I remember a DNA study that was done a couple of years back that was trying to “prove” the land bridge theory by comparing the mitochondrial DNA of native new worlders from South America, Central America, West Coast of North America all the way up to Alaska, in the hopes that they could establish a linear link of DNA all the way back to Siberian natives. But they could not. IIRC, they established that the closest link to South American natives’ DNA was to people from TAIWAN!...........
