Which one of the following statements about natural selection is not correct?

Result
Your answer: —  ·  Correct: A

Explanation

Natural selection is the process by which individuals with characteristics best suited to their environment are more likely to survive and reproduce. For natural selection to occur, variation must exist within a population. If all members of a species were identical, there would be no traits to "select" over others; thus, statement A is incorrect.

  • Statement B: This is the core outcome of natural selection, leading to adaptation over generations.
  • Statement C: Darwin observed that populations produce more offspring than resources can support, leading to a "struggle for existence."
  • Statement D: Genetic variation is driven by mutation (source of new alleles), meiosis (crossing over and independent assortment), and sexual reproduction (random fertilization), providing the raw material for evolution.
