I don't know. But you're looking at a long distance inland, 100 miles or so, before they would get to caves to do art in. |
The objection has been that people living in the far north couldn't have gotten across the Atlantic because they didn't have boats; that they didn't venture out into the ocean ice. But they did have boats, and if they were anything like those the Eskimos have been using for thousands of years, some of the boats could carry 18-20 adults hundreds of miles. |
You get three boats loaded up like this and you would have a viable population. You could actually get a whole bunch of people washing up on Nova Scotia. |
