Haplogroup R&Q originated in tandem from the Baikal area, and both haplogroups moved into Europe westwards and Americas eastwards.
The European native Q almost got washed out but still exists, whereas the American R got washed out, and is the haplogroup that obtained the genetic conehead inbreeding trait after the younger dryas caused a bottle neck and founder effect among the survivors in peru.
When parts of this culture moved west into the Maghreb, it became the Osiris cult and spawned the Atlas/Atlantis myth.
Geneaologists intentionally obfuscate the fact that R&Q were present in both Americas and Europe, because the nitpicky details easily point towards an eastern and western branch of BOTH, as opposed to a clean split between R&Q.
tldr;
R&Q emerged BEFORE the migration into americas and Europe, but stayed together in both populations until one washed out the other in respective continents.
