生物谷報道：人們常說上天是公平的，得到的越多，就可能失去越多,。然而最近一項研究表明幸運的卻會經(jīng)常降臨在一個人的身上，他可以擁有天使的臉龐和更加健康的身體,。
英國斯特林大學的研究人員近期做了一項調(diào)查研究,，結(jié)果表明相貌優(yōu)秀的人通常會擁有健康的身體，其原因則是：相貌優(yōu)秀是擁有良好基因的表現(xiàn),。研究人員通過人們對最協(xié)調(diào)和最不協(xié)調(diào)的臉部照片所產(chǎn)生的吸引力作出判斷,，得出的結(jié)論是：面部對稱的男性都更富有陽剛之氣，而面部對稱的女性則更具陰柔之美,。研究人員表示,，生物特性能夠說明很多問題，例如對稱性和陽剛,、陰柔的特性“都能體現(xiàn)抗病能力,，或者應對環(huán)境壓力的能力，而這也許意味著擁有這些特征的人將更加健康,。這項研究結(jié)果發(fā)表在5月7日出版的《共科學圖書館 綜合》上面,。(生物谷www.bioon.com)

Abstract
Background
Many animals both display and assess multiple signals. Two prominently studied traits are symmetry and sexual dimorphism, which, for many animals, are proposed cues to heritable fitness benefits. These traits are associated with other potential benefits, such as fertility. In humans, the face has been extensively studied in terms of attractiveness. Faces have the potential to be advertisements of mate quality and both symmetry and sexual dimorphism have been linked to the attractiveness of human face shape.
Methodology/Principal Findings
Here we show that measurements of symmetry and sexual dimorphism from faces are related in humans, both in Europeans and African hunter-gatherers, and in a non-human primate. Using human judges, symmetry measurements were also related to perceived sexual dimorphism. In all samples, symmetric males had more masculine facial proportions and symmetric females had more feminine facial proportions.
Conclusions/Significance
Our findings support the claim that sexual dimorphism and symmetry in faces are signals advertising quality by providing evidence that there must be a biological mechanism linking the two traits during development. Such data also suggests that the signalling properties of faces are universal across human populations and are potentially phylogenetically old in primates.
