To propose a hypothesis: To explain the advantages a helper scrub jay might gain from its role in the co-reproductive behavior.
Introduction: Non-cooperative breeding occurs when an individual other than the parent of the same species are deployed in providing the care to the offspring of the breeding mates. This is an example of altruism which describesa behavior that reduces an organism's own fitness but enhances the fitness of others in the population.
In case of scrub jays it is found that helper birds often assist mated pairs of birds by gathering food for their offspring.
To review: The validity of the hypothesis.
