relative number of an ind. alleles that are passed on to further generations from one’s own offspring and that of related ind.
fitness
measures an animals offspring and increase or decrease in genes shared in the same gene pool
organism acts in a manner that temporarily reduces its fitness while increasing another organisms fitness with the expectation that the other organisms will act in a similar manner at a later time
reciprocal altruism
what are the benefits of sociality
-social aggregations provide defense
-the more animals there are in a group, the less likely an ind. within the group will be eaten; probability
-sociality brings males and females together and synchronizes reproductive behavior
