The genes that predispose people to attain higher levels of education have been in decline over the past 80 years, and researchers are suggesting that they’re now under negative selection, which could have a big impact on our species in the coming centuries.
在过去80年里,人们选择更高水平教育基因的倾向不断下降,研究人员认为如今这种基因已处于负选择,在接下来的几百年里可能对我们人类这个物种产生重要影响。
A study involving more than 100,000 people in Iceland found that those who carry the genes for longer education time were less likely to have a big family, which means the smartest people in the room were actually contributing less to the Icelandic gene pool.
在冰岛一个10万人参与的研究显示,携带“选择更高水平教育基因”的人拥有一个大家庭的可能性更小,这也就是说,他们其中最聪明的人反而对冰岛基因库的贡献较小。
"As a species, we are defined by the power of our brains. Education is the training and refining of our mental capacities," said Kari Stefansson, CEO of Icelandic genetics firm deCODE, which ran the study. "Thus, it is fascinating to find that genetic factors linked to more time spent in education are becoming rarer in the gene pool."
这项研究的发起人,冰岛遗传学公司deCODE的首席执行官Kari Stefansson说“作为一个物种,我们的力量皆是大脑所赐,而教育则是锻炼重塑我们心智的手段,因此探寻到底是什么原因使得基因库中的在教育上花费更过时间的基因变得稀缺是很有意义的。”
