Taiwanese and Japanese researchers conducted isotopic analyses of a Denisovan sample codenamed Penghu-3. This tibia fragment was discovered at the bottom of the Taiwan Strait.
Scientists were able to date the remains of this ancient human species for the first time using radiocarbon dating. In addition to dating, specialists studied the ratio of nitrogen and carbon isotopes.
According to the analysis results, the individual's diet primarily consisted of terrestrial animal meat. It was also established that he lived in an area characterized by the predominance of open landscapes. Information about these findings is presented in a preprint posted on bioRxiv.org.
