WebLife history theory is an analytical framework designed to study the diversity of life history strategies used by different organisms throughout the world, as well as the causes and results of the variation in their life cycles. It is a theory of biological evolution that seeks to explain aspects of organisms' anatomy and behavior by reference to the way that their … Weblife-history strategies (e.g., Gittleman, 1994).

WebThe life history of a species is the pattern of survival and reproduction events typical for a member of the species (essentially, its lifecycle). Life history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction. One tradeoff is between number of offspring produced ... WebLife history theory suggests that due to constraints and trade-offs among life history traits, species fall along a continuum of slow to fast life histories (Charnov, 1993; Reynolds et al., 2001; Stearns, 1983, 1992). Slow life histories describe those species that have slower growth, lower reproductive output, long gestation times, later ages ...

WebJan 1, 2024 · Life history theory predicts that individuals in harsh and unpredictable environments will favor having more offspring sooner because such fast strategies would favor the chance that (a) one will reproduce successfully before dying and (b) at least some of one’s offspring will possess the genotypic or phenotypic qualities needed to survive in …
