Bear Bones Recast Japan’s Ancient Past, Debunking Ushikawa Man
New CT scans show the Ushikawa bones thought to be ancient humans are actually brown bear remains, pushing Japan’s oldest mainland human fossils to about 14,000–17,000 years ago (with Ryukyu Islands finds possibly around 32,000 years). The study, published in Anthropological Science and led by Tokyo researchers, demonstrates how modern imaging can correct past misidentifications and reshape our view of Japan’s prehistoric timeline.
