The Inclusive Fitness Revolution inclusive fitness: taking in consideration genes siblings may pass on (count up all genes from family members and add up for reproductive success) Inclusive Fitness genes eye view of NS is important: we look at the genes trying to reproduce and self- promote (do a lot of things harmful things to organisms as long as they are reproducing) hamiltons point of view : actor= individual doing the thing, recipient= individual thing is being done to. the gene in one body is also in the recipient’s body b: benefit gained by the recipient if the equation is satisfied, then behavior has a high probability of evolving why reduce the cost by relatedness level? We are not related 100% to the individuals inclusive fitness : all of reproductive success from direct and indirect descent (relatives, family members) Adaptation and Natural Selection George Williams: thought of what is an adaptation something that is adapted helps increase reproductive success not everything is an adaptation, in order for something to be an adaptation it must be: o reliable : is everyone doing it? o Efficiency : o Economy : does it prevent wasting resources when it doesn’t have to? Robert Trivers He explained reciprocal altruism (a different view of inclusive fitness) Parental investment theory : Parent-offspring conflict : you may share 50% genes w/brother, so you have 25% genes

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
