Excavating. Time dating, Fossils and determination of DNA sequences are the tools to study Human evolution.
-Humans are a single species. Even though there is a vast diversity through out the world.
- All humans come from Africa. The earliest members of the human species Homo Sapiens can be traced there. Our genetic footprints can be traced back to our African roots.
