Thank goodness for global warming.
I always like the word “may” in the title.
They walked north from the many several hundred thousand year old sites in South America.
Glacial ice keeps beer cold longer and I don’t know why.
I have to believe that people were here long before 13,000 years ago. Them NOT being here makes little sense when you consider people were just about every other place.
Well duh! I personally figured this out long ago. Sea levels were way down during the “ice age” so most of the coastal settlements they made are now under water. You think they came across the “Bering Land Bridge”? OK, then what? The area between the Brooks Range and the Alaska Range was probably not glaciated but everything else was so you come across from Asia and face walls of ice as you move inland. Keeping to the coast is the only viable means of travel.
If only there had been some man made climate change to melt those massive sheets of ice
Somewhere in the GGG archives should be an article about the narrow land bridge being the hunting grounds of Saber-tooth cats which decimated migrating populations for centuries.
We will probably never find boat artifacts that can prove this one way or the other.
From memory, the oldest identifiable boats are less than 3,000 years old.
Also, the Pacific coast of western North America 10,000-20,000 years ago has been under water for thousands of years after the glaciers melted, which has wiped out almost every trace of human artifacts.
