Chapter 53.12, Problem 2LO
Summary Introduction
To determine: Kin’s selection and inclusive fitness.
Introduction: Kin selection is the term associated with altruistic behavior. Altruism is a behavior shown by one organism that benefits the other individual at some cost paid by the organism showing this behavior. Kin selection and inclusive fitness were defined by Hamilton.

Differentiate Kin selection from altruism.
Using the concept of inclusive fitness (and kin selection), explain how altruistic behavior (e.g. where an
individual protects for another, even at their own expense) can evolve by natural selection? Make sure to
explain what inclusive fitness is. (remember the concentric circles on the slide)
How in practice does kin selection work?
