As you hike from the highest elevation to the lowest elevation, you find three different species of related mice. None of them are found at the same elevation, and the vegetation changes at each elevation level. Using species C as a reference, you find that there are more genetic differences between species A and species C than between species A and species B. Which of the following statements would best reflect the mode of speciation in these mice?-Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original population.-Only genetic drift is responsible for the differences observed.-Species C arose from species A later than species B. speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.

Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.

Explanation:

The new species can be formed in one of the three ways that are allopatric, peripatric, and parapatric speciation.

The allopatric speciation gives rise to new species due to the geographical barriers present between them and the peripatric speciation occurs when a small population enters into a new habitat.

In the given question, species A is more closely related to species B as to species C. This could be due to the allopatric speciation or peripatric speciation but it would depend on the number of the individuals of the population that dispersed to a different elevation which provided a new niche.

Thus, the selected option is correct.
