Detailed Solution for Test: Biological Explanations of Social Behavior in Animals - Question 7
  • An organism may find that it would be beneficial to incur the cost of lowering their own fitness to help another if there is a chance of being in a situation where the one helped will return the favor.
  • This is a type of cooperation that is at first unconditional, but with expectations that this cooperation would be later maintained.
  • Reciprocal altruism is when an organism behaves in a way that reduces its fitness while increasing another organism's fitness, with the expectation that the other organism will act in a similar way later on.

Altruism among organisms that are genetically similar allow these genes to be passed on to the next generation. Altruistically, organism behavior supports the survival of a relative or other individual organism, and enhances the genetic fitness of both the recipient of the act and the altruistic organism. This is an example of:
Detailed Solution for Test: Biological Explanations of Social Behavior in Animals - Question 8
  • This theory is a model for the evolution of social behaviors or social traits.

Detailed Solution for Test: Biological Explanations of Social Behavior in Animals - Question 10
  • Foraging behaviors is optimal when net energy gained in feeding is maximized
  • The energy content of the food (benefit) minus the energy spent in pursuing the food (cost) is taken into consideration.
  • Natural selection also favors behaviors that maximize energy acquisition if increased energy leads to increases in reproductive success.
  • Therefore, bigger birds eat more because maximum energy acquisition may lead to increases in reproductive success.
