Sexual selection arises from interspecies cross breeding. By this time, and largely in response to geological and biological evidence he had accumulated in South America, Darwin was formulating his theory of natural selection, although it was not to appear in print untilwith the publication of On the Origin of Species.

A bacterium can give rise to millions of new bacteria in a single day it produced by binary fission. The beneficial variations help the organisms to survive while the harmful variations hinder and handicap the organisms for survival.
