Question

Isle Royale National Park consists of a series of islands located in Lake Superior. Initially, there were no wolves on any of the islands since they were in the middle of Lake Superior. However, in 1949 an unusually long and cold winter produced an ice bridge between Canada and the islands of the National Park. During this winter, a pair of wolves used the ice bridge to inadvertently travel to Isle Royale. "What mechanism of evolution is this

Answer 1

Geographical isolation

Step-by-step explanation:

The mechanism of evolution that is at play is geographical isolation.

The pair of wolves that used the ice bridge to travel to Isle Royale would eventually become isolated from the rest of the wolves in Canada. Due to the difference if geographical factors, each population of wolves would develop and adapt differently from each other and eventually become a separate species.

Geographical isolation is a process that occurs when a part of a population is prevented from exchanging genetic materials with the rest of the population as a result of geographical barriers with each portion of the population eventually developing to become different species.
