 Famously good-looking parents like Tom Cruise and Katie Holmes, seen here with daughter Suri, are more likely to have girls than uglier couples. |

Single girls have always grumbled that good-looking men are difficult to find. But science may have just proved them right – because beautiful women are more likely to have daughters than their plainer counterparts, according to a study. As parents tend to pass on genes that determine looks, this could result in handsome men becoming rather thin on the ground. And it may also explain why many models have daughters who follow in their glamorous footsteps – such as Yasmin Le Bon, who is signed to the same modelling agency as daughter Amber, and Jerry Hall, whose daughters Elizabeth and Georgia Jagger have both taken to the catwalk. Dr Satoshi Kanazawa, of the London School of Economics, analysed data from a survey of 17,000 babies born in Britain in March 1958 and tracked them throughout their lives. At the age of seven, their attractiveness was rated by their teachers. When they reached 45, they were asked about the gender of any children they had. Those rated as attractive were equally likely to have a son or daughter as their first child – but the unattractive sorts were more likely to have a son. Put another way, the beautiful women were more likely to have daughters than those who were less blessed in the looks department, the journal Reproductive Sciences will report. A previous study of 2,000 Americans suggested that women are becoming more beautiful over the generations because attractive women have more children than plain ones – and a higher proportion of their offspring are girls. Dr Kanazawa believes that parents tend to produce children who benefit from their own attributes. Beauty, he says, is of more benefit to a woman than a man, and so it pays for attractive women to have daughters. But couples blessed with strength and aggression rather than looks are better off having boys, as these characteristics are of more use to males. (Read by Renee Haines.

單身女孩總是抱怨英俊的男人很難找。 也許現(xiàn)在已經(jīng)找到了它的科學(xué)根據(jù)，因?yàn)橐豁?xiàng)研究稱，漂亮女人比相貌普通的女人更容易生女孩。 由于父母通常會將決定相貌的基因遺傳給孩子，這可能會造成英俊的男人數(shù)量越來越稀少。 這也許可以解釋為什么許多模特兒的女兒都女承母業(yè)，步入星光大道，例如雅斯門?勒?邦的女兒安伯和她簽的是同一家模特兒經(jīng)紀(jì)公司，杰瑞?霍爾的女兒伊麗莎白和喬治亞?賈格爾也都成為了模特兒。 倫敦經(jīng)濟(jì)學(xué)院的金澤聰博士分析了一項(xiàng)對英國1.7萬人進(jìn)行的終身跟蹤調(diào)查數(shù)據(jù)，調(diào)查對象都是1958年3月在英國出生的。 這些人在7歲時，他們的老師對他們的吸引力做了評估。在他們45歲時，研究者向其詢問了他們所生的孩子的性別。 那些被評為“有魅力的”人頭胎生男生女的機(jī)會均等，但那些“沒有魅力的”人生兒子的幾率更大。 換句話說，根據(jù)《生殖科學(xué)》雜志的報(bào)道，漂亮的女人比那些長相平平的女人更容易生女孩。 先前一項(xiàng)涵蓋了2000名美國人的研究顯示，隨著人類一代又一代的更替，女性會變得越來越漂亮，因?yàn)槠僚吮乳L相普通的女人生的孩子更多，而且在她們的后代中女孩占的比例更大。 金澤博士認(rèn)為，父母通常會生出能受益于自身基因的孩子。他說，美貌對于女性而言比對于男性好處更多，因此漂亮女人生女兒是值得的。 比起長相好的夫婦，那些體力更強(qiáng)、更有進(jìn)取心的夫婦更容易生兒子，因?yàn)檫@些特質(zhì)對男性更有用。 相關(guān)閱讀 （中國日報(bào)網(wǎng)英語點(diǎn)津 陳丹妮 編輯：馮明惠） |
