Question

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 from familar 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)? Pick one of those conditions and briefly describe how you could determine whether or not it occurs in blue jays (2)?

Explanation / Answer

What mechanism for the evolution of altruism, if any, is likely to operate in blue jays ?

Birds like blue jays show complex social structure. The younger ones of Blue jays show observational leaning when they are captive raised by other birds.

Its a natural selection phenomenon obsersed in blue jays to protect themselves from predators when they are grown.

Here the genes play important role in chossing the organism to be benefited , selfish and the other organism to show altruism at its own cost.

State two conditions that are required for the mechanism that you propose ?

adaptation and group selection.

Pick one of those conditions and briefly describe how you could determine whether or not it occurs in blue jays ?
