Why did humans fight for thousands of years but did not evolve a fighting physique?

It would be nice to build a plasma spark tower.

About our human beings living on our earth, this is an act of millions of years, to the earth as our human home, our human beings are currently using the earth is also constantly improving, I believe that in the near future, we human beings will change the earth to an unprecedented extent. So it is an undeniable fact that we humans evolved from apes, so why are our physical strength getting worse and worse in the evolution of human beings for thousands of years? The main reasons for this are as follows.

First, we now have more help from science and technology. First of all, the first example is that we are now a development of human beings, with the help of more science and technology, we are now doing anything, using, such a machine we can, for example, our brick moving machinery, building buildings using tower cranes, anyway, it is the use of a variety of tools to complete, basically now the machine has replaced our labor. Therefore, the control of our human strength is getting smaller and smaller, and the training of our muscles is also getting smaller and smaller.

To a certain extent, the muscles of the face are getting smaller and smaller, and the strength in our bodies is also decreasing. <>

Second, there is also the fact that one of our current personalities is becoming more and more lazy. There is also a personality of people who are becoming more and more lazy, because in such an era, the economic development of our time, people are more and more dependent on the care of others, so it is in this situation of dependence on others that we people are born of a kind of inertia. <>

3. Many people are reluctant to engage in physical exercise. Finally, there is a very real problem, that is, more and more people are not willing to engage in physical exercise. Because some people feel that physical exercise is very tiring, such a tiring activity is a very uncomfortable situation for themselves, so they are reluctant to go.

Human beings survive by mental intelligence, and physical strength is not a necessary indicator of survival, so they slowly evolved.

Humanity has been purified from a physical exertionist to a mental evolutionary. They turn their tools into things they make themselves

Because the human body is used in and out. In other words, the more the body moves, the more the body functions will improve. If you don't exercise for a long time, your body will decline.

Human beings don't need much physical labor in modern society. A lot of things use machines to help humans do their jobs. I don't have that much strength to work, so people's physical strength is much worse than before, which is normal.
