Most of life’s life’s genetic diversity is turning up in bacteria and archaea. A single quart of seawater can hold 60,000 different kinds of bacteria — more than 10 times all the species of mammals on Earth. And the differences among those bacteria are not superficial. A greater genetic distance than the one that divides us from duckweed may separate two bacteria that look nearly identical.
