Why have humans evolved in such a short period of time?

The history of human evolution is not short at all, starting from apes is more than 3 million years, starting from primates is about 60 million years, and starting from the most primitive life on the earth, it has gone through 3.8 billion years. It may be that human beings are able to evolve in a short period of time because they are intelligent. However, intelligence is a function of the human body itself, which evolves quantitatively from the natural energetic biosphere, and evolves in response to the evolution of other organisms, and nothing can evolve in a short period of time.

All living things on the earth are evolving, and the so-called evolution is not a change in the individual image of living things, but a change in the genes of key life substances. Moreover, the change of individual genes has little impact on biological evolution, because biological individuals may die at any time, and may not be able to pass on genes due to other factors, and the frequency of each gene in the population gene pool is little affected by individual genes.

Human evolution is the result of various accidental factors, because of the competition for survival, there is not enough food to eat, and they are driven out of the jungle, so they need to open up new territories and try new foods, because they enter a new environment, biological genetic mutations go in different directions. On the ground, humans mastered upright walking, genes were selected by the environment from generation to generation, and finally the skeleton and muscle structure of individual human beings were fully adapted to upright walking. The greatest ability of human beings is probably the application of fire, because all living things on the earth are carbon-based organisms, and carbon organic matter cannot resist fire, so most creatures are afraid of fire, but human beings have mastered the application of fire.

After the application of fire, the human diet changed, the digestion and processing of food was faster, and the brain could get adequate nutrients. As a result, genes related to intelligence are screened layer by layer, and the human brain capacity continues to increase. It was also because of the application of fire that humans made more convenient metal tools, freeing them from stone tools.

Eventually, apes evolved into modern humans. And all the other living things have changed a lot, but in general we pay more attention to human evolution.

In fact, human beings did not evolve in a short period of time, and it took a long time to evolve into human beings, but now people are getting smarter and smarter, so they think so.

Because people are good at learning, they will always innovate after learning something, so they will evolve very quickly.

I think the evolution of human beings has been continuous, and it has taken hundreds of years from ape man to the present.
