What is primate infanticide?
Infanticide in non-human primates occurs when an individual kills its own or another individual’s dependent young.
What is mammal infanticide?
In animals, infanticide involves the killing of young offspring by a mature animal of the same species, and is studied in zoology, specifically in the field of ethology. In this case individuals may even kill closely related offspring. Filial infanticide occurs when a parent kills its own offspring.
What is Gorilla infanticide?
In many social species, after the alpha male has been replaced or the group disintegrates, a female’s infant is at risk of infanticide by a male. Female gorillas have developed the rare strategy of secondary dispersal in which they transfer between reproductive groups during the limited time period between weaning an …
Do bonobos commit infanticide?
Closely related species that differ in infanticide and testes size include chimpanzees (males commit infanticide) versus bonobos (males have not been observed to kill offspring).
What species do infanticide?
Infanticide is rare in solitary or monogamous mammal species. Infanticide was found to be widespread, occurring in rodents including mice and squirrels, carnivores including lions and bears as well as in hippos, horses and even the white-throated round-eared bat.

Do monkeys eat their own babies?

In the 1915 study, primatologist and psychologist Robert Yerkes “reported the case of a captive rhesus macaque mother who carried her dead infant for five weeks,” and he suggested in the study that the mother’s behavior was a manifestation of maternal instinct, Fernández-Fueyo told Live Science in an email.
Why do animals commit infanticide?
The main culprit, biologists think, is the species’ social structure and reproductive strategy. Looking across hundreds of species, infanticide is more common in mammals when a few males must compete to reproduce with several females.
