The relationship between genes and social behavior has historically been construed as a one-way street, with genes in control. Recent analyses have challenged this view, by discovering broad alterations in the expression of human genes as a function of differing socio-environmental conditions. The emerging field of social genomics has begun to identity the types of genes subject to social regulation, the biological signaling pathways mediating those effects, and the genetic polymorphisms that moderate socioenvironmental influences on human gene expression.
ColeS.W. et al. (2007). (See References). This study provided the first indication that social factors might systematically regulate human genome activity in the immune system, and it pioneered novel strategies for identifying the social signal transduction pathways involved.
