Researchers track evolution through snapshots of 40,000 generations

    A follow-up report on the E coli speciation event reported in 2008. The team has gone back to preserved samples from every 500 generations, and genetically sequenced them to identify the points at which new mutations arose, and at which point those mutations started becoming predominant in the population.

    Still an open question regarding all of the steps that went on - as discussed at the end of the article, citrate-eating genes by themselves don't result in efficient citrate eating. Something else not yet understood is going on, too! More work to do!

    Ahh I remember this one. Nice.

    But don't forget: no one was watching the speciation in the interim when they weren't taking those 40,000 samples of citrate transport evolution. Science has no answer for what occurred within those intervals, or however infinitesimal an interval creationists will try to point to.
