Primate Blood Groups and Evolution

The Evolution of Cooperation in Primate Groups

Bare skin, blood and the evolution of primate colour vision.

We investigate the hypothesis that colour vision in primates was selected for discriminating the spectral modulations on the skin of conspecifics, presumably for the purpose of discriminating emotional states, socio-sexual signals and threat displays. Here we show that, consistent with this hypothesis, there are two dimensions of skin spectral modulations, and trichromats but not dichromats are...

Primate Evolution

The Primates are the order of mammals that includes ourselves along with other well known creatures such as chimpanzees, baboons and lemurs. The non-human members of the orders show many similarities to us in areas of social behaviour, language, tool-use and anatomy; and study of these animals gives us important insights into the origins of these features in ourselves. This lecture will briefly...

Blood groups: In Health and Diseases

ABO blood type antigens are polymorphic, inherited structures presented on the surface of red blood cells. Although ABO blood group antigens is the most important antigens in transfusion medicine, its main role is not clearly clarified. Correlation between ABO blood group and susceptibility to certain infectious and non-infectious diseases is a controversial issue. Since, lack of blood type ant...
