Document Summary
Beneits of me having more money: i am richer. Costs of me having more money: my siblings are poorer. I care about my siblings because we are same genes so about as much as i care about myself. If my parents and i thought diferently about these cost and beneits there would be a conlict. Siblings are geneically related so r = a gene that causes an ofspring to take more resources now will reduce its own replicaion through future siblings natural selecion favors increase in genes. Ofspring should maximize by b(p) c(p) C(p) = # of future ofspring given up . All ofspring are geneically related to the parent by r = so parents feel that beneit because the future ofspring are weighted by so parents should maximize by b(p) c(p) We expect an evoluionary conlict between parents and ofspring over the levels of care. This can be resolved in many ways: parent wins, ofspring wins, compromise.
