Can single-celled organisms evolve into multicellular organisms now?

This question is very interesting, the answer is possible, but we may not feel this change.

We know that evolution is not magic, it takes hundreds of thousands or even hundreds of millions of years, and the time span is very large. The life of each of us is only a short existence in the long river of history. It is difficult for us to observe evolutionary changes in such a short time. And there are many single-celled organisms, which are found all over the world. We don't know the situation around them, and it is impossible to observe the changes taking place inside them.

I suspect that Darwin's theory of evolution may be wrong.

Why evolution?

Some people think that the early earth environment was bad, from single cell to multi-cell, from lower animals to higher animals, from marine life to land life, but in the end it broke through the barriers, overcame difficulties and realized the diversity of life on earth today.

Today, human science and technology still cannot accurately predict weather, earthquakes and so on. And we can't understand things now, but we input the state of the earth many years ago as the conclusion after "scientific research" into textbooks! It should be said that this is entirely to cater to Darwin's theory of evolution and preconceived what the early earth should look like. Finally, there is a conclusion! Needless to say, the fatal flaw of evolution. What species looked like when they first appeared, and what they still look like now. If the theory of evolution is correct, it is universally applicable to any species. Only apes can't evolve into adults. Other animals older than humans can also evolve their civilization, even before humans! However, at least for now, there is no such discovery!

Today, it is worrying that the earth environment on which we live has been destroyed beyond recognition by evil human beings, as well as wars and internecine wars caused by playing politics, nuclear threats, poverty, sexual and drug abuse, over-exploitation, all kinds of pollution, childlessness and self-destruction! If this was the case in the early days of the earth, species appeared in this situation, species can survive and continue to this day, and evolution is so small. . . Possibility! Ultimate wisdom didn't arrange this!

The oneness of the environment can determine the size of a species population. The evolution of species needs the diversity of environment. The current environment is complex and changeable, and even the living environment of single-celled organisms is affected. Whether the species can survive continuously is a big problem.

The evolution of single-celled species requires temperature and food. On earth, only volcanoes located in the depths can provide enough energy. As for survival. Where there are volcanoes, the environment has been fixed for tens of thousands of years. But also formed a stable ecological circle.

Finally, it takes a long time for a single cell to evolve into a multicell. No one needs to explain how powerful human creativity is. Maybe 50 years later, there will be no place on earth where no one can live. Evolutionary single-celled organisms have long been human specimens. In short, unless human beings do not harm the existing form of the earth and maintain biodiversity.

There is a situation you are talking about, that is, the pathogenic bacteria of the human body. I believe that with the development of science and technology, it will definitely evolve into a multicellular organism. And can rapidly evolve with the animal body.
