A pоpulаtiоn оf 5,000 frogs lives on а lаrge island. After a volcanic eruption, only 50 frogs survive, and the new population has much lower genetic diversity than before. Several generations later, 20 frogs from the surviving population are carried by a storm to a nearby island. These colonists establish a new population whose allele frequencies differ substantially from the source population. Which statement correctly identifies the evolutionary process responsible for each event?
