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

Question

Quizplus · Accepted Answer

Allopatric speciation occurs when a population is separated geographically from the ancestral population, leading to different genetic changes in each population over time. Eventually, the populations may become different enough that they can no longer interbreed, leading to the evolution of two different species. This is more likely than sympatric speciation, which involves the development of reproductive barriers within a single population without geographic separation. Inbreeding is not a common mechanism for speciation.
