Descent with modification we've defined evolution as descent with modification from a common ancestor, but exactly what has been modified? Partly influenced by an essay on the principle of population (1798) by thomas robert malthus, darwin noted that population growth would lead to a struggle for existence in which favourable variations prevailed as others perished.
A patterns of descent with modification showed that all organisms came from a single ancestor which through the passing of time and after different variations have birthed to a new species that will also tend to bring new divergent species.
