentary "The Pulse of the Earth" in 2007, these male chimpanzees living in the jungles of Uganda behaved like a real army, sneaking around, dividing up and attacking a group of chimpanzees nearby while the other side was unprepared, in order to occupy each other’s territory. Therefore, in Rise of the Planet of the Apes 2, those chimpanzee legions who wear armor, ride horses, attack humans, and even control humans as prisoners are not just artistic considerations. In order to survive, they absolutely have the strength to start a war among apes, not to mention Caesar whose genes have been improved by human beings.

　　But no matter how clever a chimpanzee is, can he really speak human words like in the film? The scientific answer is "NO!" — — Caesar’s "NO" that made the gods cry may be the cause of the genetic change, because the physiological structure of chimpanzees hinders their pronunciation like human beings. Their throats grow in a higher position, and their throat cavities are smaller. However, their long faces make their mouths longer and flatter, making it difficult for them to produce most vowels and consonants, which are often just instinctive roars or grunts. According to the continuous experiments of many scientists, the so-called "talking orangutans" have only mastered some words, not language, because the essence of language is an organized and regular logical flow, even though orangutans can sign language, they have never shown this.
