Respuesta :

B. A population must be isolated in some way.

Explanation:

  • Speciation refers to the origin of new species from a pre-existing species.
  • Speciation can be Gradual or instantaneous depending on the time taken for evolution of new species.
  • Speciation occurs when gene pool of a population is somehow reproducively isolated from other populations of parent species.
