Abstract

Behavioural phenotypes have been explained by genetic and environmental factors (E) and their interaction. Here we suggest a rethinking of the E factor. Passively incurred environmental influences (Epass) and actively copied information and behaviour (Eact) may be distinguished at shared and non-shared level. We argue that Eact underlies mutation and selection and is the base of gene-independent heritability.
