Les tissus du cerveau sont une extension metabollique, mais il n'existe pas de correlation significative entre le taux metabolique relatif de base et la taille relative du taille chez les humains et autres mammiferes a encephale. L'apport en graisses animales dans la nourriture est essentiel dans l'evolution du cerveau humain 
Energetics, Life History, and Human Brain Evolution
TLDR
This chapter reviews the various hypotheses that have been proposed to explain how humans and other encephalized species were able to afford an increase in brain size and the expensive brain framework, which provides a model for combining strategies.
Fifty Years of Looking at Human Evolution
  • C. Jolly
  • History, Medicine
    Current Anthropology
  • 2009
TLDR
Celle-ci inclue notamment l'observation des primates, domaine de recherche de l'auteur de la recherches en anthropologie concernant l'evolution humaine.
Theories of human evolutionary trends in meat eating and studies of primate intestinal tracts
TLDR
Comparative studies of primate intestinal tracts do not support the hypothesis that switching to meat eating permitted an increase in brain size and hence the emergence of modern man, and it is likely that, while meat assumed a more important role in hominid diet, it was not responsible for any major evolutionary shift.
Exceptional Evolutionary Divergence of Human Muscle and Brain Metabolomes Parallels Human Cognitive and Physical Uniqueness
Accelerated evolution of the human brain and muscle metabolomes reflects our unique cognitive and physical capacities.
The evolution of the meningeal vascular system in the human genus: From brain shape to thermoregulation
TLDR
This study is aimed at investigating the relationships between endocranial morphology and endocrinial vessels in modern humans and to analyze the pattern of heat dissipation through the endocraticanial surface in fossil specimens.
Evolutionary implications for human brain development and fatty acid intake
TLDR
The human gut is the only organ which shows a reduced size and energy demand relative to that expected for the authors' body size, however a reduced gut size is only possible with a shift to a ‘high quality’ diet.
Why cattle feed much and humans think much – New approach to confirm the expensive tissue hypothesis by molecular data
TLDR
It is hypothesize that the activity of marker proteins expressed both in brain and alimentary tract should parallel functional morphology in organs at the molecular level, and that the reverse concentration of CA-II in saliva and brains of cattle and primates might be the first molecular evidence of the validity of the “expensive tissue hypothesis”.
Metabolic Acceleration in Human Evolution.
  • K. Isler
  • Biology, Medicine
    Cell metabolism
  • 2016
TLDR
New data on daily energy expenditure in great apes are presented and it is shown that the metabolic rate increased during human evolution.
The Expensive-Tissue Hypothesis in Vertebrates: Gut Microbiota Effect, a Review
TLDR
Research relating to and discusses the potential influence of gut microbiota on the Expensive-Tissue Hypothesis, which states that the metabolic requirement of relatively large brains is offset by a corresponding reduction of the other tissues, such as gut size.

Morphology of the gastrointestinal tract in primates: Comparisons with other mammals in relation to diet
TLDR
Three categories of dietary adaptation are recognized according to the distinctive structural and biochemical features of animal matter, fruit, and leaves respectively, and the predominance of only one in the diets of most species.
Brain Size and Its Relation to the Rate of Metabolism in Mammals
TLDR
Brain size depends on the habits of a mammal: it is larger in arboreal species and in species that feed on vertebrates, seeds, or fruit, and it is smaller in terrestrial species thatFeed on grass or the leaves of woody plants.
Energy Metabolism, Brain Size and Longevity in Mammals
  • M. Hofman
  • Medicine, Biology

TLDR
The maximum potential life span of a mammal was found to be proportional to the product of its degree of encephalization and the reciprocal of its metabolic rate per unit weight.
Early hominid hunting and scavenging: the role of meat as an energy source
TLDR
This paper argues that meat may actually have been a relatively marginal source of sustenance for early hominids, because physiological limits to total protein intake, scarcity of fat in most African ungulates, and comparatively high levels of protein in many plant foods, acted together to maintain their total meat intakes at modest levels, particularly during seasonal or inter-annual periods of resource stress.
Relative brain size and metabolism in mammals.
TLDR
Comparisons of the relation between brain and body weights among extant mammals show that brain sizes have not increased as much as body sizes, but primates also use a larger proportion of their total energy reserves for their brains.
The Relationship between Summated Tissue Respiration and Metabolic Rate in the Mouse and Dog
TLDR
The nature of the axial gradients in Planaria and their relation to anteroposterior dominance, polarity, and symmetry and the effects of certain depressing agents on intracellular oxidation of indicators in Hydra are studied.
Diet and Gut Morphology in Primates
TLDR
More precise subdivisions are necessary, although these gross categories still have a use, especially in correlative studies; the two extremes are best labelled, however, “faunivory” and “folivor”, respectively.

TLDR
Consideration of energetic costs of brain allow the prediction of growth rates in hominid taxa and an examination of the implications for life-history strategy and foraging behaviour.
Organ Weights in Primates and Other Mammals
In mammals the weight of the heart, kidney, lungs, and other organs can be related to total body weight through power laws (allometry). Weights of primate organs are analyzed by this technique.
