EVOLUTION

SCOPES TRIAL A court case in 1925, that pitted John Scopes against the State of Tennessee. It was illegal to teach evolution in a state funded school. This trial changed that.

TAXONOMY Classification of Organisms: “King Philip Came Over From Greece Speedily” Kingdom Phylum Class Order Family Genus Species
4
SPECIES A species is the most specific of the categories. It is often applied arbitrarily. Some think that different breeds of dogs should be called different species. However, the various breeds of dogs are a result of humans intervening and manipulating the selection of specific traits.
5
SPECIES CONTINUED In nature species prefer their own kind but sometimes interbreed with closely related animals if there is not a viable mate. “Coywolf” A horse and a donkey can mate resulting in a mule but the mule cannot reproduce. Hence, the horse and donkey are of different species.
6
ALTRUISM The behavior of an animal that benefits their species at their own expense. Bee stings invader to protect the nest but it dies.
7
EVOLUTION EVIDENCE Natural Selection – environmental pressures force the survival of the fittest due to the most advantageous genes and traits surviving and reproducing. Speciation – The formation of a new and distinct species through the process of evolution. Fossil records – some transitional fossils and DNA links
8
OPPONENTS OF EVOLUTION The fossil record is void of transitional fossils and organisms appear whole without transitional fossils. Spontaneous Generation – the idea that life came from nonliving things. Law of Biogenesis – only life begets life.
