Infanticide: Comparative and Evolutionary Perspectives by Glenn Hausfater

By Glenn Hausfater

contemporary box experiences of a number of mammalian species display an incredibly excessive frequency of infanticide - the killing of unweaned or in a different way maternally established offspring. equally, reports of birds, fish, amphibians, and invertebrates display egg and larval mortality in those species, a phenomenon at once analogous to infanticide in mammals. during this assortment, Hausfater and Hrdy draw jointly paintings on animal and human infanticide and position those experiences in a large evolutionary and comparative perspective.Infanticide provides the theoretical heritage and taxonomic distribution of infanticide, infanticide in nonhuman primates, infanticide in rodents, and infanticide in people. It examines heavily intercourse allocation and intercourse ratio thought, surveys the phylogeny of mammalian interbirth periods, and reports info on resources of egg and larval mortality in quite a few invertebrate and reduce vertebrate species. facing infanticide in nonhuman primates, chapters significantly research facts on infanticide in langurs and its broader theoretical implications. via reviewing resources of boy or girl mortality in populations of small mammals and new laboratory analyses of the motives and outcomes of infanticide, this paintings explores such concerns because the ontogeny of infanticide, proximate cues of babies and women which elicit infanticidal habit in men, the genetical foundation of infanticide, and the hormonal determinants.Hausfater and Sarah Blaffer Hrdy, via their number of fabrics for this e-book, evaluation the frequency, motives, and serve as of infanticide. old, ethnographic, and up to date info on infanticide are surveyed. "Infanticide" summarizes present examine at the evolutionary origins and proximate causation of infanticide in animals and guy. As such it will likely be critical examining for anthropologists and behavioral biologists in addition to ecologists, psychologists, demographers, and epidemiologists.
