Scientific theory holds that convergent evolution occurs when different
species independently evolve analogous structures, or features that may appear
different, but perform the same function. Creatures evolve such structures in
order to adapt to their environments.
A scientist argues that bats and birds have analogous structures. Which of the
following supports his argument?
A. Bats use echolocation to track their prey, while birds rely primarily on
sight.
B. Unlike bird wings, bat wings are composed primarily of membrane, but both
types of wings provide flight capabilities.
C. Baby bats gain nourishment from their mother's milk, while baby birds eat
worms and bugs brought by their mothers.
D. Both bats and birds frequently make their homes in trees, bridges, and
attics.
