There's no evidence that, on the genetic level, that humans are evolving at all. We are a remarkable similar species as far as our DNA is concerned.
However, we are evolving in terms of intelligence. Contrary to the curmudgeons, we are getting smarter at about the rate of 3 IQ points per decade.
What's driving this? Technology is doing so, but only indirectly. It seems that exposure to culture in general and language in particular is what shapes our brains and makes us 'human'.
