I've looked at many Wikipedia articles, but there seems to be a gap in human evolution. Homo sapiens is presumed to have originated in Africa about 200,000 years ago. What were its African companions at the time? It was supposed to have evolved from Heidelberg, but these seemed to have died out around 300,000 years ago. Other species at the time (Neanderthal, Denisovan, Erectus) were in Europe or Asia, but not in Africa.
