ABSTRACT
To begin to appreciate why this is so, it is helpful to consider a fascinating experiment carried out in the spring of 1937 in Altenburg, Austria. It was conducted by two zoologists, Konrad Lorenz and Niko Tinbergen, early founders of the discipline of ethology-the study of animals in their natural setting. They were fascinated by the idea of innate species-speci›c behavior patterns-actions inherent to individual species in the same way as tigers have speci›c claws or sharks have unique teeth. Sometime earlier, while walking along Jesus Lane in Cambridge, they had discussed their theories and conjectures. Now in Austria, on a 3-month spring break, they decided to investigate further.
