How is it that Africa is the only place where humans started out at? They just found some bones in a dry area that preserved them. For all we know humans came from Sweden.
That has long been my question too. Just because the oldest bones found (to date) have been in Africa, doesn’t mean that man originated in Africa.
Probably the most compelling evidence for “Out of Africa” is the similarity between human DNA and chimpanzee and gorilla DNA.
Gorillas and chimpanzees are found only in southern and central Africa, which is the same place where all of the earliest (150,000 to 200,000 years ago) Homo Sapien fossils are found.
Some scientists believe that an earlier hominid - Homo Erectus (about 2 million years ago) - may have developed in Asia, then migrated to east Africa, then may have evolved into Homo Sapiens.
But most scientists believe that Homo Erectus evolved first in Africa, and then migrated to Asia.
There are some near-human ancestors, like Neanderthals (about 300,000 to 40,000 years ago), who quite clearly did not evolve in Africa.
Neanderthal fossils and tools are only found spread across Europe, the Middle East, and Asia.
