And another would be the thousands of years of human accelelerated
co-evolution in these agricultural ecologies. I mean, yow, oats originated
as a weed of wheat...
I recently ran across the theory that creosote bush successfully invaded N.
America an estimated 14K years ago. Now it covers a big piece of the
continent. So sometimes these invasions happen without human intervention.
