History of theory of Evolution begins with two issues
a) theory of “fixity of species” needed to be refuted. b) animals classified not by evolution nor DNA
· Classification of living things: Linnaeus · role of fossils: Cuvier · Buffon challenges fixity of species · Hutton introduces change with time regarding geology · Malthus: struggle for existence · Lamarck: Acquired characteristics and use and disuse · Darwin · Mendel · Role of DNA and Heredity · Role of DNA and evolution
