Humans are still evolving even though modern housing and sanitation, medical science and a rich and varied diet appear to have largely insulated much of the population from the lifeordeath. We're absolutely still evolving. Just in the last couple thousand years, our jaws have receded, we have had less hair, and have gotten much taller. In a billion years, the human species will be well nigh unrecognizable and will have long since diverged into many other species. In other words, the population is evolving. Though the evidence is clear that human evolution is continuing to play out around the world, we still know very little about exactly how it works.

There is no doubt that we are a product of millions of years of evolution. But thanks to modern technology and medicine, we miss Darwins law of survival of the fittest. If natural selection is the basic mechanism behind evolution as proposed by Darwin, and if human beings are deeply immersed in what we call culture, the question is: are we still evolving.
