Human sperm cells with flagella (under a microscope) About two billion years ago, the first eukaryote cells evolved from the earlier prokaryote cells. These eukaryote cells also evolved a new way to move themselves around. Even though some eukaryote cells have flagella that look like the ones in prokaryote cells, they don't work the same [...]

Bacterium with a flagellum(under a microscope) The simplest cells, developing about four billion years ago, had no way to control their own movement. They lived in the oceans, and they floated wherever the water took them. Sometimes they found food there, and sometimes they didn't. Many cells still live this way. By around [...]
