ANIMAL BEHAVIOR: Definition
The study of behavior encompasses all the movements and sensations by which organisms mediate their relationship with their environment -- physical, biotic and social.
• Movements and sensations
• Mediate relationship with environment

The cuckoo chick, just hours after it hatches and before its eyes have opened, evicts the eggs of its foster parents from the nest.
The parents, responding to the stimulus of the cuckoo chick's wide-gaping mouth, feed the chick, unaware that it is not related to them.

NATURE - NURTURE• Stephen Pinker. ''The Blank Slate: The Modern Denial of Human Nature'‘.
• Tabula rasa (Latin: blank slate) refers to the epistemological thesis that individuals are born without built-in mental content and that their knowledge comes from experience and sensory perception. Implication: all human minds are equal because they are equally blank, equally free of innate, genetically shaped, abilities and behaviors.
• Consider child-rearing: children's characters are shaped by their genes, by their peer group and by chance experiences; parents cannot mold their children's nature, nor should they wish to, any more than they can redesign that of their spouses. Those little slates are not as blank as they may seem.
• If genes do contribute substantially to the development of personal characteristics such as intelligence and personality, then many wonder if this implies that genes determine who we are. No: Misunderstanding of development.
