Actually while the haplogroups and genetics of greater mesoamerica are broadly proto-northeast asian, genetic studies of the peoples of ancient siberia, languages and patrilineal genetics reveal a diverse number of origins for the peoples of the pre-colombian americas.
For example a tentative link has been established between the Na-dene languages and the Yeneseian languages of the Yenesei river, in western Siberia, the first transberingian link (besides the links between aleut peoples and peoples of siberia but they don't count because they cheat going across frozen polar ice and shit).
Genetic studies of proto-siberian peoples 20,000 years ago have found that a migration of proto-europeans mixed into these peoples by eastward migration, one possible theory is that this left archaic european markings in native genetics.
Other genetic studies have suggested the Iroquois have the neolithic anatolian haplogroup, indicating the 'solutrean' theory of peoples migrating northwards during the period where the ice age wasn't as much coldrape but was still cold enough that the north atlantic ice sheets allowed primitive anatolian tribes 20,000 years ago to expand into europe, and from there into the homelands of the Iroquois in the northeast of the americas.
There is also a speculative (but unconclusive) link between uncontacted tribes in the amazon, and archaic aboriginal DNA, indicating that it is possible stinky monkey people from australia once spread across the east Asian seaboard into the americas 50-100,000 years ago across Beringia, being gradually displaced by the expansions of east asian and siberian peoples who came later.
More recent speculative colonization waves may have come from polynesian seafarers, the lost fleet of Mali in Africa, Welsh explorers searching for new land for their sheep and possibly Carthaginian expeditions.
