1. What does natural selection least depend on?
Advertisement
a. Adaptation to the environment b. Reproductive success c. The size of the population d. Competition for resources
Answer: c. Natural selection depends on each of these things but it is least affected by the size of the population undergoing natural selection.
2. The physical characteristics of an organism is called what?
a. Phenotype b. Genotype c. Genome d. Mutational trait
Answer: a. The phenotype involves the characteristics of a specific organism. It is based on its genome or genotype and can change because of mutations in the genome from the time of birth.
3. What term best describes the phenomenon of selective breeding in domesticated animals?
a. Sexual selection b. Artificial selection c. Trait analysis d. Formation of an ecological niche
Answer: b. Selective breeding is a type of artificial selection that is done with the purposes of choosing traits that are desirable and breeding those animals with the desirable traits.
4. What do researchers in evolutionary developmental biology or evo-devo actually study?
a. Changes in phenotype among populations of organisms b. Genetic variations between organisms of the same species. c. Protein differences between different species. d. The developmental changes that occur in embryos.
Answer: d. Researchers in evolutionary developmental biology or evodevo study the relationships in the organisms by looking at the developmental changes within embryos themselves.
5. What type of selection is happening with the differences in plumage among male peacocks?
a. Ecological selection b. Kin selection c. Sexual selection d. Gametic selection
Answer: c. Sexual selection is the choosing of a sexual mate over others of the same gender. This is what happens when female peacocks choose a sexual mate on the basis of the male s plumage.
6. Competition among members of the same gender for mates of the opposite gender is referred to as what?
a. Intrasexual competition b. Intersexual competition c. Gametic selection d. Fecundity selection
Answer: a. Intrasexual competition is that which occurs among members of the same gender in order to be more attractive to the opposite gender.
7. Which type of adaptation is not helpful for an organism’s survival?
a. Deleterious adaptation b. Structural adaptation c. Physiological adaptation d. Behavioral adaptation
Answer: a. Each of these adaptations can be helpful for the survival of an organism but a deleterious adaptation will not be helpful and will reduce the chances of survival.
8. What is not a physiological adaptation in an organism?
a. The making of venom b. The capacity to learn c. The ability to regulate temperature d. The making of slime
Answer: b. Each of these is a physiological adaptation except for the capacity to learn, which is a behavioral adaptation.
9. The phenomenon of a trait that was once adaptive but is no longer adaptive or may be maladaptive is called what?
Answer: d. Vestigial adaptations, like the appendix and wisdom teeth, were likely once functional but are no longer serving any helpful function.
10. The phenomenon of a trait that does not appear to have any specific function in an organism is called what?
Answer: b. A spandrel is a trait that does not appear to have any adaptive function in an organism.
