In a hypothetical environment, fishes called pike-cichlids are visual predators of algae-eating fish (i.e., they locate their prey by sight). If a population of algae-eaters experiences predation pressure from pike-cichlids, which of the following should least likely be observed in the algae-eater population over the course of many generations?
I know the answer is "Selection for larger female algae-eaters, bearing broods composed of more, and larger, young" but can you provide an explanation of why this is the correct answer?
