Newly excavated tools suggest humans lived in North America at least 30,000 years ago

People could have come across the land bridge 13.5K years ago.
But there was already civilization in South America 30K plus years ago.

So from where did the Inuit, coastal, and plains natives come from? and how did they cross? If you watched sesame street when you were a kid you would be singing "one of these things ain't like the other" right about now

I took anth101 in 1998?
At that time the Fagan etc all discounted the Land Bridge theory. Mount Verde was discovered in 1975 and ended the Clovis first theory for good and illustrated that an advanced culture had inhabited South America prior to the end of Ice Age.
How could people have come across the Land Bridge and walked all the way to South America and started a culture?
The Americas were peopled by sea. Maritime migration.

DOn't bet on it. There is a good chance there was at least one land bridge or at least a series of close together islands between NA and Europe.
