1) Evolution a. is always progressive and directional towards perfection b. three of the processes of evolution are random in the change of allele frequencies over time c. natural selection selects for (or against) traits that affect reproductive fitness d. all of the above e. b and c only 2) Speciation a. generally takes place when populations are in separate environments b. generally takes place when gene drift is stopped between populations c. is a rare and unusual event in the history of life on earth d. all of the above 3) How does evolution explain the diversity of life on earth? a. adaptive radiation shows how related species evolve and adapt in new or empty enviornments b. the pattern of speciation and extinction observed for life on earth provides a lot opportunities for diversity of life c. environment change promotes diversity through speciation and extinction 4) Specialized versus Generalized species a. humans are one of the most specialized species on earth b. humans are one of the most generalized species on earth c. cockroaches are one of the most specialized species on earth d. koala bears (which eat only eucalyptus leaves) are one of the most generalized species on earth 5) The evolution of new species comes about from an interaction of all of the following, EXCEPT a. genetic variation b. gene flow c. natural selection d. environmental change 6) The origin of life and evolutionary theory a. evolutionary theory cannot explain the origin of life b. evolutionary theory is the foundation for the explanation of the origin of life c. evolutionary theory explains change of life over time, not the origin of life d. a and c only 7) The earth and life on earth a. the age of the earth is roughly 10,000 years old, and the earliest life is 6,000 years old b. the age of the earth is roughly 4.5 billion years old, and the earliest life is 3.7 billion years old c. the age of the earth is roughly 4.5 million years old, and the earliest life is 1.7 million years old d. none of the above 8) The different types of evidence to study whale evolution includes all of the following, EXCEPT a. embroyo studies b. intelligent design c. DNA/molecular studies d. fossil record e. vestigial traits 9) All of the following are the three themes that are important to remember regarding the history of life on earth, EXCEPT a. we are the dominant species, and we have a very long evolutionary history b. we are the dominant species, but we have a small, fairly recent evolutionary history c. the only real origin has been of the universe, the rest is a rearrangement of what existed d. each event which has lead to us, could have turned out differently
