The experiment is irrelevant and if it was carried out again it would not necessarily result in the same mutation happening again. The bottom line is that he has the bacteria that can digest citrate. These are from a species that could not use citrate. Thus they have evolved.
@wttmartin9 The experiment is not irrelevant because it was carried out multiple times. There were 12 replicate populations (all descended from a single cell) that have all been evolving independently of one another in separate flasks. Part of the uniqueness of his experiment was that you can see the repeatability of evolution and how things might differ if you were to re-wind the tape of life and play it again as Stephen Jay Gould phrased it.
I know this sounds harsh but unless this Lenskis experiment can be repeated, which could have easily been done with a double blind controlled experiment it cannot be regarded a empirical.
Very hard to read slides. Perhaps someone would be willing to edit in screen shots?

@benthemiester E. coli is easily available. Get started. Should only take about 20 years or so.

Oh man, that translation sub-text is a bit random at times! (Shows up particularly when he's reading from the slides).
