Steven Gollmer Cedarville University Env. Systems: Page 2 Classification System Kingdom (Monera, Protista, Plantae, Fungi, Animalia) Phylum (Chordata) Class (Mammalia) Order (Proboscidea) Family (Elephantidae) Genus (Loxodonta) Species (africana)

Steven Gollmer Cedarville University Env. Systems: Page 3 Natural Selection More offspring produced than those that survive to reproductive age. Heritable variation exists among members of each species. Best adapted to get resources most likely to produce progeny. Each species becomes well adapted to reproducing in its environment. Change in environment may select for other features. Isolated populations diverge when placed under different selective pressures.
