What has a genome, manifests metabolic processes (alive) and is 3.5 billion years old?

They reproduce by fission, so it is not possible to distinguish a mother from a daughter cell. Doubling time in laboratory culture is about twenty minutes, which implies that death rate once they colonise all of the available medium.
