Why did man evolve and will man evolve?

Natural selection, survival of the fittest"Due to the changes of time, the changes of nature, in order to adapt to survival, organisms will gradually develop in a favorable direction, progress, which is the so-called evolution, it can be said that nature has prompted the evolution of human beings, and it guides organisms, of course, human beings in a relatively strong way. For example, the ancestor of humans was the forest ape, but due to natural and other geographical changes, some of them moved to the land to survive, while the other part still lived in the trees, which are the two parts of the forest ape branch: humans and apes.

It is clear that humans are the most advanced creatures, which proves that nature has had a great influence on human evolution. And then from Australopithecus to Homo erectus to Peking Man (and Homo sapiens, modern humans are Homo sapiens), this is also a piece of evidence.

I haven't read Darwin's "The Origin of Species" specifically, but I still know the general truth, everything is in motion, and so are living things. Therefore, when the world outside of living things changes, the living things themselves evolve in order to survive.

As the name suggests,"Evolution"It's called getting stronger and weaker"Degradation".Whether it's in the moment"Doctrine of African origins"or other theories, all of which prove the long way human evolution has come.

In a word,"Natural selection, survival of the fittest"

The need to survive, the result of competition.

According to scientific theory, life on earth is in the process of evolution all the time, and man, as a higher animal, is no exception.

You can't see it, but you can see it. For example, the cecum of a person is constantly degrading because it is not used. So, maybe in many years there will be no cecum.

For example, the vitality of the Y chromosome is gradually declining, so some people say that in the future--- of course you will not see it--- there will be no men, depressing!

Constant evolution is the only way to satisfy the choices of nature, that is, the universe. In the face of the universe, man can only evolve.

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

As a result of natural selection, in order to be more adaptable to the environment, in order to keep the genes of the race alive, organisms will continue to evolve.

Any organism is changing faster or slower, these changes are harmful to their survival and reproduction in nature, and some changes are beneficial, the species that have beneficial changes will occupy a more advantageous position in the competition for survival and thus increase their number or share, while those that have harmful changes will be in a disadvantageous position and gradually decrease and be eliminated, so the biosphere is always replaced by species that are constantly undergoing beneficial changes, this phenomenon is "evolution".

The same is true of human beings, who are constantly evolving, and those who evolve slowly or not evolve are gradually eliminated after a period of time, and today they can only be seen in ancient strata.

Because in ancient times, human beings had to constantly exercise to avoid starvation, so the option of "exercising, not exercising" did not exist in ancient times, and if you want to live, you can only be exhausted, and in this process, human beings have learned three things:

Try not to move, because exercise is all about survival, so try not to move when you can, to conserve physical strength, and in the same way, humans will store excess energy for emergencies, so most people don't actively exercise, and they get fat.

Human beings have a basal metabolism, which means that you spend energy while lying down, and this basal metabolic rate is related to your lifestyle, and when you don't exercise, the body gradually lowers the metabolic rate, breaks down muscles, and there are fewer red blood cells and so on, and this is the same as above, in order to reduce consumption.

In ancient times, the average life expectancy of human beings was very low, usually no more than 40 years old, so the parts of the human body are adapted to begin to degenerate and damage around this age, because there is no cost for any function, since you can't live that long, there is no need to waste excess energy, and the same is true for excessive exercise, the durability of human body parts only needs to adapt to the movement of most people, and it is not necessary to be very strong, so when you repeat a movement for a long time, it is easy to damage the parts.

This natural change, everything has to have a limit, the machine will rust if not used, and overuse shortens the life, all of which are the reason. Aging is an effect of human genes that may be resolved later.

Because the human brain is larger than other animals, accounting for about 5% of the body volume, brain cells are more developed, so it has evolved into what it is today, thank you!
