Ancient DNA suggests tie to Native Americans
NEW YORK — The DNA of a baby boy buried in Montana 12,600 years ago was recovered, and it provides new indications of the ancient roots of today’s American Indians and other native peoples of the Americas.
It’s the oldest genome ever recovered from the New World. Artifacts found with the body show the boy was part of the Clovis culture, which existed in North America from about 13,000 years ago to about 12,600 years ago and is named for an archaeological site near Clovis, N.M.
The boy’s genome showed his people were direct ancestors of many of today’s native peoples in the Americas, researchers said. He was more closely related to those in Central and South America than to those in Canada. The reason for that difference isn’t clear, scientists said.
The researchers said they had no Native American DNA from the United States available for comparison, but they assume the results would be same, with some Native Americans being direct descendants and others also closely related.
The DNA also indicates the boy’s ancestors came from Asia, supporting the standard idea of ancient migration to the Americas by way of a land bridge that disappeared long ago.
The burial site, northeast of Livingston, Mont., is the only burial known from the Clovis culture. The boy was between 1 year and 18 months old when he died of an unknown cause.
He was buried with 125 artifacts, including spear points and elk antler tools. Some were evidently ritual objects or heirlooms.
