Biology: Concepts and Connections, 6e (Campbell) Chapter 14    The Origin of Species Multiple - Choice Questions 1) What is the significance of color in the diversification of cichlids in Lake Victoria?  A) Female choice for specific male color patterns could reproductively isolate subpopulations of cichlids.  B) Bright color patterns scare potential predators, allowing more species to thrive in the lake.  C) Bright color patterns allow biologists to recognize differences among species they would otherwise fail to notice.  D) Bright color patterns in female cichlids are an exception to the rule that males are usually showier.  E) Bright colors appear only in species that live in murky, polluted water.  Answer:  A  Topic:  Opening Essay  Skill:  Conceptual Understanding 2) Speciation, or the formation of new species, is  A) a form of microevolution.  B) completed when the new species is able to interbreed with at least one additional species.  C) the bridge between microevolution and macroevolution.  D) a process that requires at least 1 million years, as seen in the Lake Victoria cichlids.  E) an event that has occurred only a few times in the history of the planet.  Answer:  C  Topic:  Opening Essay  Skill:  Factual Recall 3) Which of the following would a biologist describe as microevolution?  Topic:  14.1  Skill:  Conceptual Understanding 4) A biological species is defined as a group of organisms that  1

Topic:  14.2  Skill:  Factual Recall  5) The biological species concept is  A) applicable to all forms of life, past and present.  B) applicable to all present life forms, but not to fossil organisms whose reproductive behavior cannot be observed.  C) easy to apply to all present sexually reproducing organisms, but harder to apply to asexual organisms and fossils.  D) difficult to put into practice even for present sexual organisms, and useless for asexual organisms and fossils.  E) based on DNA, so it applies to all forms of life from which a DNA sample can be collected.  Answer:  D  Topic:  14.2  Skill:  Conceptual Understanding

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
