Wild red jungle fowl, progenitors of the modern chicken, crowd a pen near Statesboro, Georgia. Remnants of a population collected in north-central India in the early 1960s, these birds may be the last of their kind—genetically speaking. As humans push farther into the wild bird s South Asian habitat, the chickens they bring with them interbreed with jungle fowl, polluting their genomes.
