If electromagnetic fields affected living systems, there had to be a point in time where the electromagnetic field was converted into the language of biology. When we hear something, for example, the sound does not travel from the ear to the brain. Rather, the sound impinges on specialized cells in the ear and the presence of the acoustic energy causes movement of particular cell processes that result in the opening of ion channels in the cell’s membrane that, in turn, alter the membrane potential of the cell, resulting in movement of an electrical signal along a nerve to the brain resulting in the subjective sensation of sound. This pattern is common to the way the body detects each factor in the environment—the body transduces the environmental factor into its own language, and initiates an appropriate response. It must, I thought, also be the case for electromagnetic fields.
