Too bad for your little fantasy, there was NO "White" first wave. Craniometric studies on PaleoIndian remains have ONLY shown affinities to Asian, Pacific, & Native American populations. DNA studies on PaleoIndians matches them to modern Native Americans. DNA (& linguistic) studies on modern Native Americans say they've been here 20-40,000 yrs. Try reading scientific journal articles on the subject (special attention to Powell & Neves' "Cranifacial Morphology of the First Americans" which proved that prior & highly disputed claims of "Caucasoid" PaleoIndians were due entirely to suspiciously consistant OBSERVER ERROR on the part of a small handfull of White scientists, or the Powell & Neves study on Kennewick Man which conclusively found he was NOT Caucasoid, let alone Caucasian). BTW, if you're thinking of Ainu.... think again, they SOLIDLY match Asians in DNA & linguistic studies. SOME craniometric studies purport minor Caucasian affinities, but ALSO match them just as close to Melanesians & Polyesians & Australian Aborigines.
