This is very cool. A team of researchers have observed E. Coli bacteria for over 40,000 generations and have been able to observe spontaneous, adaptive mutations (a.k.a.: evolution) of the samples. While this doesn’t prove evolution, it is an excellent example of good science. From what I can tell, the experiment was quite rigorous, with samples being kept from about every 500 generations or so. As I said, very cool.
