摩西·西夫: 早期生活经历如何写入DNA

早期生活经历如何写入DNA

摩西·西夫是表观遗传学领域的先驱，他研究生物如何对其基因组重新编码，以应对压力和缺乏食物等社会因素。 他的研究表明，从母体传递到后代的生化信号告诉孩子他们将要生活在什么样的世界，这改变了基因的表达。 “DNA不仅仅是一系列字母，它不只是一个脚本。” 西夫说。 “DNA是动态的电影，我们的经历正在被写入DNA”。

Early life experiences trigger chemical changes that influence how genes are expressed, affecting lifelong health and behavior. In one striking study, rat pups licked more by their mothers grew up less stressed and more resilient. Mammals, including humans, inherit not just DNA but also epigenetic 'marks' that prepare them for the world their mothers anticipate. These changes can explain why social stress, poverty, or even natural disasters leave lasting imprints on future generations.
