Inferential Communication: Bridging the Gap Between Intentional and Ostensive Communication in Non-human Primates

open access: yesFrontiers in Psychology, 2022
Communication, when defined as an act intended to affect the psychological state of another individual, demands the use of inference. Either the signaler, the recipient, or both must make leaps of understanding which surpass the semantic information ...

The early bonobo gets the juice? The evolutionary roots of pre-crastination in bonobos (Pan paniscus)

open access: yesAnimal Behavior and Cognition, 2022
Pre-crastination refers to the propensity to initiate tasks at the earliest possible moment. Research with human adults has found that some individuals consistently chose to transport a nearby object a further distance rather than delay initiation of the

Sleeping site sharing between Aotus griseimembra (Mammalia, Primates) and Coendou quichua (Mammalia, Rodentia) in a lowland inter-Andean valley in Colombia [PDF]

open access: yesNeotropical Biology and Conservation
Tree cavities used as sleeping sites are a limited resource for arboreal mammals. The shared use of arboreal cavities as sleeping sites between Neotropical mammals is rarely observed and has been little studied.

Novel insights into the genetic diversity of Balantidium and Balantidium-like cyst-forming ciliates [PDF]

open access: yes, 2013
Balantidiasis is considered a neglected zoonotic disease with pigs serving as reservoir hosts. However, Balantidium coli has been recorded in many other mammalian species, including primates. Here, we evaluated the genetic diversity of B.

Predictors of orbital convergence in primates: A test of the snake detection hypothesis of primate evolution [PDF]

open access: yes, 2011
Traditional explanations for the evolution of high orbital convergence and stereoscopic vision in primates have focused on how stereopsis might have aided early primates in foraging or locomoting in an arboreal environment. It has recently been suggested

Primates [PDF]

open access: yesCurrent Biology, 2012
SummaryHomo sapiens is just one of some 400 extant species allocated to the mammalian order Primates, originally proposed by Linnaeus in the mid-18th Century. As George Gaylord Simpson tartly noted in his seminal 1945 classification of the class Mammalia: “The primates are inevitably the most interesting of mammals to an egocentric species that belongs

Comparative metabolomics in primates reveals the effects of diet and gene regulatory variation on metabolic divergence. [PDF]

open access: yes, 2014
Human diets differ from those of non-human primates. Among few obvious differences, humans consume more meat than most non-human primates and regularly cook their food.

Accelerated Evolution of the ASPM Gene Controlling Brain Size Begins Prior to Human Brain Expansion [PDF]

open access: yes, 2004
Primary microcephaly (MCPH) is a neurodevelopmental disorder characterized by global reduction in cerebral cortical volume. The microcephalic brain has a volume comparable to that of early hominids, raising the possibility that some MCPH genes may have ...
