A genetic mutation results in the offspring of two butterflies being a different color. There is no evidence of biological evolution in this.
In populations of organisms, biological evolution is the change in hereditary features through successive generations. When diversity is added to a population through gene mutation or genetic recombination or removed by natural selection or genetic drift, features undergo evolutionary alteration. the gradual genetic change within a population. What is the most likely outcome if two species rejoin after many generations if allopatric speciation has place after a population split into two different populations?
