Summary Introduction
To explain: The reason that how the animals assist individuals that could evolve through kin selection.
Concept introduction: Altruism is a process when an organism behaves in a way that benefits others instead of being harmed or risking oneself. Eusocial animals are organisms that live in a multigenerational family group with a reproductive division of labor. The only way to develop the altruistic behavior is through kin selection.

Differentiate Kin selection from altruism.
You document altruism in an animal species that you are studying: female zebras running at the back of the group, closest to the pursuing predator, as the group runs to escape a predator. Both kin selection and reciprocal altruism can explain this behavior. What piece of evidence would support the hypothesis that it's kin selection?
Cooperative behaviour is widely found among animals. Provide the following:
1) an example of cooperative behaviour between genetically related individuals
2) an example of cooperative behaviour between unrelated individuals. For each of the examples, also describe the mechanism(s) involved in maintaining cooperative behaviours during their interactions.

One of these strategies is the ability to learn. As we discussed, not every animal can learn and there are clear costs and benefits to this strategy. Suggest one benefit of the ability to learn and one potential cost. Briefly explain each. (1-2 sentences for each) Since learning is not universal, under which circumstances would it be most likely be a successful strategy? We discussed a framework that examines the influence of predictability on the success of learning ability. Describe this framework. Make sure you discuss all the available conditions and clearly state under which we would expect learning to be successful and where we would not expect it to be successful.
