The clearest proofs is that the vast majority of the genetic code of all living things, with only a few exceptions, is by no means a coincidence! So we can stuff human genes into E. coli cells and make them express human proteins. If you find an exception, let me know and let's make a fortune together! The fusion of life can reach the point where you have me and I have you. Our eukaryotes are likely to be produced by an archaea phagocytosing a bacterium, and plant cells are produced by engulfing another photosynthetic bacteria. Such ancient devouring has formed a stable symbiotic relationship, and no one is needed.
In addition to this intracellular symbiosis, we telemarketing list also coexist with many microorganisms to have a healthy body, because we also have to use each other's genes to do some dirty work for ourselves that we don't want to do by ourselves. Life on earth is an inextricably intertwined "net of heaven and earth". If we look at our bodies again, we need to be organized in a very orderly manner. "Organize" is both a verb and a noun. Various molecules make up cells and then tissues and organs. Unlike plastic, all the cells in our body are constantly replacing many molecules.
Biochemical molecules don’t just come in and come in—all of them come in, they will be full, and they will come out. Even in a lifetime, most of the atoms in the body will be replaced with new ones. Is the "I" still the original "I"? It's like the "ship of Theseus", if the wood on Theseus's ship is gradually replaced until all the wood is not the original wood, is the ship still the original ship? ? For all living things, this is not a matter of thought that occurs in the head, but a real thing. And life, because of this flow, reduces its own entropy (order) by increasing the entropy (disorder) of the universe without violating the second law of thermodynamics.
