North America's Yukon was home to humans thousands of years ago than previously thought
A new research by Anthropologists from the University of Montreal has suggested that the first humans to arrive in North America may have migrated thousands of years earlier than previously thought by researchers.

The research that has been published in the journal Plos One has determined that humans lived in what is now Yukon, Canada as early as 24,000 years before present. The previous estimate had put this number at 14,000.

For research, the researchers examined about 36,000 bone fragments found in the Bluefish Caves. Bluefish Caves is an archaeological site located in Yukon that was first excavated in 1977.

The researchers have found human traces on at least 15 of the bones that were recovered from the site. The most prominent of the traces include tool markings on a horse mandible – a historically certain proof of presence of human activity.

"With advances in that, it became much more obvious which bones had been modified by the tools found on the site," Travel + Leisure quoted an author of the study that was conducted.

The research has also pointed out to various other traits of the people living at that time. These traits include a nomadic lifestyle and living in caves rather than a proper settlement.

The early humans that would have lived during this time were known as the Beringia (because they had crossed the Bering Strait). Anthropologists have assumed that the Beringia would have migrated via the landmass that once connected Siberia and present-day Alaska. But their genetic growth was limited because they were unable to move south for thousands of years due to the ice age.

The lack of early human traces in this region can also be because of the fact that many of the areas where the Beringia people once lived are now underwater.
