In his study of how the sociopolitical milieu and scientific thinking intersect, Persell (affiliation unspecified) analyzes the impact of France's defeat in the Franco-Prussian War on the ascendancy of anti-Darwinian evolutionists among Third Republic scientists. In their affirmation of the <'e>lan of French science and Republican reform ideology (e.g. on criminality, morality, and eduction for women), neo-Lamarckians Giard, Delage, Le Dantec, and Lanessan managed to not only skew Darwin's seminal theory but Lamarck's notion of acquired characteristics as well. Includes an illustration of each scientist, and both English and French references. Annotation c. by Book News, Inc., Portland, Or.
