• geographical isolation
• temporal isolation
• anatomical isolation

T13. Gentoo penguins will present a mate with a pebble that they find to attract a mate. Emperor penguins have a specific call and movement that they make to attract a mate. Which type of isolation do these penguins demonstrate?

• temporal isolation 
• behavioral isolation
• geographical isolation
• anatomical isolation

T13. On island chains like the one shown below, animal populations that spread from the main island to the other islands can evolve into separate species. Which of the following best explains why speciation is favored in such a situation? 

• Predators on the main island can easily migrate to follow the populations to the other islands.
• The physical separation of the islands from the main island limits gene flow and interbreeding between the populations.
• Lack of disease on the other island enables the populations to grow and change without limits.
• The climatic conditions of the islands allow the populations to breed all year long and produce several generations.

T13. What is speciation?

• combining of tow species to form one with different traits
• isolation that affects mating behaviors
• timing of mating that prevents normal sexual selection
• divergence of two or more species from an existing one

T14. Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population
