Hot springs in Yellowstone are home to some of the most primitive microbes on Earth. Researchers suspect that life may have begun 4 billion years ago in near-boiling water.

Scientists suspect that prebiological molecules became organized into cycles of chemical reactions that could sustain themselves independently. A group of molecules would fashion more copies of itself by grabbing other molecules that surrounded it. There may have been many separate chemical cycles at work on the early earth. If they used the same building blocks to compete their cycles, they would have competed with one another. The most efficient cycle would have outstripped the less efficient ones. Before biological evolution, in other words, there was chemical evolution ~ page 104
