 In the life cycles that are most immediately familiar, processes that mark the end of one life cycle and the beginning of another of the same kind of individual—processes such as material bottlenecking, sexual reproduction, and multiplication—temporally coalesce. In the life cycles of other individuals, such as ferns and scyphozoan jellyfish, these processes are sometimes dispersed, function differently, or are absent (Godfrey-Smith 2016a, 2016b). Such cases call for a corresponding sophistication of accounts of reproduction and, as James Griesemer says, these complexities in life cycles may
