你的朋友会改变你的智商,从基因层面
Researchers from Berlin analysed the characteristics of a number of genes among a group of healthy adolescents, and compared the results with intelligence scores and various neurological traits. The researchers found a strong relationship between the epigenetic modifications of one particular gene and general IQ, suggesting our experiences not only affect the wiring of our brain, but the very way our genes function at a basic level. For example, in times of high stress, such as a persistent threat of violence or poor nutrition, physiological changes in the organism can tweak your genes by adding or removing a chemical group that effectively locks them down or opens them up. These edits can also go the other way. It's possible that showing infants ample affection, such as frequent cuddles, just might modify the expression of their genes in the same way. In turn, such changes can subtly influence a range of characteristics that can have drastic knock-on effects, altering the course of everything from how your immune system functions to how much you earn. |
