The form of exploitation in non-human primates most attributable to adult females is when non-lactating females take an infant from its mother (allomothering) and forcibly retain it until starvation. This behavior is known as the "aunting to death" phenomenon; these non-lactating female primates gain mothering-like experience, yet lack the ...
He highlighted their peaceful communal lifestyle and the high frequency of sexual interactions. A student of Junichiro Itani, he was a professor at Ryukyu University [1] and at the Primate Research Institute of Kyoto University. In 1973, he founded the first bonobo study center, at Wamba, Luo Reserve. It is the oldest bonobo research area and ...
Formerly the bonobo was known as the "pygmy chimpanzee", despite the bonobo having a similar body size to the common chimpanzee. The name "pygmy" was given by the German zoologist Ernst Schwarz in 1929, who classified the species on the basis of a previously mislabeled bonobo cranium, noting its diminutive size compared to chimpanzee skulls.
Infants in bonobo societies are often involved in sexual behaviour. [78] Immature male bonobos have been recorded initiating genital play with both adolescent and mature female bonobos. Copulation-like contact between immature bonobo males and mature female bonobos increases with age and continues until the male bonobo has reached juvenile age.
Ape Cognition and Conservation Initiative is a great ape sanctuary and scientific research facility in Des Moines, Iowa.The facility was announced in 2002 and received its first ape residents in 2004, conceived of as the Great Ape Trust, [1] or Iowa Primate Learning Sanctuary, [2] launched in part by the primatologist Sue Savage-Rumbaugh and Des Moines businessman Ted Townsend.
Sexual swelling, sexual skin, or anogenital tumescence refers to localized engorgement of the anus and vulva region of some female primates that vary in size over the course of the menstrual cycle. [ 1 ] [ 2 ] [ 3 ] Thought to be an honest signal of fertility , [ 4 ] male primates are attracted to these swellings; preferring, and competing for ...
[28] [29] In both chimpanzee and bonobo social groups, high ranking alpha males sire approximately half of the offspring within their social group. [39] [40] More research needs to be done addressing how reproductive skew affects paternal care and infant-male relationships in non-human primates including chimpanzees and bonobos.
Genital-genital rubbing: This is sexual activity in which one animal rubs his or her genitals against the genitals of another animal. This is stated to be the "bonobo's most typical sexual pattern, undocumented in any other primate". [117] [118] Inter-species mating: Some animals opportunistically mate with individuals of another species. [119]
