Looking at just that few 1000 years of human natural selection , now add many cycles of changing envirionments that will force change thru the glacial periods, continental drift adding to this radical plant evolution, alterring atmosphere concentration.

When you start having that "1000 yard stare" instead of just flicker of a timid glance at earth's changing landscape & major events that would create so many adaptations with natural selection in full force thru it all. Look at the drift of the continents then ask yourself how many interglacial episodes did the earth experience? Just the last glacial period 25k yrs ago, found ice sheets over most of North America & profoundly impacted Earth's climate, causing drought, desertification, and a dramatic drop in sea levels with dramatic changes to mammal habitat.
