Besides cooperation with an immediate benefit for both actors, this behavior appears to occur mostly between relatives.[1] Spending time and resources assisting a related individual may at first seem destructive to the organism's chances of survival but is actually beneficial over the long-term. Studies conducted on red wolves support previous researchers'[8] contention that helpers obtain both immediate and long-term gains from cooperative breeding.
