Fermentation Technology as a Driver of Human Brain Expansion

The mechanisms by which external fermentation can mediate the evolution of increased brain size, as well as a reduction in gut size, by increasing the bioavailability of macroand micronutrients while reducing digestive energy expenditure are detailed.

Hominin Paleodiets: The Contribution of Stable Isotopes

Stable isotope ratio analysis is now regularly used to investigate early hominin diets based upon the principle that ‘you are what you eat’. Analysis of collagen from Neanderthals and anatomically

Guts and Brains : An Integrative Approach to the Hominin Record

Guts and Brains discusses the key variables at stake in such a question, including the relationship between brain size and diet, diet and social organization, and large brains and the human sexual division of labour.

Identification of differences in human and great ape phytanic acid metabolism that could influence gene expression profiles and physiological functions

Differences in the physiological levels of phytanic acid in humans and great apes are identified and this is causally related to their gut anatomies and microbiomes, which could contribute to cross-species and sex-specific differences in human and great ape transcriptomes.

The Possible Role of Body Temperature in Modulating Brain and Body Sizes in Hominin Evolution

It is suggested that modest deviations in body temperature might allow for substantive changes in brain and body parameters and may prove amenable to an increased number of neurons, a higher brain-to-body mass ratio and fewer hours expended on feeding activities when the temperature is lowered.

The co-evolution of life and organics on earth: Expansions of energy harnessing

Abstract The organic matter was absent prior to planetesimal formation (4.6 Gyr) but at present abundant in planetary environments. The aim of this study was to combine information about the organic

The Culinary Origins of Human Occupation: Part 1 (Motor and Process Skills)

This paper proposes that human occupation cannot be understood in a biologically valid evolutionary sense without an appreciation of energy metabolism as the primary cause of human occupational evolution; that the authors' hominid ancestors evolved into occupational human beings in response to clearly identifiable climatological events that threatened their food supply.

Evolutionary biology of ape and monkey feeding and nutrition

This chapter discusses several unique aspects of primate feeding biology, including the evolution of large brains, trichromatic color vision, and tool use, and moves on to evaluate the fundamental problems of plant fiber and chemical defenses and concludes by arguing that primate adaptations for J.E. species adaptations, abundance, and richness since the Miocene are justified.



The Expensive-Tissue Hypothesis: The Brain and the Digestive System in Human and Primate Evolution

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

Comparative Behavior of Red and Giant Pandas in the Wolong Reserve, China

The energetic and mechanical advantages associated with increased size suggest that the giant panda evolved from a small bamboo-eating animal resembling the red panda, which is a relatively non-selective feeder that barely chews its food.

Dietary Hypotheses and Human Evolution

The microwear on fossil hominids appears to rule out certain diets that have been proposed for them, and a biomechanical analysis makes it clear that the changes in jaw and tooth form are subtle and outside the resolution given by present understanding of cranial function.
