Question

9 multiple choice 1 point \survival of the fittest,\ or the reproductive advantage in individuals who inherit traits that help them adapt to a changing environment was something darwin called adaptation natural selection inheritance 10 multiple choice 1 point which of the following best describes extrapolation in the context of macroevolution? describing what is observed in nature. taking what is observable in nature or the laboratory and using those data to explain something that is not observable. describing something that is observed in the fossil record describing something that is observed in the laboratory 11 multiple choice 1 point which of the following aspects of the theory of evolution as we know it today are not directly observable in the laboratory or in nature and do not harmonize with the genesis account of creation? genetic drift natural selection microevolution macroevolution 12 multiple choice 1 point which of the following is not true regarding darwins hypotheses about nature? darwin hypothesized that biogeographical phenomena, such as migration, could lead to the isolation of certain populations, potentially resulting in speciation. darwin hypothesized that molecular homology showed evidence of a single common ancestor for all living things. darwin hypothesized that small changes within populations, like those he observed in finches, could lead to larger scale changes over long time periods. darwin hypothesized that adaptation of organisms to their environment would contribute to their reproductive fitness.

Explanation:

• Question 9: Darwin defined "survival of the fittest" as natural selection. Adaptation is a result of natural selection, and inheritance is the passing - on of traits.
• Question 10: Extrapolation in macroevolution takes observable data (from nature or lab) and uses it to explain unobservable (large - scale evolutionary changes over long periods). Just describing what is observed (in nature, fossil record, or lab) is not extrapolation.
• Question 11: Macroevolution (large - scale evolutionary changes like the origin of new species, major evolutionary transitions) is not directly observable in the lab or nature in a short time frame and may conflict with a literal Genesis account. Genetic drift, natural selection, and microevolution (small - scale changes within a population) have more observable aspects.
• Question 12: Molecular homology was not hypothesized by Darwin. His work was more on observable traits, biogeography, and small - scale changes leading to larger ones over time.

Answer:

1. B. natural selection
2. B. Taking what is observable in nature or the laboratory and using those data to explain something that is not observable
3. D. Macroevolution
4. B. Darwin hypothesized that molecular homology showed evidence of a single common ancestor for all living things
