BIO 322 Final Exam 2026/2027 | 300+ Questions & Answers | Evolution, Natural Selection, Phylogeny, Population Genetics, Coevolution & Human Evolution

This BIO 322 Final Exam 2026/2027 study resource provides 300+ exam-style questions and answers across 158 pages, offering extensive preparation for a comprehensive evolutionary biology final. The material covers the history and foundations of evolutionary theory, including Darwin, descent with modification, natural selection, the modern evolutionary synthesis, microevolution and macroevolution. It also examines scientific hypotheses, common ancestry, evolutionary evidence and the relationship between mutation, heritable variation and natural selection. A substantial section focuses on phylogenetics, systematics and molecular evolution. Questions address Linnaean classification, species nomenclature, monophyletic groups and clades, homologous characters, synapomorphies, homoplasy, convergent and parallel evolution, gene trees, species trees, horizontal gene transfer, paralogous genes and molecular clocks. Students also encounter evolutionary radiation, mosaic evolution, vestigial characters, Dollo's law, phylogenetic niche conservatism, punctuated equilibrium, gradualism, saltation and evolutionary trends. The final-exam material extensively reviews natural selection and population genetics, including evolutionary fitness, selection coefficients, fixation of beneficial alleles, selective sweeps, linkage disequilibrium, genetic variation and balancing selection. Mutation-related questions cover germ-line mutations, random mutation, epigenetic inheritance, homeotic mutations, synonymous and nonsynonymous changes, chromosome fusion and the relationship between mutation and adaptation. The resource also explores adaptations, exaptations, evolutionary trade-offs, phylogenetic constraints and the use of comparative approaches to test adaptive hypotheses. Students can also review macroevolution, diversification, extinction and the fossil record, including evolutionary radiations, speciation and extinction rates, diversity equilibrium, mass extinctions, the Red Queen hypothesis, key adaptations, competitive displacement and incumbent replacement. Questions extend into the Permian extinction, Mesozoic and Cenozoic diversification, mammalian radiation and the evolutionary consequences of ecological opportunities following mass-extinction events. The document further covers coevolution, behavioral evolution and social evolution, with questions on predator-prey and host-parasite interactions, escape-and-radiate coevolution, brood parasitism, Müllerian mimicry, aposematism, mutualism, ecological character displacement, altruism, kin selection, inclusive fitness, evolutionarily stable strategies, haplodiploidy and multilevel or group selection. Life-history evolution is addressed through fecundity, survival-reproduction trade-offs, intrinsic population growth, senescence, antagonistic pleiotropy, parental investment, iteroparity, niche specialization and ecological strategies. Another important component examines sexual selection and reproductive evolution, including anisogamy, hermaphroditism, reproductive assurance, good-genes mechanisms, sperm competition, Bateman's principle, female choice, sexual dimorphism, inbreeding, clonal interference, the costs and advantages of sexual reproduction and the Red Queen explanation for sex. The later material also reaches primate and human evolution, including bipedalism, anatomical adaptations of modern humans, Australopithecus, the genus Homo, human migration and evidence concerning the African origin of modern humans. Relevant students: BIO 322 students, evolutionary biology students, population genetics students, ecology and evolution students, genetics students, zoology students, biological sciences majors, molecular evolution students, anthropology and human evolution students, and undergraduate life science students preparing for comprehensive evolutionary biology final examinations.
