Scientists Sequence Y Chromosome DNA of Denisovans and Neanderthals 0

- September 29, 2020
The genomes of our closest relatives, Neanderthals and Denisovans, have been sequenced and compared with that of modern humans. However, most archaic individuals with high-quality sequences available have been female. In new research, a team of geneticists from the United States, China and Europe has sequenced the paternally inherited Y chromosomes from three Neanderthals and two Denisovans; comparisons with archaic and modern human Y chromosomes indicated that, similar to the maternally inherited mitochondrial DNA (mtDNA), the human and Neanderthal Y chromosomes were more closely related to each other compared with the Denisovan Y chromosome; this result supports the conclusion that interbreeding between early Homo sapiens and Neanderthals replaced the more ancient Denisovian-like Y chromosome and mitochondria in Neanderthals.
