"he models found that between 229 and 300 people were in the original group, which led to the final estimate of 250 people, the researchers said. This number is so small, it would have created a "genetic bottleneck," meaning there was little genetic variation associated with the first major migration wave into the Americas, Fagundes said.

However, so much time has passed since that original group arrived in the Americas, that Native Americans as a whole have had time to recover their genetic diversity through new genetic mutations, he noted. Moreover, some Native Americans in North America formed unions with people from later migrations, which also increased genetic diversity, Fagundes said."

Fascinating article. One of the amazing things about DNA is how it enables to track migrations and origins.
