 E. Wallace discovered natural selection after Darwin
Which of the following defines Lamarckism?
 A. The idea that those structures that are used more are inherited and vice versa
 B. The idea that the less change there is between two organisms' DNA, the less time has passed since they diverged
 C. The idea that individuals who inherit beneficial traits survive and reproduce more, leading an accumulation of favorable traits
 D. The idea that as organisms progress in complexity, evolution slows
 E. The idea that God created all of the structures needed in man and that these structures are unchanging through time
Which of the following phenotypes would be considered an adaptation? One that...
 A. ...results in sexual dimorphism

Pacu fish and humans have similar-looking teeth. Why isn't this evidence of common ancestry?
 A. This is an example of gradualism, whereby the teeth have gradually changed to be more like humans since humans are the smartest organisms on earth
 B. This is an example of convergent evolution - similar environment, but different ancestry
 C. They are used to consume different types of foods
 D. The embryos of these two organisms are similar
 E. Teeth are structures that do not evolve by natural selection

 E. All are ways
Which of the following major discoveries does NOT show that organisms are constantly changing over time?
 A. Artificial selection
 B. Fossils
 C. Direct observation
 D. Embryology
 E. Vestigial structures
Which of the following is the most likely sequence of events?
 A. Adaptation >> Phenotype >> Mutation >> Increase in relative fitness

In a population of island hamsters, a random rockslide kills 76% of the population. Due to this event, almost all of the individuals with brown fur have been killed and now white fur dominates. What phenomenon is described here?
 A. Sexual selection
 B. Natural selection
 C. Gene flow
 D. Genetic drift
