Searching for the Clocks of Metamorphosis

  • William Etkin
Part of the Perspectives in Neuroendocrine Research book series (PNR, volume 2)


At the beginning of my scientific career, I became caught up in the problem of tadpole metamorphosis: how does the animal “know” when to start and how to time the sequence of events involved? This search led, of course, into endocrinology, then into neuroendocrinology and into numerous side paths. The call by the Editors for my contribution to this series I interpret in terms of an informal accounting of the interplay of ideas, personalities, and events that propelled and buffetted me in this journey.
