The same species of squirrel lives on either side of the Grand Canyon. The squirrels on the west side of the canyon have adapted to have white fur, while the squirrels on the east side of the canyon have black fur. Which of the following has most likely led to the differences in fur adaptations? A. differences in squirrel reproductive rates
B. higher mutation rates on one side of the canyon
C. low genetic diversity in the initial population of squirrels
D. the isolation of the two groups in different environments

Answer is D

The isolation of the two groups in different environments

Explanation:

Two separate species inhabit the north and south rims of the canyon. The Kaibab squirrels inhabit the north rim and the Albert squirrels inhabit the south rim. The Kaibab squirrel became geographically isolated from the common ancestor with its closest relative, the Albert squirrel in the North Rim of the Grand Canyon about 10,000 years ago.

the anti federalists was a movement that was opposed to the creation of a us federal government. although they were not as organized as the federalists, they also had a large group of leaders, especially in state politics.

the statement "now, in a large extended country, it is impossible to have a representation, possessing the sentiments, and of integrity, to declare the minds of the people” represents the concerns of the anti federalists.

they strongly believed that the federalists were representing the interests of aristocratic elements of society at the expense of the majority of ordinary people, who lived in a rural society.

their fear for the creation of a strong federal government and the president’s power of veto in their opinion would create a tyrannical rule that would dominate the people. they defended the importance of restraining the government’s power towards people at any cost.
