Molecular genetics of speciation and human origins.
The major histocompatibility complex (MHC) plays a cardinal role in the defense of vertebrates against parasites and other pathogens. In some genes there are extensive and ancient polymorphisms that have passed from ancestral to descendant species and are shared among contemporary species. The polymorphism at the DRB1 locus, represented by 58 known alleles in humans, has existed for at least 30...

This compositional project began with the idea of extending the relationship between human gestures and sound by electronic means. From that germin...
متن کاملThe taxonomic status of the Italian Sparrow — Passer italiae (Vieillot 1817): Speciation by stabilised hybridisation? A critical analysis
Since its description the taxonomic status of the Italian Sparrow Passer italiae (Vieillot 1817) has changed repeatedly according to the speciation concepts applied. Due to external similarities with hybrid sparrow individuals the hypothesis that italiae is a stabilised hybrid form between Passer domesticus (L. 1758) and P. hispaniolensis (Temm. 1820) has deeply influenced the discussion althou...
متن کاملNot the Nice Sparrow
—We began our studies of House Sparrow (Passer domesticus) biparental care in the mid-1990s by applying the classic Margaret Morse Nice field technique of color-banding individuals. Over the ensuing summers, we slowly accumulated quantitative provisioning records for 100 broods, even as we commenced a series of experimental manipulations. Provisioning data showed parental fitness, as expressed ...
