Many researchers have supposed that the emergence of life hinged on a sequence of improbable events, at the same time as they have taken for granted the ability of life on earth to persist indefinitely and to "freeze in" the consequences of early accidents. Smith argues that there is ample evidence for a different interpretation: the emergence of life was an inevitable outcome of geochemistry on the early earth, and the same forces responsible for emergence have continued to support the persistence of life ever since.
