On the contrary, the average 2-year child is "smarter" than the "smartest" of any other animal. So indeed humans have evolved intelligence to a tremendous degree. Of course there's a lot of variability in the population, and the very definition of "genius" is based on that variability - something like the top 1/100 of 1% as measured by IQ. It doesn't matter how smart the average person is - by definition there can never be more than that number of geniuses.
