Hello

There is a theory on the sucess of the steppe people's conquest and colonization of Europe that atributes it to the transmision of disease (Yersinia pestis), along with military and technologic superiority (the horses). Suposedly, the horse warriors would be behind the plague , who would take on the survivors and rule over them and intermarriage.

If this is so, can we equate these events with the conquest and colonization of the Americas by the Europeans?
The euros brought disease aswell to the indigenous americans and rule over the weak remnants, giving their blood and language to them.
North Euros are more Yamnaya, while South Euros are more Neolithic Farmer.

Excluding the existence of a third racial group (African slaves), would Southern Europeans be an analogy for Mesomamericans (whose natives still exist and fared better)? And Northern Europeans be an analogy for South/North Americans, whose ancestry derive mostly from European colonists?
