They did this by genetically modifying how the bacteria digests its food, and then putting them in a tank with very little food - sugar - and a lot of carbon dioxide. In only a few hundred generations, these bacteria evolved to feed on the carbon dioxide in the air instead. Amalia Thomas reports...
