24,000-Year-Old Butchered Bones Found in Canada Change Known History of North America—April Holloway, Ancient Origins, about Earliest Human Presence in North America Dated to the Last Glacial Maximum: New Radiocarbon Dates from Bluefish Caves, Canada—Lauriane Bourgeon , Ariane Burke, Thomas Higham
Archaeologists have found a set of butchered bones dating back 24,000 years in Bluefish Caves, Yukon, Canada, which are the oldest signs of human habitation ever discovered in North America. Until recently, it was believed that the culture that represented the continent’s first inhabitants was the Clovis culture. However, the discovery of the butchered bones challenges that theory, providing evidence that human occupation preceded the arrival of the Clovis people by as much as 10,000 years.
For decades, it has been believed that the first Americans crossed the Bering Strait from Siberia about 14,000 years ago and quickly colonized North America. Artifacts from these ancient settlers, who have been named the Clovis culture after one of the archaeological sites in Clovis, New Mexico, have been found from Canada to the edges of North America.
The findings support the hypothesis that prior to populating the Americas, the ancestors of Native Americans spent considerable time isolated in a Beringian refuge during the Last Glacial Maximum [LGM], the last period in the Earth’s climate history during the last glacial period when ice sheets were at their greatest extension. As the researchers of the study concluded:
“In addition to proving that Bluefish Caves is the oldest known archaeological site in North America, the results offer archaeological support for the “Beringian standstill hypothesis”, which proposes that a genetically isolated human population persisted in Beringia during the LGM and dispersed from there to North and South America during the post-LGM period.”
