24,000-Year-Old Butchered Bones Found in Canada Change Known History of North America

24,000-Year-Old Butchered Bones Found in Canada Change Known History of North America

(Read the article on one page)

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.

A hallmark of the toolkit associated with the Clovis culture is the distinctively shaped, fluted stone spear point, known as the Clovis point. These Clovis points were from the Rummells-Maske Cache Site, Iowa

However, the recent discovery of bones in Canada that show distinctive cut marks supports the perspective that there were other inhabitants of America that preceded the Clovis.

The finding was made in the Bluefish Caves in Yukon, which consists of three small caves that are now considered to hold the oldest archaeological evidence in North America.  Researchers have found the bones of mammoths, horses, bison, caribou, wolves, foxes, antelope, bear, lion, birds and fish, many of which exhibit butchering marks made by stone tools.

The site was first excavated by archaeologist Jacques Cinq-Mars between 1977–87, and initial dating suggested an age of 25,000 before present.  This was dismissed at the time as it did not fit with the well-established Clovis-First theory. However, a new study published in the journal PLOS One supports the initial dating, demonstrating that humans occupied the site as early as 24,000 years ago.

As part of the study, the research team analysed 36,000 mammal bones found in the caves. Carnivore tooth marks were observed on 38 to 56% of the bone material. A total of fifteen bone samples with cultural modifications confidently attributable to human activities were identified, while twenty more samples with “probable” cultural modifications were also found. “The traces identified on these bones are clearly not the result of climato-edaphic factors or carnivore activity,” the researchers report. “The presence of multiple, straight and parallel marks with internal microstriations observed on both specimens eliminates carnivores as potential agents.”

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.”

Fantastic!  I love it when the OLD DOGMA is upset by new evidence!  And I strongly suspect human exploration and habitation of North America goes far beyond 24 kya which will upset the old dogma even more. 

 

This happened because in Canada they are “Allowed” to dig past the level of the imaginary “Stop Sign”.

It's not about Dogma. It's about evidence. What you call dogma is actually just what is supported by actual solid evidence.. Until there is solid evidence that contradicts and points somewhere else (such as that talked about in this story) you are relying on guesswork and / or fantasy.

I agree that human habitation likely goes back even further than this though. Because I find it highly unlikely anyone has been fortunate enough to find the absolute earliest evidence that's out there (and that's even if there is evidence still existing for the earliest people). Sooner or later someone will find something from a time even earlier than talked about in this story.

Same thing is true when the earliest use of fire by humans is talked about. It's continually pushed back earlier and earlier with new discoveries.

Funny thing about “Hard Evidence”...In the end it is also just Speculation and Conjecture based on Thesis derived from just a few rare fragments found. It is all still just “Best Guess”.

Funny thing about "accepted" evidence that IS dogma. There is a big book out by Cremo I believe; "Unconventional Archeology" if I remember correctly which has several evidences of early high tech(relatively)and evidence of modern humans much "earlier" than so called scientists were/are willing to accept so these evidences are suppressed, discredited or disappear so they will not upset or discredit the "accepted" dogma. That is NOT science! It is nothing but protecting what some few people are willing to accept.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
