1. Theory is narrower in scope than hypothesis: FALSE. Broader in scope than
a hypothesis. General and can lead to new testable hypothesis.
2. The domain Eukarya includes all prokaryotes: FALSE.
3. Natural selection results in the adaptation of organisms to their environ-
ment: TRUE.
4. An observation is a tentative answer to a well-framed question: FALSE.
Hypothesis
5. Hypothesis can be proven: FALSE. Must be testable and falsifiable.
6. Microevolution consists of changes in allele frequency in a population over
time: TRUE.
7. Macroevolution refers to broad patterns of evolutionary change above the
species leve: TRUE.
8. Hybrids are the offspring of crosses between different species: TRUE.
9. Polyploidy is very common in animals: FALSE. More common in plants
10. Paleontology is the study on the formation of Earth: FALSE. the study of
fossils
11. Artificial selection involves selective breeding: TRUE.
12. Populations, not individuals, evolve over time: TRUE.
13. A phylogenetic tree represents a hypothesis about evolutionary relation-
ships: TRUE
14. Homology is similarity due to shared ancestry: TRUE.
15. Cladistics groups organisms by common descent: TRUE.
16. Convergent evolution occurs when unrelated groups adapt to similar en-
vironmental pressures: TRUE.
17. A molecular clock is always very accurate: FALSE.
18. Maximum parsimony assumes that the most likely phylogenetic tree is the
most complex one: FALSE. Maximum parsimony assumes that the most likely tree
is the one that requires the fewest evolutionary events
19. A phylogenetic tree represents hypotheses about how organisms are
related to each: TRUE.
20. Variation in heritable traits is a prerequisite for evolution by natural selec-
tion: TRUE
21. Phenotypic variation always results from genetic differences: FALSE, NOT
ALWAYS BUT MOST COMMON. Other factors include mutation, gene duplication,
enviroment etc.
22. Natural selection can only act on phenotypic variation that has a genetic
component: TRUE.
23. Sexual reproduction creates genetic variation by arranging existing genes
in new ways: TRUE.

24. The Hardy-Weinberg Equation can be used to test whether a population is
evolving: TRUE.
25. The Hardy-Weinberg equation: describes the genetic makeup expected for a
population that is not evolving at a specific locus
26. Which of the following types of cells utilize deoxyribonucleic acid (DNA)
as their genetic material but do not have their DNA encased within a nuclear
envelope?: Archaea
27. The biological species concept is inadequate for grouping: Asexual organ-
isms
28. The scientific study of the geographic distribution of species: Biogeogra-
phy
29. Polyploidy: A condition in which a species originates from an accident during
cell division that results in extra sets of chromosomes
30. A rapid method of speciation that has been important in the history of
flowering plants is.: Polyploidy
31. Natural selection is a process in which.: individuals with favorable inherited
traits are more likely to survive and reproduce
32. taxon, all of whose members have the same common ancestor, is: mono-
phyletic
33. The discipline that classifies organisms and determines their evolutionary-
: Systematics
34. the taxonomic groups from least to most inclusive are: Species, genus,
family, order, class, phylum, kingdom, domain
35. Sister taxa on a phylogenetic tree.: are groups that share an immediate
commonancestor not shared by any other group
36. A basal taxon on a phylogenetic tree: A lineage that diverges from all mem-
bers of its groupearly in the group's history
37. The three-domain system includes: Bacteria, Archaea, and Eukarya
38. Prezygotic isolating mechanisms ensure that: Hybrids are never conceived
or born
39. Speciation occurs when: Enough differences accumulate between two popu-
lations that they can no longer interbreed
40. Members of different species do not normally produce offspring due to: 1.
Differing courtship rituals (Behavioral isolation)
2. Varying breeding times (Temporal isolation)
3. Gamete incompatibility (Gametic isolation)
4. Morphological differences (Mechanical isolation)
5. They occupy different habitats (Habitat isolation)
