Study from the University of Chicago suggests that humans are still evolving. One argument I've heard often is that we're no longer evolving because we've taken the "danger" out living. To put it unkindly (but generally repeating the argument): the sick, crippled, and those with mental problems are now integrated into society and not "weeded out" by nature. This conceit is more common that I'd expect. The problem with it is that it emphasizes the phrase "survival of the fittest" (not Darwin's) over the theory's emphasis on species' interactions with their environment. I don't think that evolution can be described as a simple clearing out of the lame; that overly simplifies the role of environment and the concept of biological fitness.

This /. poster expresses the concept somewhat more concretely.
