if we take a generation to be 20 years, and the grown children move 20 miles away so as not to compete for resources and/or find fresh ones, then we get about 1 mile per year. 1000 years == 1000 miles of migration,
Typical mobility numbers for North American lithic and archaic groups are in the hundreds of miles/kilometers annually, generally decreasing over time. Those estimates come from groups many thousands of years after the dates being discussed here, but they're the best we have.
So: I estimated 365 miles/year and you had "hundreds of miles/kilometers annually." I don't see anything to argue about, specifically, especially no one really knows.
Your response above is 1 mi/year, but in any case I'm not really responding to argue. Just stating what a reasonable mobility is in North American archaeology, around ~500km/yr.
