Elizabeth Liddle- Ignorant of Natural Selection
Earth to Elizabeth: Natural selection is blind and without purpose. It doesn't do anything and yes it is a result:
“Natural selection is the result of differences in survival and reproduction among individuals of a population that vary in one or more heritable traits.” Page 11 “Biology: Concepts and Applications” Starr fifth edition
“Natural selection is the blind watchmaker, blind because it does not see ahead, does not plan consequences, has no purpose in view.” Dawkins in “The Blind Watchmaker”
“Natural selection is the simple result of variation, differential reproduction, and heredity—it is mindless and mechanistic.”- UC Berkley on Evolution
Natural selection- The process by which in every generation individuals of lower fitness are removed from the population- Mayr "What Evolution Is"
The first step in selection, the production of genetic variation, is almost exclusively a chance phenomenon except that the nature of the changes at a given locus is strongly constrained. Chance also plays an important role even at the second step, the process of elimination of less fit individuals. Chance may be particularly important in the haphazard survival during periods of mass extinction. IbidOoops there's that darn word "chance"
