(April 19, 2010) Robert Sapolsky looks at the biology of behavior through the ethological lens: observing animals in various natural environments, in their own language. He explores behavioral variety, the importance of gene environment interactions, experimental testing of fixed action patterns, the releasing of informational stimuli, and neuroethology.
