(Phys.org)—A team of researchers with members from Russia, Germany, Canada and Italy studying a tooth found in Denisova cave back in 1984 has found that it belonged to a young Denisovan girl and that it was a baby tooth. In their paper published on the open access site Science Advances, the team also notes that DNA evidence suggests the girl lived approximately 20,000 years before other Denisovans living in the same cave who also left behind fossils that have been found and identified.
