Abstract

Organic selection (the Baldwin Effect) by which an environmentally elicited phenotypic adaptation comes under genotypic control following selection was proposed independently in 1896 by the psychologists James Baldwin and Conwy Lloyd Morgan and by the paleontologist Henry Fairfield Osborn. Modifiedforms of organic selection were proposed as autonomization by Schmalhausenin 1938, as genetic assimilation by Waddington in 1942, and as an explanation for evolution in changing environments or for speciation by Matsuda andWest-Eberhard in the 1980s. Organic selection as a mechanism mediating proximate environmental effects on the evolution of morphology and behaviour is the topic of this essay. Discussion includes the context in which organicselection was proposed, Lamarckian or neo-lamarckian implications of organic selection, Waddington's experimental studies demonstrating the existenceand efficacy of genetic assimilation, stabilizing selection and norms of reaction favoured by Schmalhausen, and Matsuda's search for a mechanism of organic selection in endocrine changes and in heterochrony.
