When a single species evolves into two species,the new species must
A)be reproductively isolated.
B)evolve different diets.
C)be exposed to the same selective pressures.
D)live on a different continent.

Question

Quizplus · Accepted Answer

Reproductive isolation is a necessary factor for the evolution of new species as it prevents interbreeding between the two populations, leading to the accumulation of genetic differences over time. Therefore, option A is the correct choice. Option B may or may not happen, and option C is not necessary as it is possible for the two new species to live in the same environment and still evolve separately. Option D is also not necessary as speciation can occur within the same geographic region.
