Here is a very good article on some neat studies in evolution. We have been able to observe the results of evolution for quite a while, and we have also been able to examine microevolution, or the change in gene frequencies in a population, for a fair amount of time. But only recently have we begun to correlate specific mutations and groups of mutations with their evolutionary function at higher levels (like, say, social behavior) and that is REALLY exciting. Kudos to the author for giving a suitably sophisticated treatment of a complex subject.
