'Puppy Dog Eyes' May Have Evolved Just to Make Humans Melt - And It's Working 狗的“无辜眼神”可能是为了萌化人类才进化出来的，显然这招很奏效 You know how when your dog wants something, she makes that face? You know the one - all beseeching, with eyes that seem to positively quiver with longing? You'd give her anything, right? 你知道你的狗狗想要某个东西时是故意做出那种表情的吗？你知道那种闪耀着渴望的乞求的眼神吗？她要什么你都愿意给，对吧？ It turns out that our response to canine looks of longing or love may be the very reason dogs can make them. 研究发现我们对犬类这种渴求或爱的眼神的回应可能导致狗狗有那种眼神。 New research has found that the facial muscles involved in making these expressions can only be found in dogs, not wolves - suggesting our furry best friends evolved the ability specifically to communicate with humans. 新的研究发现做这种表情牵动的面部肌肉只有狗狗有，狼就没有，这就表明我们的毛茸茸的好朋友专门为了跟人类沟通而进化出了这种能力。 "The findings suggest that expressive eyebrows in dogs may be a result of human unconscious preferences that influenced selection during domestication," said behavioural psychologist Juliane Kaminski of the University of Portsmouth. 朴茨茅斯大学的行为心理学家Juliane Kaminski说：“研究结果表明人类驯化狗狗时无意识的选择偏好导致狗狗有了富有表情的眉毛。” |
