One tiny cell built inside of itself a new pigment, a brilliant green thanks to its ability to absorb only certain colors in the light of a younger, weaker Sun. The pigment – dubbed chlorophyll by animals that rely on this one cell’s innumerable descendants to power name-giving brains – channeled the energy in sunshine to split the waters of Earth’s early oceans. The cell took in carbon dioxide, paired it with once watery hydrogen, and made food. In the process out bubbled a flammable gas that made life as we know it possible: oxygen.
