This shed some new light on some of the earliest inhabitants of North America and the migration patterns they may have followed. The man was part of the ancient Saqqaq culture, which lived in Greenland between 2500BC and 800BC.
What is most amazing to me is that he or his ancestors traveled from Eastern Siberia across the North American Continent to Greenland. It makes me wonder what could have prompted such a long and difficult migration. It also goes to show that our ancestry could be much more varied than we tend to think. If this man could travel half-way around the world 4500 years ago, imagine the diversity that has happened since then due to migration and cultural upheaval.
