If gene flow ends, allele frequencies in isolated populations are free to diverge meaning that the population begins to evolve independently of each other. If mutation, selection and genetic drift cause isolated populations to diverge sufficiently, distinct types, or species, form speciation takes place. Speciation splitting event that creates two or more distinct species from a single ancestral group: when speciation is complete, a new branch has been added to tree of life. Species an evolutionary independent population or group of populations whose members have the potential to interbreed with one another to produce viable, fertile offspring. Subspecies populations that live in discrete geographical areas and have distinguishing features such as coloration/calls but are not considered distinct enough to be called separate morphospecies. Interbreed to breed with individuals of another species, subspecies or variety: dogs interbreed with wolves.
