common ancestor species, populations of which were separated as the canyon formed. if this hypothesis is correct, it would be an example of Allopatric speciation by Vicariance

The process through which new species develop from an existing species is known as speciation.

Allopatric speciation, sympatric speciation, and parapatric speciation are three broad categories of speciation.

When groups of individuals from a given population are divided by a physical barrier, such as a mountain, river, etc., allopatric speciation occurs.

When a group of individuals from the same species fill distinct niches in the same habitat, parapatric speciation occurs, leading to the emergence of novel characteristics.

When members of a population fail to identify one another as possible partners, sympatric speciation results.

The Grand Canyon, a physical barrier, kept the antelope ground squirrels apart in the situation at hand.

Once more, the Grand Canyon, not population migration to a divergent location, caused the population to split.
