Today's pop science story is the new finding of ancient footsteps in new mexico which appear to be older than we expected.
From my understanding, archeologist/historians are still waiting for further evidence that these footsteps are indeed as old as we think they are. What steps are currently being taken to verify this find? are they still doing e.g. radiocarbon analysis?
Second, if this finding indeed appears to be real, how does this impact current theories? Would we need to find a new migration path for these earlier settlers? Does this invalidate other theories about how humans entered america?

Here's another that looks at the question from the point of view of indigenous people. There are no answers as of when I posted this, but this one could be interesting:
