Ancient DNA shows European wipe-out of early Americans

“Surprisingly, none of the genetic lineages we found in almost 100 ancient humans were present, or showed evidence of descendants, in today’s Indigenous populations,” says joint lead author Dr Bastien Llamas, Senior Research Associate with ACAD. “This separation appears to have been established as early as 9000 years ago and was completely unexpected, so we examined many demographic scenarios to try and explain the pattern.”
“The only scenario that fit our observations was that shortly after the initial #colonisation, #populations were established that subsequently stayed geographically isolated from one another, and that a major portion of these populations later became extinct following European contact. This closely matches the historical reports of a major demographic collapse immediately after the Spaniards arrived in the late 1400s.”
