Checua

Checua is a preceramic open area archaeological site in Nemocón, Cundinamarca, Colombia. The site is located 7 kilometres (4.3 mi) north of the town centre. At Checua, thousands of stone and bone tools, stone flakes and human remains have been found, indicating human occupation from around 8500 to 3000 years BP. A prominent archaeologist for Checua is Ana María Groot, who published the results of her research in 1992. In August 2025, it was reported that human remains from the area dated to about 6000 years BP which had their genome fully sequenced for the first time, represented a previously unknown human lineage, with no known descendants.
