Oceanographer Penny Chisholm introduces us to an amazing little being: Prochlorococcus, the most abundant photosynthetic species on the planet. A marine microbe that has existed for millions of years, Prochlorococcus wasn't discovered until the mid-1980s -- but its ancient genetic code may hold clues to how we can reduce our dependence on fossil fuels.

This talk was presented at an official TED conference, and was featured by our editors on the home page.
