However, unlike Malthus and Paley, Darwin did not agree that it was God who implemented these checks, which inspired Darwin to move away from natural theologian explanations, and instead form his own ideology on natural selection Darwin, , pp. To begin with, Darwin argued that all species came from a common ancestor, and he described this by comparing it to the tree of life. This metaphor suggested that every species come from a common root, and eventually break off in branches, and in turn each of these branches break off into more and more branches; suggesting that each branch is a different species, and this is how different species can be very similar to one another, because they all come from the same branch and same root Darwin, , pp.
