 Initially, Eldredge and Gould (1972) were quite explicit that they did not see their model as entailing a new type of selection. They straightforwardly wrote “we postulate no ‘new’ type of selection” (Eldredge &amp; Gould 1972: 112). But in 1975, the paleontologist and evolutionary theorist Steven M. Stanley dubbed Eldredge and Gould’s population-level selection process a form of species selection, and by 1977 the inventors of PE concurred. They wrote that they nonetheless understood species selection as representing “no more than the operation of natural selection at higher levels” (Gould &amp; Eldredge 1977: 139), but still, this interpretation presents a challenge to one typical way of instantiating the dominant model of natural selection.
