Human Evolution is Accelerating

According to statistical studies of the human genome, the rate of evolution among humans -- measured as the rate at which new gene alleles become prevalent in the population -- is now about 100 times what it was during most of the past 6 million years. The biggest driver of the acceleration is growing population; bigger population equals more mutations and thus more chance for a very good one to appear.
