Answer:

thank me

Step-by-step explanation:

As the canyon deepened, it acted as geographic barrier to squirrel populations on either side. Two squirrel species evolved as a result of allopatric speciation. Eventually, the canyon became too deep for the squirrels to cross and a subgroup of squirrels became isolated on each side.
