Natural selection observed in a lab

In the 1980s, Richard Lenski hypothesized that his research team should be able to watch random mutations and natural selection taking place in a lab by observing a bacteria population over many generations. In 1988, beginning with a single bacterium, he started several replicate colonies. Recently, after 33,127 generations, his team has observed natural selection.
