Short antennae is considered a convergent trait across the several beetle lineages that evolved aquatic lifestyles independently. Researchers propose that short antennae reduce drag during swimming, which explains why this adaptive trait has evolved multiple times, associated with transitions to aquatic lifestyles. However, simply comparing average antennal lengths (relative to body size) across species is not enough to test the hypothesis that this trait is an adaptation to aquatic lifestyles since aquatic beetle species are not independent observations. A) Explain why aquatic beetle species are not independent observations. (2 pts) B) Propose an approach to test the hypothesis that having short antennae is an adaptation to aquatic lifestyles across beetle species.
