Dogs and modern gray wolves share a recent wolf ancestor from which dogs were domesticated. Noting that dogs tend to have darker irises than gray wolves do, Akitsugu Konno et al. presented facial images of dogs with a range of iris colors to human participants, who rated the dogs' personality traits and their own attitudes toward the dogs. On the basis of their findings, Konno et al. concluded that the dog-wolf iris pattern may be an effect of human selection for a positively perceived trait during domestication.
Which choice best describes data from the table that support Konno et al.'s conclusion?
Participants rated the dogs in images 3 and 6 as friendlier than the dogs in images 14 and 20 and indicated that they were more willing to interact with or keep the dogs in the former two images than the dogs in the latter two images.
