3. Blue jays seem better than robins at recognizing individuals. In one study, blue jays raised by robins (a method known as cross-fostering, blue jay eggs are placed in robin nests) could distinguish strange fromfamilar robins better than the robins could. What mechanism for the evolution of altruism, if any, is likely to operate in blue jays (1)? State two conditions that are required for the mechanism that you propose (2)? Pickone of those conditions and briefly describe how you could determine whether or not it occurs in blue jays (2)?

Explanation / Answer

Ans. In blue jays there is reciprocal atruism which one organism increases the fitness on the sake of its own fitness with an expectation that the other organism will also help him in the response.Iin this case there “reciprocal altruists” stop cooperation in the first instance of non-cooperation by an opponent and stay non-cooperative from thereon.

This is why blue jay supports Robin in their fitness more to fit in nature for survival so, blue jay recognize Robin much better than Robin themselves. This is why Blue

Condition required for the Reciprocal altruism are:

Ques.Pickone of those conditions and briefly describe how you could determine whether or not it occurs in blue jays

Ans. The condition that ability to distinguish between strange (non-
relatives) and familiar (relatives) individuals shows that Kin selection is more prominent in Blue jays as compared to the Robins which are not able to distinguish strangers and familiar individuals.
