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 observations would suggest that the relationship more likely represents homology than convergent evolution?
A) The two species live at great distance from each other.
B) The embryological development of the two structures are similar.
C) The structures in adult members of both species are similar in size.
D) Both species are well adapted to their particular environments.

Homology refers to similarities between species that arise from a common ancestor. Similar embryological development of structures in different species suggests a common evolutionary origin, indicating homology rather than convergent evolution, where similar structures evolve independently in unrelated species due to similar environmental pressures.
