One of the two major theories regarding the evolution of intelligence in primates is that feeding strategies determine mental development. Evidence for this theory is reviewed and related to extractive foraging, which is the act of locating and/or processing embedded foods such as underground roots and insects or hard-shelled nuts and fruits. It is shown that, although only cebus monkeys and chimpanzees in the wild use tools in extractive foraging, many other species of mammals (including… 
A short note on extractive foraging behavior in gray snub-nosed monkeys.
The results seem to do not support the hypothesis that EF serves to secure additional resources during lean times in marginal or seasonal habitats, and it is suggested R. brelich should be considered as an extractive forager.
Tool Use, Aye-Ayes, and Sensorimotor Intelligence
The results support the view that aye-ayes do not achieve stage 6 comprehension of tool use, but rather may use trial-and-error learning to develop tool-use behaviors.
Extractive foraging on hard‐shelled walnuts and variation of feeding techniques in wild Japanese macaques (Macaca fuscata)
It is suggested that walnut feeding by Japanese macaques is not only by brute force but requires the acquisition of at least one of four cracking methods for the achievement of complete cracking, and females need to compensate for their physical inferiority by increasing walnut manipulations.
The conditions for tool use in primates: implications for the evolution of material culture.
It is concluded that strong mutual tolerance was a key factor in the explosive increase in technology among hominids, probably intricately tied to a lifestyle involving food sharing and tool-based processing or the acquisition of large, shareable food packages.
Development of skilled detection and extraction of embedded prey by wild brown capuchin monkeys (Cebus apella apella).
The developmental sequence of skill acquisition goes counter to the preceding logical sequence of foraging process and it is suggested that searching components present greater challenges than handling components in extractive foraging.
Extractive foraging and tool-aided behaviors in the wild Nicobar long-tailed macaque (Macaca fascicularis umbrosus)
Seven complex manipulative behaviors that include six extractive foraging behaviors, and teeth flossing, in a population of Nicobar long-tailed macaques are reported, suggesting that Nicobarlong-tails macaques have a high level of sensorimotor intelligence which helps to evolve such innovative foraging solutions.
Manipulation and Tool Use in captive Yellow-Breasted Capuchin Monkeys (Cebus xanthosternos) - eScholarship
The frequency of time each animal was involved with manipulative events was not correlated to the number of tool-using events displayed by them, even when the males only (the most frequent manipulators) were analyzed, going against the idea that tool use in Cebus is a product of both manipulative propensities and tendency to use objects.
The Role of Terrestriality in Promoting Primate Technology
Comparison evidence among primates supports the hypothesis that the terrestriality premium may have been a major pacemaker of hominin technological evolution and seems to be crucial for acquiring and maintaining complex tool variants, particularly expressions of cumulative technology, within a population.
Chimpanzee Intelligence Is Heritable
Current views on hunter-gatherer nutrition and the evolution of the human diet.
A brief summary of the study of the evolution of human nutrition as it has specifically pertained to data coming from living hunter-gatherers is provided, in order to bridge the disciplines that are currently invested in research on nutrition and health among foraging populations.


Distribution Patterns of Tropical Plant Foods as an Evolutionary Stimulus to Primate Mental Development
It is hypothesized that the element of predictability associated with the spatial and temporal distribution patterns of plant foods in tropical forests has served to stimulate mental development in primates taking much of their food from the first trophic level.
Lemur Social Behavior and Primate Intelligence
It seems likely that the rudiments of primate society preceded the growth ofPrimate intelligence, made it possible, and determined its nature.
A developmental model for the evolution of language and intelligence in early hominids
It is proposed that the common ancestor of the great apes and man displayed rudimentary forms of late sensorimotor and early preoperational intelligence similar to that of one- to four-year-old children, which arose as adaptations for extractive foraging with tools, which requires a long postweaning apprenticeship.
Optimal Foraging and Hominid Evolution: Labor and Reciprocity
It is argued that cooperative foraging incorporating information exchange may have preceded tool use during the course of hominid evolution and set the stage for the emergence of reciprocal exchanges of information and resources.
The authors measured the cranial capacities of 225 species of bats from 14 families including all families and genera previously studied by Stephan and Pirlot (1970) to confirm their conclusions about encephalization and refine their first order correlation with dietary specializations.
The ecological role of the callitrichidae: a review.
It is believed that the marmosets and tamarins are members of a guild of exudate feeders in which plant exudates are an important component of the diet and within this framework of a primate foraging guild that they can best understand many of their morphological and behavioral adaptations.
Encephalization and quantitative brain composition in bats in relation to their life-habits.
A quantitative analysis of the brains of 43 bat species is presented and gives a clearer view of Chiropteran progressiveness or primitiveness: the insectivorous forms occupy the least advanced, although most specialized, level; the vampires, the carnivorous species and the flying foxes are at the top of the scale.
