Ape duos and trios: spontaneous cooperation with free partner choice in chimpanzees [PDF]
PeerJ, 2014 The purpose of the present study was to push the boundaries of cooperation among captive chimpanzees (Pan troglodytes). There has been doubt about the level of cooperation that chimpanzees are able to spontaneously achieve or understand.

Multimodal communication by captive chimpanzees (Pan troglodytes) [PDF]
Animal Cognition, 2009 Many studies have shown that apes and monkeys are adept at cross-modal matching tasks requiring the subject to identify objects in one modality when information regarding those objects has been presented in a different modality. However, much less is known about non-human primates' production of multimodal signaling in communicative contexts.

Core promoter short tandem repeats as evolutionary switch codes for primate speciation [PDF]
, 2015 Alteration in gene expression levels underlies many of the phenotypic differences across species. Because of their highly mutable nature, proximity to the +1 transcription start site (TSS), and the emerging evidence of functional impact on gene ...

Apes communicate about absent and displaced objects: methodology matters [PDF]
, 2013 Displaced reference is the ability to refer to an item that has been moved (displaced) in space and/or time, and has been called one of the true hallmarks of referential communication.

The biomechanical importance of the scaphoid-centrale fusion during simulated knuckle-walking and its implications for human locomotor evolution [PDF]
, 2020 © 2020, The Author(s). Inferring the locomotor behaviour of the last common ancestor (LCA) of humans and African apes is still a divisive issue. An African great-ape-like ancestor using knuckle-walking is still the most parsimonious hypothesis for the ...

Molecular cytotaxonomy of primates by chromosomal in situ suppression hybridization [PDF]
, 1990 A new strategy for analyzing chromosomal evolution in primates is presented using chromosomal in situ suppression (CISS) hybridization. Biotin-labeled DNA libraries from flow-sorted human chromosomes are hybridized to chromosome preparations of ...

Efficient search for a face by chimpanzees (Pan troglodytes)
Scientific Reports, 2015 The face is quite an important stimulus category for human and nonhuman primates in their social lives. Recent advances in comparative-cognitive research clearly indicate that chimpanzees and humans process faces in a special manner; that is, using ...

Aging and sex affect soluble alpha klotho levels in bonobos and chimpanzees
Frontiers in Zoology, 2018 Background Throughout life, physiological homeostasis is challenged and the capacity to cope with such challenges declines with increasing age. In many species, sex differences exist in life expectancy.
