Monkeys and bats have similar bone structure in their forelimbs. however, monkeys have longer forelimbs to use for climbing and swinging in trees. bats have shorter forelimbs to use for flight. which term best describes how monkey and bat forelimbs are related to each other? a. homologous b. embryonic c. analogous d. vestigial

Hi!

The correct option would be A.

Homologous structures are those structures which have a common structure and consequently origin (the bone structure is the same in both monkeys and bats in our case). These structures, however, perform different functions in different species (used for climbing in monkeys, and flight in bats).

They are called homologous structures because the underlying anatomy of these are same in different species, and indicative of a common ancestor. The difference in the appearance is due to the adaptation of these structures to accommodate different lifestyles of the species.

Hope this helps!
