a : descent with modification from preexisting species : cumulative inherited alter inside a populace of organisms by means of time leading to the looks of latest varieties : the method by which new species or populations of living things establish from preexisting varieties by successive generations also : the scientific principle explaining the looks of recent species and kinds through the motion of various biological mechanisms (as all-natural range, genetic mutation or drift, and hybridization) Due to the fact 1950, developments in molecular biology have had a growing affect on the theory of evolution. —

The idea starts with the premise that within a population, You can find variation in features, for instance beak form in one of several Galapagos finches Darwin researched.
