Ethological imprinting determines behavioural perception in all animals who possess it.

This book attempts to identify the missing elements of ontogenetic plasticity, by demonstrating:

. That ethological imprinting exists in all mammals and most other higher-order species. . That the evolutionary advantage imprinting provides is an advantage to evolution itself, reducing difference-penalties so groups accept and propagate beneficial mutations in real time. . That quantifiable ecological imprinting processes exist in humans, and can be specified.
