The Evolution of the Primate, Hominid and Human Brain
نویسنده
چکیده
A major questions arises in paleontology, anthropology and archeology, how did primates, hominids and humans develop a large brain [1-4]? Most mammals and early primates had a small brain, approximately 0.1% of total weight. Brain growth was limited by epitheliochorial placentation and inefficient mechanisms for transporting nutrition from mother to fetus, nutrients had to pass through five tissues layers [1-4]. How was this surmounted to permit the expanding brain among primates, hominids and humans? This question is addressed in this review.

Social life, evolution of intelligence, behaviour and human brain size
Social life is one of the most critical factors of the evolution of the behavior of non-human primates and humans. Several factors, such as an increase in brain size, adaptive modules, and grooming, are related to the complexities of social groups. Although some scientists have mentioned foraging as a rival hypothesis for the evolution of behavior, in this research, we tried to investigate the ...
متن کاملWidespread Genomic Signatures of Natural Selection in Hominid Evolution
Selection acting on genomic functional elements can be detected by its indirect effects on population diversity at linked neutral sites. To illuminate the selective forces that shaped hominid evolution, we analyzed the genomic distributions of human polymorphisms and sequence differences among five primate species relative to the locations of conserved sequence features. Neutral sequence divers...
متن کاملEarly hominid brain evolution: a new look at old endocasts.
Early hominid brain morphology is reassessed from endocasts of Australopithecus africanus and three species of Paranthropus, and new endocast reconstructions and cranial capacities are reported for four key specimens from the Paranthropus clade. The brain morphology of Australopithecus africanus appears more human like than that of Paranthropus in terms of overall frontal and temporal lobe shap...
متن کاملFrontal Feedback Model
The frontal feedback model argues that the sudden appearance of art and advancing technologies around 40,000 years ago in the hominid archaeological record was the end result of a recent fundamental change in the functional properties of the hominid brain, which occurred late in that brain’s evolution. This change was marked by the switching of the driving mechanism behind the global, dynamic f...
متن کاملMetabolic correlates of hominid brain evolution.
Large brain sizes in humans have important metabolic consequences as humans expend a relatively larger proportion of their resting energy budget on brain metabolism than other primates or non-primate mammals. The high costs of large human brains are supported, in part, by diets that are relatively rich in energy and other nutrients. Among living primates, the relative proportion of metabolic en...
