Members of two different species possess a similar-looking structure that they use in a similar way to perform about the same function. Which of the following would suggest that the relationship more likely represents homology instead of convergent evolution?
A) The two species live at great distance from each other.
B) The two species share many proteins.
C) The structures in adult members of both species are similar in size.
D) Both species are well adapted to their particular environments.

Sharing many proteins suggests that the two species may have a common ancestor and inherited the similar structure from a shared ancestor (homology) rather than evolving the structure independently due to similar environmental pressures (convergent evolution).
