How did the ancestors of mankind come from?

There are two concepts about the origin of human ancestors.

The Origin of Primitive Man The view that the ancestors of Primitive Man originated from African ape-man about 7 million to 5 million years ago is not controversial in academic circles at present. For example, in 2009, Science magazine published an article saying that fragmentary primitive human fossils found in Ethiopia were successfully pieced together into a female primitive human skeleton. Scientists say that the ape-man named "Aldis" lived about 4.4 million years ago, one million years earlier than another female primitive human skeleton "Lucy" found earlier in Ethiopia, and it is the earliest primitive human skeleton so far.

But there are two hypotheses about the origin of modern people.

At present, many scientists support the theory of African origin, that is, Africa is the hometown of modern people.

A few scientists support the theory of multiple origins, that is, modern people originated in Europe, Asia and Africa.

Extended data:

According to genetic research, it is speculated that human ancestors branched off from chimpanzees about 5 million years ago and developed independently. As early as 65 million years ago, primates differentiated from other mammals. So in the evolution of primates, the origin of human beings can be said to be the latest thing.
