Evolution is a process that explains how organisms have diversified and descended from earlier forms of organisms over time. Essentially that means all species living on earth have derived from a common ancestor. Speciation is an evolutionary process that leads to the formation of a new species. Natural Selection and Speciation For a new species to form, individuals of a population need to be reproductively isolated from one another.
Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book The Origin of Species. He also identified sexual selection as a likely mechanism, but found it problematic. There are four geographic modes of
