The way relatedness is determined is based on genetic similarity.
Older methods that used more superficial traits are no longer current because they weren't based on a good understanding of relatedness.
There is no 'Caucasoid species' and the peoples of the Americas and Eurasia are part of the same genetic grouping that includes people from East Africa.
Haplogroups M and N are associated with Western and Eastern Eurasians, both are derived from L3 which originates in East Africa. Based on this, yes, all not-Africans trace (the bulk of) their ancestry to one population group within Africa.
