The Middle Miocene ape Pierolapithecus catalaunicus exhibits extant great ape-like morphometric affinities on its patella: inferences on knee function and evolution. [PDF]

open access: yesPLoS ONE, 2014
The mosaic nature of the Miocene ape postcranium hinders the reconstruction of the positional behavior and locomotion of these taxa based on isolated elements only.

Apes and agriculture

open access: yesFrontiers in Conservation Science, 2023
Non-human great apes – chimpanzees, gorillas, bonobos, and orangutans – are threatened by agricultural expansion, particularly from rice, cacao, cassava, maize, and oil palm cultivation.

A cross-species study of gesture and its role in symbolic development: Implications for the gestural theory of language evolution

open access: yesFrontiers in Psychology, 2013
Using a naturalistic video database, we examined whether gestures scaffolded the symbolic development of a language-enculturated chimpanzee, a language-enculturated bonobo, and a human child during the second year of life.

The manual skills and cognition that lie behind hominid tool use [PDF]

open access: yes, 2004
Tool use is an important aspect of being human that has assumed a central place in accounts of the evolutionary origins of human intelligence. This has inevitably focused a spotlight on any signs of tool use or manufacture in great apes and other non ...

A potential diagnostic pitfall in ST elevation: Acute pulmonary embolism or ST‐segment elevation myocardial infarction

open access: yesAnnals of Noninvasive Electrocardiology, 2022
The diagnosis of acute pulmonary embolism (APE) is a great challenge for physicians due to its nonspecific symptoms, and often missed or misdiagnosed as acute coronary syndrome.

OpenApePose, a database of annotated ape photographs for pose estimation

open access: yeseLife, 2023
Because of their close relationship with humans, non-human apes (chimpanzees, bonobos, gorillas, orangutans, and gibbons, including siamangs) are of great scientific interest.

Functional Implications of Human-Specific Changes in Great Ape microRNAs. [PDF]

open access: yesPLoS ONE, 2016
microRNAs are crucial post-transcriptional regulators of gene expression involved in a wide range of biological processes. Although microRNAs are highly conserved among species, the functional implications of existing lineage-specific changes and their ...

Imitation recognition in great apes [PDF]

open access: yesCurrent Biology, 2008
SummaryHuman infants imitate not only to acquire skill, but also as a fundamental part of social interaction [1–3]. They recognise when they are being imitated by showing increased visual attention to imitators (implicit recognition) and by engaging in so-called testing behaviours (explicit recognition).

In the Zone: Towards a Comparative Study of Flow State in Primates [PDF]

open access: yesAnimal Behavior and Cognition, 2023
Flow is an altered state of feeling ‘in the zone’ when fully absorbed in a challenge and is associated with positive affective state (feelings). Despite almost five decades of research, Flow has not yet been recognized in non- human animals, despite ...
