The human body doesn't need to evolve any further in order to increase the probability of survival. We've overcome our physical limitations through science and medicine, and are now keeping people alive who wouldn't have survived 1,000 years ago, or 100 years ago, or even 10 years ago.

The evolution of the human brain is an entirely different phenomenon. That evolution, mental rather than physical, is obviously still going on, and our brains will continue to evolve, forever, long after, just like the Neanderthals, all the Fox News viewers, whatever species they are, have all died out.
