"The analysis also paints a picture of humans as a far more diverse collection of species and sub-populations than exists today. Between 200,000 and 400,000 years ago, our own ancestors lived alongside a primitive human species called Homo naledi, found in southern Africa, a larger brained species called Homo heidelbergensis in central Africa and perhaps myriad other humans yet to be discovered."

David: Comment: It is a strange thought to imagine various types of humans evolving everywhere from their ape-like ancestors, all to end up as one surviving type. Sounds like a purposeful drive. A major problem is the paucity of wide-spread homo fossils to fill in the story.

Tony: Sounds like the scattering at Babel. Within a few generations the dominant morphological traits of the group would be pretty much set. It would also explain a lot of other non-biological mysteries.

David: To reach one cohesive phenotype, there would have to be inter group cross breeding. How does that happen if they are scattered into small enclaves?

Tony: Trade, most likely.
