Domasticated hominins?

The usual story.
Homo sapiens tribes migrate from Africa, and they drestroyed other human species, as Homo erectus, denisovans, neanderthal, red deer humans and homo florensis.
What if a creative tribe enslaving them. For example.
They can teach of Asian homo erectus populations or neanderthal to bear burdens or tool-making.
Ideas?
How could have been done so that the Neolithic Revolution?
 
There's no traces whatsoever of genocidal slaughter of Neanderthalians, tough.
As for Homo Erectus, poor guys went extinct before Homo Sapiens appeared, except in Indonesia.

Of course, giving their degree of sophistication, Neanderthalians and Erectus would probably more "enslaved" than "domesticated" in your scenario (even if, again, we have no traces of really widespread cohabitation between these species).
Hell, Homo Sapiens inherited a lot of their technological features from these two species, we're not talking about beast to be tamed there.
