近来科学家们一项研究显示,基因定夺你是夜猫子还是早起的鸟儿,这是怎么回事?

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

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.

"The rhythm of life is such that for many people the economic or social call to start a new day comes hours before the endogenous call from the body clock. This creates a clock dysfunction that is not only reflected in temporal disorientation and sleep problems, but also in conditions such as obesity, mental illness, cardiovascular disease and cancer," said team member Eran Tauber.
