Allopatric relationship. A geological barrier separated the two species causing it to evolve according to the environment that it lives in.
They evolved from a common ancestor.
A group of species that consists of a common ancestor and all of its descendants (also referred to as a clade).
A homeobox gene controls the development of a specific structure in an organism. These gene sequences are found in many species (from flies to humans) and can indicate a very distant common ancestor, since one ancient species might have passed on one homebox gene to two separates species.
A taxon of closely related species that share a recent common ancestor is a genus.
Evolution.
Why do scientists think related species have similar body structures and development patterns?
An ancestor.
Which squirrel, need more info.
There are two different species of grey squirrels. The "Western Gray Squirrel" and the "Eastern Gray Squirrel". Both species are mostly just called "squirrel" depending on the location one finds himself at.

They evolved from a common ancestor.
An apical ancestor is the most recent common ancestor of a group of species in a phylogenetic tree. It represents the point where the evolutionary lineage leading to a group of species splits from the rest of the tree.
a common ancestor is a species that multiple species share as the species they descended froma person born or that has lived before you and the word common means the same SO ....... its when you have the same descendant or person who lived before you or an ancestor that's the same
