Conservation of myeloid surface antigens on primate granulocytes.
Monoclonal antibodies reactive with myeloid cell surface antigens were used to study evolutionary changes in granulocyte surface antigens from primate species. Certain of these granulocyte membrane antigens are conserved in phylogenetically distant species, indicating the potential functional importance of these structures. The degree of conservation of these antigens reflects the phylogenetic ...

متن کاملMolecular evolution of rickettsia surface antigens: evidence of positive selection.
The Rickettsia genus is a group of obligate intracellular parasitic alpha-proteobacteria that includes human pathogens responsible for the typhus disease and various types of spotted fevers. rOmpA and rOmpB are two members of the "surface cell antigen" (Sca) autotransporter (AT) protein family that may play key roles in the adhesion of the Rickettsia cells to the host tissue. These molecules ar...
متن کاملPrimate 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...
متن کاملEvolution of primate cognition
Comparative analysis of the behavior of modern primates, in conjunction with an accurate phylogenetic tree of relatedness, has the power to chart the early history of human cognitive evolution. Adaptive cognitive changes along this path occurred, it is believed, in response to various forms of complexity; to some extent, theories that relate particular challenges to cognitive adaptations can al...
