Default 'Bastard' Mouse Steals Poison-Resistance Gene

“House mice in Germany and Spain have acquired resistance against a group of widely used rodent poisons through hybridization with a different species, the Algerian mouse. The finding suggests hybridization may play a more important role in animal evolution than researchers believed.”
“The study shows that the role of hybridization in animal evolution has been underestimated, Tautz says. Evolutionary biologist Jerry Coyne of the University of Chicago in Illinois agrees that the paper is important. "It is very well documented, and it shows that hybridization is one more mechanism by which variation arises, that natural selection then acts upon," he says. But because hybridization has mostly negative consequences, Coyne believes it's unlikely to be an important mechanism in animal evolution. "This is big news because it is rare,” he says.”
