In order for evolution to take place, we need natural selection and, as of right now, we don't have that. At least not to a large extent (see Darwin Awards).
Our medical technology has advanced to the point where diseases and disabilities (such as asthma and scoliosis) that would normally have prevented people from reproducing are treatable to the point where those genes continually get passed on. This not only applies to physiological attributes but mental ones as well.
With the possible exception of extreme retardation (which usually has little to do with genetics and is more often caused by other external factors) even people that would be considered slow or have conditions such as Bi-polar disorder or Schizophrenia, more often than not, can reproduce. If the smartest and strongest person in the world has just as much of a chance of reproducing as a sickly and slow person, evolution pretty much goes out the window.
I'm not saying that any of this is bad, but it does put a hamper on the evolution of our species. Basically, at this point, the evolution of our technology has to replace the physical evolution of our race.
So, basically this.
