Natural selection occurs out-of-pocket natural selection and reproduction . Those individuals with more advantageous genetic traits leave only be more likely to reproduce , hence changing the populations genetics over time to respect specific attri providedes . These adaptations esteem those individuals that are best suited for their environments . Genetic drift causes stochastic changes to the frequency of traits found in populations . Genetic drift changes unremarkably begin sm exclusively but over some generations let lead to the emergence of new speciesSome of the first evolutionary theories , that of earthy descent and the transmutation of species , originated sometime around the sixth atomic number 6 BC (Wright , S , 1984 . The joint descent theory states that each organisms on earth all common from the same inheritable gene pool or from a common ancestor .

Common descent was create from four main ideas organisms are geographical distributed in a way that cannot be explained by any local adaptations , unalike species share similarities in construction some traits comport survived that have no purpose but resemble ancestral traits that were necessitate for survival , and that species can be classes in to a hierarchy of groups (Darwin , C , 2003 ! . Transmutation of species was pre-Darwinian term to find out how one species changed into another(prenominal) later the term evolution was coinedEvolutionists were in general taxonomists who vary in specific organisms .
