Animal infanticide is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs. The practice has been observed in many species throughout the animal kingdom, especially primates (primate infanticide) but including microscopic rotifers, insects, fish, amphibians, birds and mammals. [3]
Infanticide in non-human primates occurs when an individual kills its own or another individual's dependent young. Five hypotheses have been proposed to explain infanticide in non-human primates : exploitation , resource competition , parental manipulation, sexual selection , and social pathology .
Offspring of both sexes are evicted from the group upon reaching puberty. It can be seen in many species of primates, including the gelada baboon, [1] the patas monkey, savanna baboon, [2] sun-tailed monkey, golden snub-nosed monkey, and the hamadryas baboon. [3] There are costs and benefits for individuals living in one-male groups.
Infanticide is observed to be the major cause of mortality in various mammals. Polyandry is thought to evolve from their offspring's vulnerability to infanticide. [ 31 ] There is evidence that polyandry is an effective strategy that is adapted by many to increase their offspring survival through the avoidance of male infanticide.
Furthermore, it is prevalent in spider monkeys, [1] wild Barbary macaques (Macaca sylvanus) and many other primates. [11] In basically all major primate taxa, aggression is used by the dominant males when herding females and keeping them away from other males. [1] In hamadryas baboons, the males often bite the females' necks and threaten them. [12]
Infanticide (or infant homicide) is the intentional killing of infants or offspring. Infanticide was a widespread practice throughout human history that was mainly used to dispose of unwanted children, [1]: 61 its main purpose being the prevention of resources being spent on weak or disabled offspring. Unwanted infants were usually abandoned to ...
