Creationist critics get their comeuppance

from Short Sharp Science -
A couple of weeks ago we reported on the work of Richard Lenski, who has spent much of the last 20 years maintaining cultures of E. coli to see how they evolve. His paper describes how one of his populations evolved the ability to metabolise citrate, something E. coli cannot do by definition.

It's one of the most dramatic examples of evolution in action ever seen, and because Lenski freezes samples of the population every 500 generations, it is possible to go back and track how the ability developed. Lenski and his team are now doing so, and hope to have a detailed history of the ability developing, mutation by mutation.
