entropic_existence: George Burns: Haven't humans somehow halted or artificially altered the course of evolution?
Simply put? No, we haven't. This is a common misconception and you'll even see some biologists uttering it but it couldn't be further from the truth. Have we changed our fitness landscape with modern medicine and all that? Certainly. But there is still natural selection going on, we have just managed to alter those selective constraints. One could actually argue that because of modern medicine we now have more raw material for evolution in the human population. Genetic variants that would have been lethal 50 years ago (killed you before you reproduced) may not be now, this allows humans, as a population, to explore deeper "fitness valleys". Compensatory mutations may then turn these negative traits into net positives down the road, we really can't predict anything about the path evolution will take.
So no, all we have done is altered what is important and visible to natural selection through our ingenuity and shifted the emphasis of natural selection, not removed it from the picture.
