WebIn chapter 4 we saw how applying the Price equation to studying inclusive fitness raised an issue of the appropriate level of causal analysis; should one simply ask when inclusive fitness is positive, thereby ignoring questions over whether a particular behavior is altruistic or selfish, for example, or should we “drill down” to look at ...
