Evolution in a Bottle
For those that don't know, quietly, behind the scenes, Richard Lenski and his team have been conducting one of the most important experiments in evolutionary biology in a few beakers in their lab for the last 20 years.
Lenski is a prominent name in the field and very well respected, he's done some amazing work and had a hand in Michigan State Universities DevoLab - (AVIDA) the evolution simulator I've linked t in several threads: http://devolab.cse.msu.edu/software/avida/
Anyway, about 20 years ago they put some E.coli in a few flasks, and have been watching what happens to them in this new environment - they've been evolving now for 44,000 generations. They figured it should spur selection and adaptation. It has. In one of these beakers, the bateria have quit eating the sugar they've been feeding them, and started chowing down on the media used to dissolve that sugar - what's more, these new bacteria reproduce 75% faster than the original stains.
