The shared past of a trait, no matter how superficially dissimilar, or the current similarities of a trait, even when there is no shared evolutionary past, can tell us much about the developmental processes, environments to which they have accommodated over their deep history. It also suggests as yet unsuspected physiological substrate.

in A&O we position our inquiry by treating the CREATION of art, its EXPRESSION (sometimes termed “realization”), and its RECEPTION by a viewer, as TRAITS with causes and consequences subject to change in evolutionary and developmental time.
The INTEGRATIVE BIOLOGY of BEHAVIOR involves the coordinated activities of four broad areas (as biologists study them): DEVELOPMENT, ECOLOGY, EVOLUTION, and PHYSIOLOGY and how they are brought to bear on BEHAVIOR (“DEEP ETHOLOGY”)
