Better smelling through genetics: mammalian odor perception.

Abstract excerpt

The increasing availability of genomic and genetic tools to study olfaction-the sense of smell-has brought important new insights into how this chemosensory modality functions in different species. Newly sequenced mammalian genomes-from platypus to dog-have made it possible to infer how smell has evolved to suit the needs of a given species and how variation within a species may affect individual olfactory...
