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?

#Section 2: Evolution

Selection for drab coloration of the algae-eaters
Selection for nocturnal algae-eaters (active only at night)
Selection for larger female algae-eaters, bearing broods composed of more, and larger, young
Selection for algae-eaters that become sexually mature at smaller overall body sizes
