An article published in the journal “Nature” reports the results of the sequencing of DNA found in the sediments of the Denisova Cave, in Siberia. A team of researchers achieved the largest sequencing ever conducted on genomes recovered from sediments from a single site with 728 samples. The results offer a picture of the occupation of that cave over a period of more than 300,000 years by three human species: the Denisovans, the Neanderthals, and the Homo sapiens. However, most of the samples turned out to be DNA from various animals, which is also useful because it offers information on the connection between humans and the species that various populations ate.
