Questions and Answers

What is the primary function of natural selection in organisms?

  • To eliminate all non-adaptive traits
  • To ensure all organisms are genetically identical
  • To enable organisms to evolve and adapt to their environment (correct)
  • To create entirely new species

    • Which of the following statements about natural selection is false?

  • Natural selection involves the survival of organisms with advantageous traits
  • Natural selection can result in the adaptation of organisms to their surroundings
  • Natural selection only occurs in response to environmental changes (correct)
  • Natural selection can lead to the evolution of species over time

    • How does natural selection influence an organism's traits?

  • It preserves advantageous traits and discards neutral or harmful ones (correct)
  • It ensures that all traits are passed on equally
  • It eliminates all variations in traits over generations
  • It randomly alters traits regardless of their benefits

    Study Notes

    Natural Selection Overview

    • Natural selection acts as a mechanism for evolution, favoring traits that enhance survival and reproductive success.
    • Organisms with beneficial traits are more likely to reproduce and pass those traits to the next generation.

    False Statement About Natural Selection

    • A common misconception is that natural selection always leads to perfection; however, it only leads to adaptations that suit current environmental conditions.

    Impact of Natural Selection on Traits

    • Natural selection shapes an organism's traits by promoting genetic variations that provide advantages in a specific environment.
    • Traits that increase survival rates, such as camouflage or resistance to disease, are more likely to be inherited.

    Consequences Over Generations

    • Over many generations, natural selection can lead to significant shifts in the traits of a population, potentially resulting in speciation.
    • Constant environmental changes can push a population to adapt or face extinction.

    Outcomes of Natural Selection

    • The primary outcome of natural selection is increased prevalence of advantageous traits within a population.
    • It can also lead to decreased genetic diversity if only a few traits dominate due to selection pressures.
