Multiple Choice

How did the morphology of the Lake Apoyo cichlids help scientists understand the sympatric speciation process in this lake?

• A) Body type morphology was indicative of fish that typically live at the bottom of the lake (limnetic) and near the upper surface (benthic), separating the two species.
