Red junglefowl are under threat from domesticated chickens that want to mate with them, a new study shows. These wild birds, the ancestors of domesticated chickens, risk losing their genetic diversity because they are breeding with farmed chickens that putter around their natural habitat. 

If this crossbreeding continues, it could threaten junglefowl’s survival in the future, which would likely have knock-on effects for their domestic counterparts.
