Come up with five different alternative hypotheses to explain why a species of fish might show schooling behaviour. Use the form, "Natural selection might select for schooling behavior in fish since fish that exhibit schooling behavior would leave more offspring than fish that don't exhibit schooling behavior because...

Expert Solution

Schooling behavior: Collective animal behavior in which a group of organisms stay together and move in the same direction.

Ex: Fish

Advantages of schooling behavior in fishes: (Hypotheses to explain why a species of fish might show schooling behavior)

i. To swim more efficiently against the stream: The streamlined movement of the fish group provides additional thrust force for movement.

ii. Better protection against predators: The group may threaten the predator by forming a large association.

iii. The higher success of finding a mate: It is always i=easier to find a mate in a group than in isolation.

iv. Reducing the chances of individual capture: The individual capture rate is low in a group

v. Enhanced foraging success: If a group member finds a=food, it can lead other members to that site.

vi. Better care of young progeny: The progeny can be provided better nutritional care and protection in a group.

All these features help a fish to survive and reproduce successfully.

In African cichlid fish, there are > 2000 different species that vary in their craniofacial structure based on whether they are pelagic (live in open water, feeding on smaller fish) or benthic (living at the bottom of the lake, feeding mostly on invertebrates such as snails). They are all derived from a common ancestor that may have left the Nile River and invaded at least three lakes including Lake Victoria, Lake Malawi, and Lake Tanganyika. Describe how cichlids represent a...
