Prof. Kaifu Yousuke is a biological anthropologist specialising in human evolution in Asia. Born in 1969, he was educated at the University of Tokyo (BSc, 1992; MSc, 1994) and received his DSc in 1999 from the same university. As a professor at The University Museum, University of Tokyo, Kaifu studies fossils of Homo erectus, Homo floresiensis, other archaic hominins, and early modern humans, with a focus on evolutionary changes, human biological diversity, and developments in humanity. He often works with specialists from other research fields, such as archaeology, primatology, and Quaternary science, to contribute diverse inter-disciplinary perspectives on human evolutionary histories and behavioural changes. From 2016 to 2019, when he was a researcher at the National Museum of Nature and Science, Tokyo, Kaifu carried out an experimental voyage project to unravel the mysteries of Palaeolithic voyaging in East Asia.
