Evolution and Learning: The Baldwin Effect Reconsidered
Edited by Bruce H. Weber and David J. Depew. Cambridge, MA: MIT Press, 2003. 341 pp. Cloth, $50.00.

The Baldwin effect was not called the Baldwin effect until it was almost 60 years old. In 1953, George Gaylord Simpson published an article in the journal Evolution using that phrase as a title, and thus the effect (or, as Simpson declares, the "factor, principle, or hypothesis, as you will," Simpson, 1996, p. 100) acquired a name. The original proposal of this effect was made nearly simultaneously by J. Mark Baldwin, C. Lloyd Morgan, and H. F. Osborn in separate articles published in 1896.
