Question

When the Grand Canyon was forming almost 10,000 years ago, a population of squirrels were separated into two separate groups. The north side of the canyon is at a higher elevation and experiences more rainfall than the south side of the canyon Over time, the two groups of squirrels have adapted to their different environments and and appear very different from one another, forming two separate species of squirrel: the Kaibab squirrels on the north and the Abert squirrels on the south.
Question 1

PART A
What type of speciation is repressed by the Grand Canyon squirrels?

Answer 1

The type of speciation represented by the Grand Canyon squirrels is **allopatric speciation**. This occurs when a population is geographically isolated, leading to the divergence of species over time due to different environmental pressures and adaptations. In this case, the Grand Canyon serves as a geographical barrier that separates the Kaibab squirrels and Abert squirrels, resulting in the formation of two distinct species.
