夜猫子还是早起的鸟儿？基因来定夺

A new study suggests morning people are born, not made.

一项新的研究表明，早睡早起是与生俱来的特质，不是后天养成的。

Here's some good news for all you night owls desperately trying to get better at mornings - new research suggests that it's not your fault that you can't string a sentence together before 9am. You may simply be genetically predisposed to being more productive at night-time.

好消息!还在为晨起打不起精神抓狂的夜猫子们，新的研究表明，9点前连话都说不完整不怪你们啦，或许就是基因决定了你们晚上效率更高。

After investigating the genomes of fruit flies, researchers from the University of Leicester in the UK have identified nearly 80 genes that are linked to a preference for either 'morningness' or 'eveningness'. And although that may sound pretty unrelated to your own body clock, the team showed that most of these genes are found in mammals, too.

在调查了果蝇的基因染色体组后，英国莱斯特大学的研究人员鉴别出了80种和喜欢“早起早睡或是“晚起晚睡相关的基因。尽管这听起来和生物钟不甚相关，研究团队表明这些基因也大都可以在哺乳动物身上找到。

Previous research has demonstrated that most people find they're most productive either early in the day or late at night - a preference that's known as a 'chronotype'. And while a lot of studies have looked into the effects of this chronotype, there hasn't been much investigation into what actually causes these differences, up until now.
