Only the bible! This is the book with the largest circulation in the world. This is the inspiration of the creator to mankind. This is a book about the origin and destination of life. Please read it carefully. Every living thing has its own genetic factors, and each factor is made up of millions of atoms, which must be seen with an ultra-micro microscope. This discovery (which Darwin didn't know at that time) can even show the wonders of the creator's behavior. If all the human genetic factors in the world are put together, I'm afraid it's not as big as a needle tip! But it can have the characteristics of ancestors, and retain everyone's psychological characteristics, ruling all creatures on the ground! This is really an interesting example, which shows that there is no other hypothesis to explain this law except from a wise God.
