The Tri-Human World: I need some help with this timeline...

This map is from my timeline: The Tri-Human World. In short, 3 humanoid species---Homo Erectus (Blue), Homo Sapiens (Red), and Homo Neandertalasis (Yellow)--don't go extinct and stayed in their own territories:

What do you think happens next for this timeline?
 
Is there a reason that large swaths of the map is colored green, a color that you have not associated with any of the different human species? I can only assume that this is uninhabited by humans, is inhabited by multiple humen species or is inhabited by a different human species not mentioned earlier.

In this world will there be continum of human geneology? As in mixing between different populations.
 
This should be moved to ASB, it is an evolutionary POD.

Homo Sapiens would probably wipe the other two out through war, competition, and interbreeding. That is was happened to Neanderthals IOTL, and Homo Erectus has the same disadvantages against homo sapiens that Neanderthals had, with none of their advantages. Do to the nature of Homo Sapien compared to other early hominids, it is incredibly unlikely for any hominids aside from us to survive very long with us around.

Edit: This should really go in ASB, because that is the only way Homosapiens will stay in their homeland. There is literallly no reason for them to not go out into the world.

I think this set up is going to age very poorly within the next decade with advances in modern genetics. Take for example the discovery of Denisovans, of which we have only two small fossil specimens but a huge base of genetic evidence. Also there is a newer species we learned about through fossil excavations on the Indonesian island of Flores called "Hobbits" or Homo floresiensis that was essentially an island dwarf species of Erecti. None of this is your fault, the field is just moving very rapidly at this point.

The genes that allow us to use advanced stone tool industry predate the divergence of Human ethnic populations, but arose after the divergence with Neanderthals which predated the divergence from Erecti. But advanced stone tool industry didn't arise until well after most Human ethnic populations had diverged from each other (about 50kya). This means either that your Humans use advanced stone tools but decided to stay in southern Africa, they have the potential to use advanced stone tools but never developed them, they don't have the ability to use advanced stone tools (evolutionary POD which belongs in ASB), your Humans do use advanced stone tools but so do the others (also an evolutionary POD).

The fossil record shows Erecti died out 140kya, their last refuge was in eastern Asia, which I think means they were out competed by the Denisovans (a relative of Neanderthals), who were in turn out competed by Humans. Personally, I don't think the survival of any of these species are evolutionary PODs, but the site staff may feel differently.
