Question 11 of 31 3.0 Points A classic scientific study showed that crayfish on one side of the isthmus of Panama were more closely related to other species on the other side of the isthmus than to each other. The most likely explanation for this result is: • A. gene flow • B. dispersal • C. mutation • D. vicariance Feedback:The most likely explanation is that a several separation crayfish species were separated by the formation of the isthmus and the then separated populations diverged.

Question 12 of 31 3.0 Points What is microevolution? • A. the field of study which examine allele frequencies. • B. the change that gives rise to new species. • C. the change in allele frequency in a population. • D. due to detrimental effects on fitness.

A new purple allele arises in the population by mutation. • C. In a population flowers that carry purple alleles are pollinated more often. • D.

Question 15 of 31 3.0 Points How did Darwin define evolution? • A. adaptation to climate • B. inheritance of acquired characteristics • C. descent with modification • D. change in allele frequency over time Feedback:Darwin described an evolutionary process that occurs when change happens in populations over generations. Read more in Chapter 11. Question 16 of 31 3.0 Points Which of the following is correct? • A. One important fact of evolution is that organisms evolve on purpose. • B. Since evolution occurred in the past it cannot be studied scientifically. • C. Evolution is a just a theory that has little evidence to support it • D. Evolution is widely accepted based on scientific data and evidence. Feedback:Great job. Question 17 of 31 3.0 Points What is the change in a population’s allele frequency from one generation to the next that is due to chance known as? • A. natural selection • B. migration • C. mutation • D. genetic drift Feedback:Unlike natural selection that leads to adaptation, genetic drift is a process that is based on random statistical sampling. Read more in Chapter 11. Question 18 of 31 3.0 Points A population of pocket mice has two coat colors: black and brown. There are more black mice on lava rocks where there are hawk predators. This is an example of: • A. Mutation • B. Genetic drift • C. Macroevolution • D. Natural selection Feedback:Mice that are the same color as the rock (black) are able to survive predator attacks better because they are more camouflaged. This is an example of natural selection.
