Thanks for the feedback! That may have just been a misunderstanding on my part. Are you referring to the "and now", here?
Older settlements have been found in Chile, and now, also in North America.
The article didn't mention any pre-Clovis settlements (or I missed the mention) in N. America, so I assumed this was the first. I can remove that "and now" if there were already others.
The Clovis part was a small portion of the article. I'm not well informed on the topic, but my impression from that article was that the idea of Clovis people as the first humans in North America was already out of favor before this find, and this is just more evidence to the contrary. The main thrust of this article was the claim that people migrated to mid-latitude N. America before the opening of an ice-free corridor, which happened about 14,800 years ago, implying that they must have done it by boat.
