|
Coefficient of relatedness |
Fraction of alleles that 2 individuals share due to having a shared ancestor |
|
Kin selection |
Selection in which a trait becomes more or less common because it affects reproductive success of relatives more than non relatives |
|
Reciprocal altruism |
Altruistic behavior that is selected altruist is consistently repaid more than cost of action |
|
Sexual selection |
Selection that favors physical or behavioral traits that increase male success in mating |
|
Intrasexual selection |
Selection due to differences of same sex mating differences male male competition compete for access to females |
|
Intersexual selection |
Female choice females mate with given trait so it becomes exaggerated in males peacocks |
|
Altruistic behavior |
Behavior has cost to actor and benefit to another |
|
Inclusive fitness |
Total number of copies of individuals alleles to next generation both directly and indirectly |
|
How can natural selection lead to altruistic behavior using concepts of kin selection inclusive fitness and Hamilton's rule? |
Altruistic behavior can be favored of recipient is a relative of the actor and the cost to actor is less than benefit to recipient discounted by fraction of alleles that they share by descent |

|
Neocortex |
Executive in charge of making decisions neocortex ratio fraction of the brain that is neocortex |
|
Social intelligence hypothesis |
Greater intelligence was favored because it allowed brains to keep track of social dynamics of bigger groups |
|
Flexible behavior hypothesis |
Greater intelligence helped individuals solve new problems by inventing the new behaviors themselves and by being able to learn from others |
|
