Extinction in lab bottle was a fluke, experiment finds

Sometimes extinction is just a fluke, a long-term experiment in evolution has shown.

Scientists captured an extinction in a bottle during a 27-year-long study in evolutionary biologist Richard Lenski’s lab at Michigan State University in East Lansing. Researchers there have been growing 12 flasks containing Escherichia coli bacteria. Those bacteria have been evolving for more than 60,000 generations.
