Question 2 2. The evolution of the brain and mind is testable because:

Question 3 3. A scientist has observed animals in a particular habitat for some time. She notices that in a population of birds those with either short or long beaks can find more food than those with average sized beaks. Over time, she notices a higher proportion of birds in the population have either short or long beaks. She is observing:

Question 6 6. Compared to native South Americans, native North Americans would be expected to have _______.

Question 7 7. Why are alleles the driving force behind a population's evolutionary path?

Question 8 8. After observing a population of fish with interesting protective spines, a scientist decides to move two of the fish into a new pond to create a new population of fish to study the ability of the fish to survive a new set of predators. Which of the following evolutionary agents did the scientist introduce?

Question 9 9. Using the criteria outlined in the Hardy-Weinberg equilibrium, determine which of the following populations can be balanced.

Question 11 11. How do losses of alleles in natural selection differ from losses of alleles in genetic drift?

Question 12 12. What is eugenics?

Question 13 13. Intraspecific competition usually gives rise to which of the following dispersion patterns?

Question 14 14. Cheetahs can accept skin grafts from other cheetahs. This shows us that:

Question 15 15. Consider a population of fish where the length of a given fish's dorsal spine is determined by a single gene, which is defined by two different alleles. The dominant A allele encodes a long dorsal spine and the recessive an allele encodes a short dorsal spine. The fish is diploid and reproduces sexually. If the number of AA individuals is 500, the number of Aa individuals is 200, and the number of aa individuals is 300, then what is the frequency of 'A' in this population?
