'Puppy Dog Eyes' May Have Evolved Just to Make Humans Melt - And It's Working
狗的“無辜眼神”可能是為了萌化人類才進化出來的，顯然這招很奏效

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個東西時是故意做出那種表情的嗎？你知道那種閃耀著渴望的乞求的眼神嗎？她要什么你都愿意給，對吧？

It turns out that our response to canine looks of longing or love may be the very reason dogs can make them.
研究發(fā)現(xiàn)我們對犬類這種渴求或愛的眼神的回應可能導致狗狗有那種眼神。

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.
新的研究發(fā)現(xiàn)做這種表情牽動的面部肌肉只有狗狗有，狼就沒有，這就表明我們的毛茸茸的好朋友專門為了跟人類溝通而進化出了這種能力。

"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.
樸茨茅斯大學的行為心理學家Juliane Kaminski說：“研究結(jié)果表明人類馴化狗狗時無意識的選擇偏好導致狗狗有了富有表情的眉毛?！?/div>

"When dogs make the movement, it seems to elicit a strong desire in humans to look after them. This would give dogs that move their eyebrows more, a selection advantage over others and reinforce the 'puppy dog eyes' trait for future generations."
“狗狗做出這種表情時會激起人類強烈的照顧它們的欲望，這就促使狗狗更多地抖動眉毛，這也成為了一種選擇優(yōu)勢，使這種‘撒嬌眼神’成為了遺傳給后代的特征?！?/div>

Previously, Kaminski and her team have demonstrated that dogs do actually make facial expressions as a means of communicating with humans, by studying their behaviour when a human was facing towards them, compared to facing away.
此前Kaminski和她的團隊證實了狗狗的確會把面部表情作為和人類溝通的一種工具，他們研究了人面向狗狗和面向別處時狗狗的行為。

The team found that dogs used facial expressions far more when the human was looking at them.
這個團隊發(fā)現(xiàn)人看著狗狗時它們的面部表情更多。
