Speciation provides a framework for classifying biodiversity on Earth and is a central concept in evolutionary biology. Speciation refers to the origin of new species. It occurs by mutation, isolation and selection. For speciation to occur, two new populations must be formed from one original population, and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed.
