Nevertheless, most scientists hold that the first organisms on Earth were much like bacteria of today. But several features of the biochemistry of life suggest that bacteria arenât so ancient after all. In fact, in some respects, the cells of our own bodies tell us more about the evolution of life than bacteria do.
