Document Summary

What were the implications of darwin"s theory (5)? everything is related the earth is probably really old: populations/species change over time extinction is common all the crazy adaptations can be explained by natural processes. Holes in his theory, biological changes, molecular level. how evolution took place (the physical forces that change the way species appear) and dna. Genetical theory of natural selection was one of r. a. fisher"s major works. It describe the nature of inheritance and dominance. Genotype combination of alleles for an individual. Phenotype observable physical and behavioral characteristics of an organism. Fitness differential effect on the reproductive success of an individual in comparison with other individuals in the population. Explain the debate between darwin and intelligent design. Intelligent design was introduced in 1989 in of pandas and people because creationism was ruled unconstitutional in 1987: replacement of creationism" with intelligent design". The belief that a supernatural force created all life, the earth, and the universe.

Darwin was not the first to consider evolution as a process but he did come up with the first effective explanation for how it happens. Describe Darwin's theory of evolution by natural selection. Explain how this theory was a major advance over prior ideas as to how organisms changed over time. Give evidence in support of evolution and describe the driving forces for evolutionary change.

QUESTION 3

Which of the following would NOT be a good method for sortingout the evolutionary relationships between a parrot, gorilla,hippopotamus, starfish, and catfish?

		comparing the skeletal anatomy
		examining the habitat in which these organisms live
		looking at embryos for common developmental patterns
		comparing the nucleotide sequence divergence of selectedgenes
		all of the above would provide useful information

QUESTION 4

		Hawaiian islands
		Amazonian rainforest basin
		Mississippi river

QUESTION 5

Darwin's concept of evolution "the theory of descent withmodification through variation and natural selection" can bedemonstrated by which of the following examples?

		A giraffe stretches his neck to reach higher branches. Theexercise of stretching up strengthens the muscles in the neck andlegs. This ability to stretch is also seen in the giraffe'soffspring.
		A monkey accidently drops her fruit in the salty water of a bay,she recovers the fruit and eats it. She discovers that the fruit iscleaner and tastes better after it has been in the salty water. Shecontinues to wash fruit in the bay before eating. Her offspring seewhat she has done and also wash their fruit in the salty water.Soon the whole population is washing their fruit
		Several turtles hatch from a clutch of eggs buried in the sandon a beach. One of the turtles is the color of the sand, the othersare darker in color. The turtles all scurry to the water, but oneby one the dark turtles are eaten by birds, only the sand coloredturtle survives. When it enters the water the sand color changes toa darker brown. The turtle grows, mates and has offspring that arealso sand colored when they are born
		A female alligator gives birth to a male alligator that has theability to change color to a bright white when it is in cold water.The baby male alligator is quickly spotted by a large bird of preyand eaten

10 points

QUESTION 6

During the Beagle journey, Darwin visited islands,allowing him to compare island species with continental species. Interms of framing his theory of evolution, why was thissignificant?

		Because the island species had both similarities to theircontinental ancestors and unique adaptations to their islandenvironments
		Because the island species no longer shared traits with theircontinental ancestors
		Because the species he saw on the islands had not changed fromtheir ancestral continental form
		Because the island species had very low reproductive andsurvival rates as compared with their continental ancestors
