What will happen to the appearance of human beings in 100 years?

Some scientists speculate that in the future, the appearance of human beings will continue to evolve and change.

In 100 years, the human head may be bigger because the human brain is getting smarter.

It is true that human beings are still evolving, but the appearance of human beings should not change again.

Personally, I don't think there will be a big change in appearance, it should be similar to what it is now.

100 years can change habits, but not looks.

I feel like it's going to get taller, and the mouth is getting smaller and smaller and chewing less.

I think it will change as the environment changes, but we don't know exactly what it will do.

I don't think there will be a big change in this, but the current form is still relatively good.

It shouldn't change much, after all, human evolution is complete.

I think it's a big difference, after all, it's constantly evolving.

Accumulated knowledge is like compound interest. It starts slowly and small, but it grows over time, and the longer it goes, the faster it grows.

The Zhizhi people have amassed more than 200,000 years of knowledge, and about 10,000 years ago with the invention of agriculture and the resulting necessity for fixed cities, this rate began to really pick up. Population growth, writing, and the invention of the printing press spread more information faster, and it really began to compound. Electronics have overdriven communications, and it has been soaring for the past 100 years.

Think about it. In 1800, the fastest means of transportation by land was horseback. 170 years later, we landed a man on the moon.

In 1923, we thought the universe consisted of a galaxy that was bent to a galaxy, the Milky Way. In 1924, we discovered many other galaxies far away. A few years ago, astronomers aimed the Hubble telescope at the emptiest, darkest part of space they could find and left the blinds open for 10 days.

The result is an astonishing image of thousands of galaxies. And they have been going on. We're just beginning to understand how big the universe is.

Hubble Deep Field. It was a day of miracles and miracles. Nianji.

Big head. Because the direction of human evolution is intelligence, and the brain will continue to develop, so in 100 years, the appearance of human beings will evolve into a large brain.

It should still be about the same as now, because 100 years is not a long time, and the evolutionary changes are not obvious.

I think 100 years from now, human beings will still look like this. Not much has changed. Because human evolution has reached its limits.

What will humanity look like in 1 million years? or no longer a living being, but has evolved into a cyborg biomorph.

Humanity in 100 years will be different from now.

First, the physical aspect may be weakened.

Second, the brain has become stronger. It is estimated that a lot of brains will be developed.

Third, there may be some variations, which will be found in the future of biological genetic technology.

Fourth, the psychological aspect has also become mechanical, that is, the human self-consciousness may become less and less obvious.

Fifth, at the same time, the technology of the human world will be quite advanced at that time, beyond the solar system, and it is estimated that the galaxy will be gradually explored.

Sixth, there are many artificial intelligence and other machines, some of which we can't imagine.

1. Economy.

Whatever happens after 20 years of economic development, everything is possible. First, if the current situation in Asia continues, China's GDP will more than quadruple, and China's leadership over the world economy will become increasingly apparent. The Middle East will be depleted by the depletion of oil resources, and eventually the current situation of some poor countries in Africa will emerge.

North Korea may have some economic development after the peaceful resolution of the North Korean nuclear issue, but the outlook is not promising.

Outside of Asia, there is also the potential for dramatic change. Of course, the United States will rely on its strong economy to dominate the world, but as the world economy develops, this situation may be broken by China and the European Union, forming a three-legged situation. Australia will always be plagued by an ageing population, which is a big obstacle to Australia's development.

Africa's economy will depend on Africa's labor force to develop, but the overall situation will not change much.

2. Culture. The development of world culture will become impossible with the development of the economy, but with the continuous development of modern communication technology, the differences between world cultures will gradually decrease, but the cultural characteristics of various countries and regions still exist, which is also a major premise for the tourism industry to continue to be high.

Modern culture feels like it's the same day and of course it will still be 20 years from now. However, the generation and spread of these popular factors will become simpler, automated, faster and more popular due to the development of science and technology and economy, and everyone will have a strong cultural atmosphere. At that time, the textbooks would be very different from those now, and there would be more and more things to talk about modern high science, and the scope would be more and more extensive, especially the primary school textbooks.

One more point: the rapid development of network technology will bring infinite vitality to the cultural life of the people of the world.

3. Society. Under the constraints of the United States, there will not be much change in the world society, and on the whole it will remain a situation of antagonism between capitalism and socialism, but there will be a certain degree of relaxation and mutual accommodation between the two. Different regions are affected by the economy and culture, and the social security situation may become more peaceful and harmonious, or it may become more chaotic.

Generally speaking, China's social system will not change much, but prices will be greatly affected by the development of Chinese politics. The situation in which the renminbi is constantly appreciating under the constraints of the United States will be broken, and the exchange rate is likely to fall from the current level to more than 10, but this is beneficial to the people's lives.

Theoretically, there will not be an increase in the number of socialist countries in the world, but the policies of many capitalist countries will gradually move closer to socialism, which will provide China with great opportunities for exchanges.

4. Environment. The damage to the environment caused by human development will intensify year by year, the level of desertification in the world will be further increased, and the area of the Sahara Desert will expand by 5 to 10, which will make many African countries face overall desertification.

In China, the state will carry out a series of environmental remediation and invest a lot of money. However, these remediations will not bring substantial results, and environmental degradation is still very serious. More and more species will become extinct in the world, especially in China, and air quality will decline step by step, which is the alarm bell that nature is sounding again and again to human beings.

What would humanity become if it could continue to develop for another 1 million years?
