    為什么狗狗無辜眼神讓人難以抗拒?

    新浪科技訊 北京時間7月2日消息,據國外媒體報道,養狗的人想必都很熟悉傳說中無辜可愛的“狗狗眼”,而科學家近日找到了狗狗們進化出這種表情的原因。

      狗的眼周之所以進化出了這些新肌肉,是為了更好地與人類交流,研究人員將狗與狼的解剖結構和行為表現進行了比較,并分析了它們在過去數千年間的變化,分析結果顯示,狗與狼的面部結構十分相似,只有眼睛上方的結構不同,狗的眼睛上方有一塊小肌肉,讓它們能夠高高揚起眉毛內側;而狼卻沒有這塊肌肉。

      揚起眉毛內側的這個動作能夠讓狗狗的眼睛看上去更大、更像個嬰兒,從而激起人類的呵護欲,證據明確顯示,狗在被人類從狼馴化成家養動物后,便逐漸進化出了這塊使其能夠抬起眉毛內側的肌肉。

      通過對比狗與狼的行為,在與人類接觸的兩分鐘內,狗抬起眉毛內側的頻率比狼更多、幅度也更大,狗狗的眉毛之所以如此具有表現力,可能是因為人類會下意識地偏心能露出這種表情的狗狗,從而影響了馴化過程中的自然選擇。

      當狗狗露出這種表情時,似乎會在人們心中激起強烈的、想要照顧它們的欲望,因此狗狗露出這種表情越多,就越容易在自然選擇中占上風,其后代的‘狗狗眼’特征也會不斷得到強化。(葉子)
