Atlas of cortical sulcal imprints on Pan endocasts

open access: yesJournal of Anatomy, EarlyView.
This comprehensive atlas documents the frequency, position, and variability of cortical sulcal imprints across 21 extant Pan endocasts, providing the first quantitative baseline for comparative paleoneurology. This atlas serves as a reference for distinguishing ancestral from derived features in hominin brain evolution.

Bonobos: the peaceful apes; here's what we can learn from our dark, hairy cousins

open access: yes, 2023
There are remarkable differences between chimpanzees and bonobos.Chimpanzees and bonobos are both equally closely related to us.Chimpanzees, bonobos, and humans live in fission-fusion societies that split up into small subgroups.Bonobos may cooperate ...

Ancient admixture from an extinct ape lineage into bonobos [PDF]

open access: yes, 2019
Admixture is a recurrent phenomenon in humans and other great ape populations. Genetic information from extinct hominins allows us to study historical interactions with modern humans and discover adaptive functions of gene flow.

Reduced bonobo MHC class I diversity predicts a reduced viral peptide binding ability compared to chimpanzees

open access: yesBMC Evolutionary Biology, 2019
Background The highly polymorphic genes of the major histocompatibility complex (MHC) class I are involved in defense against viruses and other intracellular pathogens. Although several studies found reduced MHC class I diversity in bonobos in comparison

A Year in the Bones: Investigating Bone Resorption Across a Reproductive Year in Wild Female Assamese Macaques

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Reproduction places considerable metabolic demands on females, particularly during pregnancy and lactation, when calcium homeostasis and bone metabolism are challenged. Urinary C‐terminal telopeptide of type I collagen (CTX‐I) offers a useful non‐invasive marker to assess bone resorption.

Socio-sexual behaviour in two groups of captive Bonobos (Pan paniscus): a description and functional analysis [PDF]

open access: yes, 2005
This study is an investigation into bonobo socio-sexual behaviour in two captive groups, Twycross in Leicestershire and Planckendael in Belgium. There are four main areas of emphasis and these are reconciliation, tension reduction, social bonding and ...

Bonobos respond aversively to unequal reward distributions. [PDF]

open access: yesProc Biol Sci
Inequity aversion (IA) is the resistance to unequitable rewards given similar investments and has been postulated as an important mechanism by which human cooperation thrives.

L’habituation des bonobos de la forêt de Manzano dans le Territoire de Bolobo (Province du Bandundu, RDC) : évolution du processus au regard du socio-écosystème

open access: yesRevue de Primatologie, 2014
L’habituation se définit comme l’assimilation d’observateurs par des animaux sauvages à des éléments neutres de l’environnement. Son évolution dépend des relations passées entre les populations locales et ces animaux, de l’organisation sociale de l ...

The evolutionary psychology of the human pointing gesture

open access: yesMind &Language, EarlyView.
The human pointing gesture is a species‐unique and species‐universal form of communication that depends on humans' especially powerful forms of cooperative cognition and motivation. I have previously hypothesized that the pointing gesture evolved as a behavioral tool empowering individuals to better coordinate their interdependent collaborative ...

The Hunting Behavior and Carnivory of Wild Chimpanzees [PDF]

open access: yes, 2014
The pursuit, capture and consumption of small- and medium-sized vertebrates appear to be typical of all chimpanzee (Pan troglodytes) populations, although large variation exists. Red colobus monkeys (Piliocolobus sp.) appear to be the preferred prey, but
