Before Darwin, scientists such as Lamarck envisioned evolutionary change as transformational—properties of an ensemble change because every member of the ensemble changes

Darwin's theory of evolutionary change was by contrast a variational one—the properties of an ensemble change because of the action of some sorting process acting on preexisting variation within the ensemble. Re-ferring to the figure above, describe the kind of sorting process that takes place when we use artificial selec-tion to change the characteristics of a breed of animals or plants and when natural selection operates on a population.

What will be an ideal response?


ANS:
Answers will vary, but should include: For artificial selection, the sorting process is determined by the breeder making choices about which individuals will breed. For natural selection, the sorting process is de-termined by which variants survive and most successfully reproduce.
