Evidence for earliest Humans in North America

I just read a fascinating new archaeology article providing evidence for humans in North America  (Alaska/Beringia) at 24,000 years before present.

I’m not familiar with the journal, PLOS, because it is outside of my field, but the research and argument look pretty strong.

Two general ideas flow from this. One is the possibility that humans were in North American but limited to the northwestern-most corner for thousands of years, before breaking through and settling the rest of the continent. But, this also gives support for other pre-Clovis finds elsewhere in North and South America, and the idea that humans had spread widely well before the traditionally cited 13,000 before present mark.
