The team redated the remains, remeasured the skulls and extracted DNA.
Their work, presented by Fehren-Schmitz at the SAA meeting, paints a complicated picture of Lauricocha.
To gauge whether the Lauricocha residents were descended from members of more than one migration, the team sequenced the DNA from their mitochondria, cellular organelles that are passed directly from mother to child, and thus trace maternal ancestry.
All five people were found to be descended from maternal lines that are common among modern and ancient indigenous people of North and South America.
South American prehistory, it seems, is about to get a lot more complicated.Ancient South American genomes may also show how humans adapted to the New World.In a separate study, Fehren-Schmitz and his colleagues looked at a gene variant that protects against altitude sickness.Later researchers dated remains from Lauricocha closer to 5,000 years old, greatly diminishing its appeal for researchers interested in the early prehistory of South America. Nobody was interested any more,” says Lars Fehren-Schmitz, a biological anthropologist at the University of California, Santa Cruz.More than half a century after the site’s discovery, Fehren-Schmitz’s team got permission to look at five human skeletons excavated from Lauricocha and held at the National Museum of the Archaeology, Anthropology and History of Peru in Lima.
