How are two different species most likely to evolve from one ancestral species?
A) sympatrically, by a point mutation affecting morphology or behaviour
B) sympatrically, due to extensive inbreeding
C) allopatrically, due to extensive inbreeding
D) allopatrically, after the ancestral species has split into two populations

Allopatric speciation occurs when geographical barriers separate a population of organisms, leading to reproductive isolation over time. Mutations and natural selection can then result in the two populations evolving separately and eventually becoming two different species. In contrast, sympatric speciation occurs when two different species evolve within the same geographic region, which is usually a result of a genetic mutation or behavioral shift that results in reproductive isolation within a single population. While inbreeding may lead to genetic changes within a population, it is not a primary driver of speciation.
