If evolution is correct
The modern evolutionary theory believes that all existing organisms on the earth are those primitive beings that evolved over a long period, and in the process of evolution, due to the existence of genetic mutations, organisms will undergo some subtle changes from time to time in the process of reproduction from generation to generation. If some changes are conducive to better survival and reproduction, then these changes will pass the test of "natural selection" and be preserved and passed on from generation to generation, while the other way around, they will be eliminated by "natural selection".

Nuclear fusion ends in iron
An atom is composed of a nucleus and electrons, while a nucleus is composed of neutrons and protons. For an atom, the number of protons in its nucleus determines the type of element it is, for example, hydrogen with atomic number 1 has only one proton in its nucleus, helium with atomic number 2 has two protons in its nucleus, and so on for other elements.
