Psychology: Red enhances human performance in contests
TLDR
Across a range of sports, it is found that wearing red is consistently associated with a higher probability of winning, indicating not only that sexual selection may have influenced the evolution of human response to colours, but also that the colour of sportswear needs to be taken into account to ensure a level playing field in sport.

Ecology, feeding competition and social structure in baboons
TLDR
An ecological model of baboon social structure is presented which incorporates the effects of female-female competition, male-male competition, and predation pressure, and potentially accounts for wide variability in group size, group structure and social relationships within the genus Papio.

Embodied cognitive evolution and the cerebellum
  • R. Barton
  • Psychology, Medicine
  • Philosophical Transactions of the Royal Society B…
  • 5 August 2012
TLDR
It is argued that cognitive evolution is most effectively understood as the elaboration of specialized systems for embodied adaptive control, including sensory–motor and cognitive specializations underpinning such skills. Expand
Neocortex size and behavioural ecology in primates
  • R. Barton
  • Biology, Medicine
  • Proceedings of the Royal Society of London…
  • 22 February 1996
TLDR
It is confirmed that neocortex size and social group size are positively correlated once phylogenetic associations and overall brain size are taken into account, and among diurnal haplorhines its size is positively correlated with the degree of frugivory. Expand
Habitat use and resource availability in baboons
TLDR
Multiple regression analysis of total time spent in each quadrat revealed that apparent preferences for particular vegetation zones were a result of the spatial coincidence of these zones with sleeping sites and waterholes, emphasizing the importance of controlling for confounding factors in studying the determinants of habitat selection. Expand
Evolutionary radiation of visual and olfactory brain systems in primates, bats and insectivores.
TLDR
It is concluded that activity timing, diet and habitat have each played a role in the evolutionary radiation of mammalian sensory systems, but with varying effects in the different taxa. Expand
Maternal investment, life histories, and the costs of brain growth in mammals
TLDR
It is shown that evolutionary changes in pre- and postnatal brain growth correlate specifically with duration of the relevant phases of maternal investment (gestation and lactation, respectively), and there is support for the hypothesis that the rate of fetal brain growth is related to the energy turnover of the mother. Expand
Phylogeny and metabolic scaling in mammals.
TLDR
The lack of evidence for a predominant scaling exponent in these analyses suggests that general models of metabolic scaling, and macro-ecological theories that depend on them, have little explanatory power. Expand
Dietary and foraging strategies of baboons.
TLDR
This paper develops and test multivariate models of the basis of diet selection for populations of montane and savannah baboons and indicates convergence on lower degrees of variation than exist in superficial foodstuff profiles. Expand
Visual specialization and brain evolution in primates
  • R. Barton
  • Biology, Medicine
  • Proceedings of the Royal Society of London…
  • 22 October 1998
TLDR
It is shown that, among primates, brain size variation is associated with visual specialization, and this results suggest that the relatively large brains of frugivorous species are products of selection on the ability to perceive and select fruits using specific visual cues such as colour. Expand
