Instead, Valenzuela postulates that mental activity alters the central nervous system in different ways at various levels. Research on mice, he says, shows...

To do so would enable researchers to pinpoint the particular genes that relate to a specific characteristic, such as a disposition toward a certain disease or physical attribute like blond hair...
