This isn't true. Inuits have occupied northern Alaska for centuries. They
lived along the pack ice capturing seals, even in the winter. And there
were lots of Native Americans living in very cold parts of Canada during
the winter. And the Siberian tribes like the Gilyaks, Tungis and others
lived in Siberia year round. They didn't need our labs. Their technology
was very good for creating warmth.
