There is a unique trait in dental orientation, exclusive to mammals (if I am not mistaken, thought it might be primates), that can first be found in the Therapsid Reptiles. Anthropologists have been able to trace this dental orientation. After that, someone with far more knowledge in the field can fill in.

I am a bit clearer when tracing back. The proper classification of humans is (at this point I believe) is Homo sapiens sapiens. Now I am sure you are familiar with Neanderthals. These hominid species is properly classified as Homo sapiens neaderthalensis They were a very closely related species, in fact humans were capable of interbreeding with them. That means they shared genetic traits, otherwise interbreeding would not have worked. This means there needed to be a common ancestor. This was Homo heidelbergensis. Its fossils were first discovered in 1907 (after Darwin had died). The fossil record also supports that H. heidelbergensis came from H. ergaster and H. erectus. Both were discovered after Darwin's death. Those were predated by H. habilis (also post Darwin) then there is also the Australipithicines. The later part of human evolution is well documented.
