It is so good that you have clarified the importance of Africa at this time. There have been so many reports claiming that this or that fossil finding changed the story of human origins and even some who declare the “out of Africa” theory is now no longer valid. We need to push the dates back much earlier, yes, but it does not change the fundamental African origin of archaic Homo varieties. Also, given the widespread genetic evidence of “ghost” archaics, not just Neanderthals and Denisovans, contributing to modern human genomes, it is possible to consider not a great proliferation of separate species, but rather of subspecies. If this makes of Homo erectus and its descendants appear for a time to be a typical polytypic but single species, it would be less confusing for those outside the field.
