Body size and intelligence in hominoid evolution
Great apes and humans are the largest-brained primates. Aside from a few extinct subfossil lemurs, they are also the largest in body mass. Body size is a key aspect of a species’ biology, a large organism having different energetic, ecological, and physical constraints than a small one. Brain size, in so far as it determines abilities to acquire, process, and act on information, is also a key a...
متن کاملALTERATION OF T-LYMPHOCYTE SUBPOPULATIONS IN SUBACUTE AND CHRONIC BRUCELLOSIS
Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...
متن کاملUric acid, hominoid evolution, and the pathogenesis of salt-sensitivity.
Humans have elevated serum uric acid as a result of a mutation in the urate oxidase (uricase) gene that occurred during the Miocene. We hypothesize that the mutation provided a survival advantage because of the ability of hyperuricemia to maintain blood pressure under low-salt dietary conditions, such as prevailed during that period. Mild hyperuricemia in rats acutely increases blood pressure b...
متن کاملHominoid seminal protein evolution and ancestral mating behavior.
Hominoid mating systems show extensive variation among species. The degree of sexual dimorphism in body size and canine size varies among primates in accordance with their mating system, as does the testes size and the consistency of ejaculated semen, in response to differing levels of sperm competition. To investigate patterns of evolution at hominoid seminal proteins and to make inferences re...
متن کاملA SURVEY OF CELLULAR IMMUNITY, TOTAL T-LYMPHOCYTE, T-ACTIVE , B-LYMPHOCYTE A ND T-CELL FUNCTION IN RELATION TO PHYTOHEMAGGLUTININ (PHA) IN THALASSEMIC PATIENTS
The aim of this study was to evaluate the immune system and lymphocyte function in 41 Iranian β-thalassemic patients and 50 controls, ages ranging from 2 to 18 years. The patients consisted of 20 splenectomized and 21 non-splenectomized patients. They were treated with Desferal, and had received repeated blood transfusion. Laboratory investigations included measurement of total T lymphocyt...
