It's all muscles. Why are humans so different from large animals?

Muscle structure is different. In addition to muscle differences, body structure is also important. The clavicle of orangutans is V-shaped, while that of humans is straight, so the arm strength is quite different. The body structure of cats and dogs makes their arm wrestling never inferior to that of primates, but four legs always run faster than two. . . Speaking of physiological structure, it should be a flea, with four legs, and everyone knows how much it can jump.

Don't say that animals exercise regularly to strengthen their muscles and bones. Some domestic animals do not necessarily exercise more than people, but they have incomparable advantages in specific projects.

Humans have hidden their strength in evolution, and their muscle efficiency is not that great. Potential can be stimulated in an emergency or through training. Primates, on the other hand, have been doing their best almost all the time.

Because hidden forces tend to use tools, and consume less calories, and have less time to eat and forage, this is a suitable evolutionary path for humans who have already fallen from trees.

There is a so-called "reproductive selection" in the theory of evolution, just like why the tail feathers and crown of male peacocks become more and more gaudy and cumbersome with evolution. In fact, these two things are useless for survival. But the mother peacock likes this style! When a peacock man with beautiful tail feathers and a crown appears in front of the female peacock, it is simply the F22 of the peacock, and a group of female peacocks will surely rush at him while calling "Husband X Me". So the more beautiful the feathers, the easier it is for Peacock Man to inherit his own genes. So the male peacock's feathers are more beautiful and heavier, like an arms race.

In the aspect of gorillas, the gorilla population is the organizational structure of one man and many women. Only the most powerful and capable male orangutans can gain leadership and have three palaces and six hospitals in the orangutan world. Therefore, under the influence of reproductive selection, only the strongest male orangutans can have offspring, so the gorilla's constitution is getting tougher and tougher.

Australopithecus, the ancestor of human beings, is actually another organizational structure, similar to chimpanzees. They have no absolute leader, and a large number of male and female chimpanzees live together. NTR is something that happens every minute (). Under this organizational structure, individuals who are more communicative can gain leadership positions. Chimpanzees have many natural enemies, and large carnivores are their enemies. On the other hand, adult gorillas have no rivals. In order to protect themselves, there are always people who are responsible for observing the enemy's situation, which improves the intelligence requirements of chimpanzees. Therefore, each generation of chimpanzees are individuals with high intelligence and good communication skills, and they can leave their offspring, which is naturally much smarter than muscular gorillas. Circus trains gorillas. Chimpanzees can't train gorillas. The gap in intelligence can be imagined.
