Document Summary

Evolution acts at the level of genes & genes that contribute to fitness will get replicated more often, in frequency in successive generations. ^ people refer to this concept as the selfish gene . The following table represents 4 different social behaviours. Recipient = the one on the receiving end of the behaviour performed. The well-being of each can improve or decline based on the behaviour performed. Ex. teaching billy (teammate) how to play hockey. Short run, this may seem like a cost b/c you devote time and energy to teaching billy. Long run, this benefits you b/c your team will perform better and win more games. Others" fitness can increase our own fitness. Adaptations must increase success of the gene (not for the good of the group") Adaptations are for the good of the gene. Helping the worst team player may help the group but in evolutionary terms, that"s not a good reason.
