Abstract
Denisovans are an extinct hominin group defined by ancient genomes of
Middle to Late Pleistocene fossils from southern Siberia. Although
genomic evidence suggests their widespread distribution throughout
eastern Asia and possibly Oceania, so far only a few fossils from the
Altai and Tibet are confidently identified molecularly as Denisovan. We identified a hominin mandible (Penghu 1) from Taiwan (10,000 to 70,000
years ago or 130,000 to 190,000 years ago) as belonging to a male
Denisovan by applying ancient protein analysis. We retrieved 4241 amino
acid residues and identified two Denisovan-specific variants. The
increased fossil sample of Denisovans demonstrates their wider
distribution, including warm and humid regions, as well as their shared distinct robust dentognathic traits that markedly contrast with their
sister group, Neanderthals.
Very interesting. Thanks. The dating is confusing. I
even looked at some of the popular press accounts to
see if there might have been some clarification
(sometimes a principal investigator is interviewed)
but I didn't see anything useful.
