Various histocompatibility genes confer susceptibility to almost all infectious and autoimmune diseases in mammals (and other vertebrates). Why hasn't evolution by natural selection eliminated these bad genes? We are conducting experiments designed to elucidate which evolutionary processes are responsible for maintaining the unprecedented genetic diversity of histocompatibility (MHC) genes. To address these questions we utilize interdisciplinary approaches involving immunology, host-parasite coevolution, genetics, behavior, sexual selection and kin selection. Our unique approach includes examining components of fitness of rodents in seminatural conditions, a methodology that has proven to be an extremely sensitive assay for exploring phenotypes that are largely undetectable by other methods. The sensitive nature of our fitness assays has proven highly successful in demonstrating adverse effects on mammalian health and performance from suspected toxins, mutations and other treatments.
