Behavior Shared Through Extragenetic Transmission
For a behavior to be considered cultural it must be shared extragenetically; that is, it must be taught. If a trained dog is introduced to a puppy that doesn't know not to eliminate in a house, it cannot teach it not to do so. A particularly intelligent puppy might eventually learn not to eliminate in people's houses by observing the older dog, but no active teaching would have taken place.
Contrast this with an observed group of Macaque monkeys. Some scientists wanted to learn about eating behaviors in Macaque monkeys, so they put some sweet potatoes on a beach near where they lived. The sweet potatoes got sandy and, as the monkeys disliked dirty food, they would spend some time picking the sand off. One young female, however started taking her potatoes to a freshwater pool to rinse off. She showed the others how to do so as well. The scientists then threw wheat on the sand, hoping the monkeys would spend more time picking the food out so they would have more time to observe them. The same young female just scooped up handfuls of wheat and sand and dumped them in the water. The sand sank and the wheat floated, which she ate. This practice also quickly spread through the group. This is what humans could call a proto-cultural behavior. It is learned, it involves concepts and generalisations, and it is taught. There is only one thing missing.

Famous quotes containing the words behavior and/or shared:
“Excessive attention, even if it’s negative, is such a powerful “reward” to a child that it actually reinforces the undesirable behavior. You need to learn restraint, to respond to far fewer situations, to ask yourself questions like, “Is this really important?” “Could I let this behavior go?” “What would happen if I just wait?” “Could I lose by doing nothing?””
—Stanley Turecki (20th century)
“Prose—it might be speculated—is discourse; poetry ellipsis. Prose is spoken aloud; poetry overheard. The one is presumably articulate and social, a shared language, the voice of “communication”; the other is private, allusive, teasing, sly, idiosyncratic as the spider’s delicate web, a kind of witchcraft unfathomable to ordinary minds.”
—Joyce Carol Oates (b. 1938)
