The evolution and adaptation of infanticide and siblicide

Save Lion cubs may be killed by males replacing other males in the pride. Ovicide is the analogous destruction of eggs. The practice has been observed in many species throughout the animal kingdom, especially primates primate infanticide. These include microscopic rotifersinsectsfishamphibiansbirds and mammals.

The evolution and adaptation of infanticide and siblicide

Similarly, studies of birds, fish, amphibians, and invertebrates demonstrate egg and larval mortality in these species, a phenomenon directly analogous to infanticide in mammals. In this collection, Hausfater and Hrdy draw together work on animal and human infanticide and place these studies in a broad evolutionary and comparative perspective.

The evolution and adaptation of infanticide and siblicide

Infanticide presents the theoretical background and taxonomic distribution of infanticide, infanticide in nonhuman primates, infanticide in rodents, and infanticide in humans. It examines closely sex allocation and sex ratio theory, surveys the phylogeny of mammalian interbirth intervals, and reviews data on sources of egg and larval mortality in a variety of invertebrate and lower vertebrate species.

Dealing with infanticide in nonhuman primates, two chapters critically examine data on infanticide in langurs and its broader theoretical implications. By reviewing sources of infant mortality in populations of small mammals and new laboratory analyses of the causes and consequences of infanticide, this work explores such issues as the ontogeny of infanticide, proximate cues of infants and females which elicit infanticidal behavior in males, the genetical basis of infanticide, and the hormonal determinants.

Hausfater and Sarah Blaffer Hrdy, through their selection of materials for this book, evaluate the frequency, causes, and function of infanticide. Historical, ethnographic, and recent data on infanticide are surveyed.

Infanticide summarizes current research on the evolutionary origins and proximate causation of infanticide in animals and man.

As such it will be indispensable reading for anthropologists and behavioral biologists as well as ecologists, psychologists, demographers, and epidemiologists. Glenn Hausfater was professor at the division of biological sciences at the University of Missouri-Columbia.The topic of infanticide has been a staple theorem of sociobiology ever since this discipline — the study of social behavior from an evolution- ary perspective — .

Most people are familiar with the dismal statistics, showing how a large fraction of Americans at all educational levels do not accept the theory of evolution [], how efforts to teach evolution often fail to have an impact [], and how constant vigilance is required to keep evolution in the public.
