To learn more about this topic, start your googling with these keywords:
Life history strategy: How organisms allocate energy usage to maximize offspring.
Parental Investment: Any non-genetic contributions by parents to help their offspring survive.
Brood Parasites: Organisms that rely on others to raise their young.
Mafia Behavior: The practice of repeatedly visiting victims to make sure they are complying.
Fecundity: The number of offspring produced by an individual over time.
