New Ancient Human Lineage Discovered in Colombia Through DNA Sequencing

New Ancient Human Lineage Discovered in Colombia Through DNA Sequencing
……………….

Scientists in Colombia have identified a previously unknown lineage of ancient humans through full genome sequencing of 6,000-year-old remains excavated near Bogotá, Reuters reported. The group, named the Checua after the excavation site in Nemocón municipality, represents a distinct genetic line not previously recorded in the Americas.

Led by Dr. Andrea Casas from the National University’s Genetics Institute, the research compared Checua DNA with samples from other parts of the Americas. The findings revealed that individuals from the Cundiboyacense plateau during the Pre-ceramic Period carried unique genetic markers, suggesting the Checua formed an isolated lineage.

The study included partial remains of approximately 30 individuals, with six genomes sequenced in full. Unlike other remains from the region—which share genetic links to populations migrating through Central America—the Checua show no known descendants and may have been a nomadic hunter-gatherer group that eventually died out due to environmental or health factors.

Anthropologist Dr. José Vicente Rodríguez noted that a well-preserved Checua skull displayed an elongated shape and signs of dental infection, offering further insight into their health and diet. Researchers believe volcanic activity may have influenced their reliance on root vegetables. The study is ongoing, with scientists hopeful that future discoveries will provide more clarity on the Checua lineage.
