Chimpanzee Cognitive Control [PDF]

open access: yesCurrent Directions in Psychological Science, 2015
Cognitive-control processes are a feature of human cognition. Recent comparative tests have shown that some nonhuman animals might share aspects of cognitive control with humans. Two of the executive processes that constitute cognitive control are metacognition and self-control; here, recent experiments with chimpanzees are described that demonstrated

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Prey preferences of the chimpanzee (Pan troglodytes)

open access: yesEcology and Evolution, 2021
The common chimpanzee Pan troglodytes is the closest extant relative of modern humans and is often used as a model organism to help understand prehistoric human behavior and ecology. Originally presumed herbivorous, chimpanzees have been observed hunting

Human brain evolution and the "Neuroevolutionary Time-depth Principle:" Implications for the Reclassification of fear-circuitry-related traits in DSM-V and for studying resilience to warzone-related posttraumatic stress disorder. [PDF]

open access: yes, 2006
The DSM-III, DSM-IV, DSM-IV-TR and ICD-10 have judiciously minimized discussion of etiologies to distance clinical psychiatry from Freudian psychoanalysis.

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

open access: yesBiological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Language-trained animals: a window to the "black box" [PDF]

open access: yes, 2012
Animals have to process quantity of information in order to take decisions and adapt their behaviors to their physical and social environment. They have to remember previous events (learning), to cope with their internal (motivational and emotional ...

A Novel Chimpanzee Adenovirus Vector with Low Human Seroprevalence: Improved Systems for Vector Derivation and Comparative Immunogenicity

open access: yesPLoS ONE, 2012
Recombinant adenoviruses are among the most promising tools for vaccine antigen delivery. Recently, the development of new vectors has focused on serotypes to which the human population is less exposed in order to circumvent pre-existing anti vector ...

Cross-comparison of the genome sequences from human, chimpanzee, Neanderthal and a Denisovan hominin identifies novel potentially compensated mutations

open access: yesHuman Genomics, 2011
The recent publication of the draft genome sequences of the Neanderthal and a ~50,000-year-old archaic hominin from Denisova Cave in southern Siberia has ushered in a new age in molecular archaeology.

Teaching varies with task complexity in wild chimpanzees

open access: yes, 2020
Understanding social influences on how apes acquire tool behaviors can help us model the evolution of culture and technology in humans. Humans scaffold novice tool skills with diverse strategies, including the transfer of tools between individuals ...
