Bones in Yukon Cave Show Humans in North America 24,000 Years Ago
A close look at bones found in a Yukon cave seems to confirm a controversial finding made decades ago, archaeologists say: that humans arrived in North America 10,000 years earlier than many experts believe.
The bones are the remains of horse, bison, mammoths, and other Ice Age fauna, originally excavated from the Bluefish Caves near the border of Alaska and the Yukon Territory in the 1970s and 1980s.
Back then, radiocarbon dating placed the bones at about 25, 000 years old not in itself surprising, except that many of the bones appeared to have been butchered by humans. And the earliest evidence of human activity on the continent at least at the time dated back a mere 14,000 years.
"At least two of the bones betray the tell-tale signs of human butchery" Anthropologist Lauriane Bourgeon at the University of Montreal said, including the pelvis bone of a caribou that bore deep, parallel lines etched in them.
That is typically the mark of a stone tool used to de-flesh or disarticulate a carcass, .
