Theories of Evolution

Microevolution, as distinct from macroevolution, specifically refers to

• A.small-scale genetic change occurring within a single population
• B.large-scale change resulting in the formation of an entirely new species
• C.the complete absence of any evolutionary change of any kind whatsoever
• D.a factor entirely unrelated to small-scale change within a single population

Evolution, according to modern theory, specifically is understood to have

• A.a factor entirely unrelated to having no predetermined direction or goal
• B.already been fully completed, with no further evolutionary change possible
• C.a single, fixed, predetermined goal toward which every species is working
• D.no predetermined direction or ultimate goal

Evolution, according to modern theory, specifically is understood to occur mainly at the level of

• A.a single individual organism exclusively, during the course of its own lifetime
• B.a factor entirely unrelated to occurring at the level of populations
• C.populations, rather than within a single individual during its own lifetime
• D.a single cell exclusively, considered entirely apart from any wider population
