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.
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.
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 — .
A Natural History of Families Scott Forbes Published by Princeton University Press Forbes, Scott. A Natural History of Families. Princeton: Princeton University Press, Evolution is famously controversial, despite being as well established as any scientific theory.
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.
The evolution of murder Joshua Duntley, Ph.D. – The Richard Stockton College of New Jersey (e.g., infanticide of own children); (4) why people kill in Psychological adaptations for murder view the world through the lens of local culture, social environment, and . Keywords: KEYWORDS sexual mimicry, spotted hyenas, androgenization, genital masculinization, monomorphism, siblicide, infanticide, natural selection, adaptation Show All Female spotted hyenas (Crocuta crocuta) present an unsolved puzzle because they exhibit one of the most extraordinary genital morphologies of any mammal.
In More Than Kin and Less Than Kind, Douglas Mock tells us what scientists have discovered about this disturbing side of family dynamics in the natural world. Natural selection operates primarily for the benefit of individuals (and their genes).
