Question

which is an example of kin selection?
a wolves hunting in a pack
b a squirrel chattering to distract a predator from its close relatives
c fish swimming in schools
d all of the above

Explanation:

Kin selection is the evolutionary strategy where an organism acts to increase the fitness of its relatives (who share its genes) at a cost to its own fitness. Option a: Wolves hunting in a pack may involve cooperation but not necessarily kin - directed altruism (packs can have non - kin). Option c: Fish swimming in schools is for protection/efficiency, not kin - specific. Option b: A squirrel distracting a predator from its close relatives is altruistic behavior towards kin, increasing relatives' survival (and thus shared genes' propagation) at its own risk, fitting kin selection.

Answer:

b. A squirrel chattering to distract a predator from its close relatives
