Charles Darwin introduced the idea that species could evolve and split into separate lineages, referring to it as "specification" in his 1859 book "On the Origin of Species". It was not until 1906 that the modern term "speciation" was coined by the biologist Orator F. Cook. Darwin, in his 1859 publication, focused primarily on the changes that can occur within a species, and less on how species may divide into two. It is almost universally accepted that Darwin's book did not directly address its title. Darwin instead saw speciation as occurring by species entering new ecological niches.
