I have an assignment where I have been researching from Ardipithecus ramidus onward. I have to determine species time frame, significant first find information, and habitat details for 9 different species. I'm on the last one 'Homo sapiens sapiens' and am having some trouble finding resources that don't conflict with one another. My text is telling me that Homo sapiens neandertalensis was from about 125 - 30 kya, and that anatomically modern populations are from 30 kya onward (roughly). Now when I look for Homo Sapiens first find info from other sources, I am getting some drastically different dates. Can anyone help me clarify what I'm looking for? I know that I am supposed to be finding dig sites in both Africa and France.
