I have to say we have changed sence the earlier times... I cannot possibly give you dates, and graphs without years of studying just this question, but think about it. In the beginning of time, people were really just like animals, then they began to wear clothes, eat with a fork, and "evolve". Today we drive cars, attend school, and are "domesticated". We have definitely evolved from the time of driving horse drawn wagons, to today...but be it better or worse would need another discussion.
Well, this is not necessarily the result of evolution, but rather of the accumulation of knowledge. I know more about astronomy than Galileo ever did, but this is probably not because I'm smarter than him. This seems to be confirmed by the fact that I can't paint better than Michelangelo or write better poetry than Dante; and by the fact that I have never actually discovered anything new facts in astronomy myself.
