Behaviorism is a theory of learning that states all behaviors are learned through conditioned interaction with the environment. Thus, behavior is simply a response to environmental stimuli. The behaviorist theory is only concerned with observable stimulus-response behaviors, as they can be studied in a systematic and observable manner.

Meaning “ancient beaver” (Castoridae is the family that includes beavers), the several known species of Palaeocastor most likely looked like a cross between a modern North American beaver and a gopher and lived only in what is now the American Midwest.

Lungfish - Classification, Evolution, Adaptations: The separation of Dipnoi as a discrete group is based largely on the skull bones, the endoskeleton of the paired fins, and the teeth. The living orders are distinguishable mainly by the number of lungs. Subclass Dipnoi has two living orders: Ceratodontiformes and Lepidosireniformes.beaver (Palaeocastor) using a consistent series of strokes with its teeth, the burrows are nearly equally divided between dextral and sinistral traces.
