Carmel (Israel) has a sedimentary sequence which represents the type section for about the last 800,000 years in the Levant.Those artifacts are the oldest of their kind found in northern Eurasia and representative of something previously unexplored: Denisovan culture.At this point, says Douka, we cannot definitively say that Denisovans created those items, though the evidence is pointing that way. is a University of Victoria professor and Paleolithic archeologist who specializes in the origins of art and symbol use and wasn’t a part of these recent papers.For a long time, nobody knew exactly how long this cave was occupied and the nature of the interactions of the hominins living there.But now, the studies collectively reveal that humans occupied the cave from approximately 200,000 years ago to 50,000 years ago.

What’s novel in the new studies, Nowell says, is that “we know virtually nothing about who Denisovans were, so every study like this one helps to enrich our understanding of their place in the human story.”“Given that we have items of personal adornment associated with Neanderthals and modern humans all around the same date as the ones thought to be associated with the Denisovans,” she adds, “I would find it more surprising if they were not making similar objects.”These particular items, Nowell explains, especially the tooth pendant, likely speak to “issues of personal identity and group belonging.” The teeth were purposefully chosen, modified, and worn — standing as jewelry that communicates something about both the wearer and likely influenced how the wearer felt about themselves.In the more recent layers of the cave, between 55,200 to 84,100 years old, only Denisovan remains were found.
