Imagine a scenario where a lake dries up enough to become two separate lakes, dividing a population of fish into two daughter populations. This is an example of
A) allopatric speciation.
B) sympatric speciation.
C) both allopatric and sympatric speciation.
D) neither allopatric or sympatric speciation.

Allopatric speciation occurs when a physical barrier separates a population, like a mountain range, a river, or in this case, a dried-up lake. The two daughter populations will evolve separately because they are no longer able to interbreed. In this case, the separation is caused by a geographical barrier, making it allopatric speciation. Sympatric speciation occurs when species diverge within the same geographical space, without any physical barrier, which is not the case here.
