good point - of course I absolutely believe humans (as well as every other living thing on Earth) as still evolving. And of course evolution happens all the time, with every generation evolution must be happening. And I've written genetic algorithms to find solutions to problems so I know that evolution is not intrinsically a slow process.

My point really was that evolutionary changes in these time-scales are very unlikey to significantly affect society (changing to agriculture etc).

Thanks for the response and the great links!
