Edsall, John T.
Edsall here continued his discussion with Crick on the interaction of heredity and environment in the formation of intelligence, an issue brought to the forefront of public debate in the late 1960s by the writings of William Shockley and Arthur Jensen. In particular Edsall here responded to Crick's call for a "Twins Institute" that would encourage parents of identical twins to give up one twin for adoption as a way of expanding the pool of subjects for studies on identical twins raised separately. To scientists, such studies were ideally suited to distinguish the effects of heredity and environment on human development.
