It is theorised that all vertebrae come from a common ancestor which then diversified; this is due to our skeletal structure. All vertebrae have the same base components to their skeleton but they adapt in certain ways as a means of fitting environmental niches.
Pentadactyl’s is the name for species with 5 fingers, and no matter what species you look at they all show these same base components. For example, even though sharks have a cartilage skeleton they still have 5 fingers running through their pectoral fins but on the complete other end of the spectrum, bats use their fingers for flight as all five fingers are extended through the wing and give structural support and allow for flight to occur.
So their you have it, bats, rats, sharks, dolphins and humans, aren’t so different when you strip us down for parts.
