Solved in 2 steps
- Explain what is required for evolution by natural selection to occur in a population.Explain Natural Selection using the terms evolution, fitness, adaptation, heritable train, and mutationNatural selection is known to modify the population, stating that “the fittest individuals survive and reproduce, passing on their traits from generation to generation”. Give an example.
- Which aspect(s) of natural selection is(are) illustrated by the figure below? Check ALL answers that apply. A. Variation among individuals must be genetically transmissible to the next generation. B. Variation must exist in a population. C. Variation among individuals leads to differences in lifetime reproductive success. D. More individuals are produced each generation than the environment can support, resulting in competition for survival.List and explain the three conditions that must be met in order for a population to evolve by natural selection.Give examples of the three types of natural selection.
- Explain why natural selection is the only evolutionarymechanism that consistently leads to adaptive evolutionin a population.• Explain the difference between directional and stabilizing selection.• Give an example of how natural selection has aided in increasing genetic variety rather than decreasing it.Explain how stabilizing selection, directional selection, and disruptive selection affect the evolution of a population.
