New genome-wide ancient DNA data is being utilized to revise the history of the peopling of Central and South America. This history of migratory patterns in the Americas has long been the focus of archeogeneticists, geneticists, and biologists of many different fields. The history is constantly being revised as new date presents itself. Now, new genome-wide ancient DNA data has being utilized by an international research team to revise the history of the peopling of Central and South America.
Many recent studies have come to the same conclusion as this particular study, which involves co-senior author David Reich. The researchers involved used DNA from 49 individuals from Central and Southern America. Their DNA suggests that within the ancestral lineage of migrants that originally populated these areas there are two previously unknown migrant lineages. One of these migrants waves was displaced by a new wave of migrants 9 kya. The descendants of these new migrants are very closely related to peoples in modern who are located in the same region.
Additionally, the study found that certain groups of individuals in Central and South America were closely related to the Clovis peoples who were mainly located in North America. Prior to this, it was not known that Clovis peoples had succeeded in spreading beyond North America.
