US EditionDNA sequencing of ancient remains by Colombian scientists reveals unknown human lineage
Analysis of DNA from six individuals reveals a unique ancient lineage without known descendants, enhancing understanding of early human migration in the Americas, researchers said.
- Scientists in Colombia discovered a previously unknown human lineage by fully sequencing ancient remains near Bogota, adding complete genomes from six Checua group individuals to the project.
- The Checua, named for Nemocon municipality, consist of partial remains from some 30 people and one mostly intact skull, belonging to a population about 6,000 years old.
- Anatomical analysis shows the Checua skull is more elongated than others and exhibits abscesses on the front upper jaw, indicating tooth loss to infection, Dr. Jose Vicente Rodriguez noted.
- Researchers say the group may have been a nomadic hunter-gatherer community with no known descendants; Dr. Andrea Casas said, `We work with the remains that are available`.
- Other remains excavated between 1987 and 2003 shared genetics with Panama, indicating migration from the Bering Strait 20,000 years ago, while Dr. Andrea Casas said `we found individuals from the Pre-ceramic Period here have a lineage that hasn't been reported`.
