An examination of primate evolution and diet

Sexual dimorphism is a pervasive phenomenon among anthropoid primates comparative analyses over the past 30 years have greatly expanded our understanding of both variation in the expression of dimorphism among primates, and the underlying causes of sexual dimorphism. The study of extant primates therefore offers us priceless comparative models, which we can use to gain insights into tool use, behavioural ecology, phylogenetic relationships, diet, hunting, dispersal and cognition all crucial aspects of human evolution. Diet and primate evolution wild primates take most of the daily diet from plant sources, eating moderate to small amounts of animal source foods (asf) plant materials make up from 87% to 99. Primate behavior introduction the evolution of behavior some factors that influence social structure primatologists study the relationships between diet and behavior, they consider the benefits in terms of energy (calories) derived from various primate social behavior.

The ultimate driving factors responsible for the rapid evolution of brain size, body size, and craniodental anatomy at this stage of human evolution appear to have been major environmental changes that promoted shifts in diet and foraging behavior.

Drawing boundaries between diet categories is non-trivial as mentioned above, extreme diets are rare in nature instead, there is a spectrum of diets, and drawing lines or boundaries in the multi-dimensional dietary spectrum to distinguish between, say, frugivores and faunivores [faunivore = meat-eater] is a non-trivial problemthe reality that primates may frequently switch dietary categories. Evolution of dentition all primates express dietary plasticity, which means that they eat a wide variety of different foods in order to keep this varied diet, primates’ dentition, or teeth, have adapted in various ways.

The role of diet in primate evolution most primates are highly arboreal animals and carry out most activities in the canopy of tropical forest trees fossil evidence suggests that the earliest primates evolved from small insectivores, initially attracted into the canopy by pollinating insects.

Feeding ecology in apes and other primates focuses on evolutionary perspectives of the complex interactions between the environment, food sources, physiology, and behavior in primates this highly interdisciplinary volume provides a benchmark to assess dietary alterations that affected human evolution by putting the focus on the diet of hominid. We note that primate g s contains social (social learning, tactical deception), technical (tool use, innovation) and ecological (extractive foraging, diet breadth) intelligence components, supporting a battery of hypotheses regarding the factors driving brain evolution [6,7,12–17,20,26], but not the hypotheses that social or ecological. The evolution of primate locomotion and body configuration primates first evolved from the trees of tropical forests, later to the ground through the times of promisians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes.

A gradual shift in diet for these primates to mostly frugivorous in the middle of this period to mostly herbivorous towards the end of it, but with considerable variance between specific primate species as to lesser items in the diet, such as insects, meat, and other plant foods.
