    August Weismann Embraces the Protozoa.Frederick B. Churchill - 2010 - Journal of the History of Biology 43 (4):767 - 800.
    This paper examines the contents and institutional context of August Weismann's long essay on Amphimixis (1891). Therein he presented detailed discussions of his on-going studies of reduction division and parthenogenesis, but more to the point, he included an elaborate examination of Émile Maupas's two major publications in protozoology. To understand the relevance of this part to the other two, the author briefly reviews highpoints in earlier nineteenth century protozoology and concludes that only in the mid-1870s and 1880s did protozoa add (...)

    The Guts of the Matter: Infusoria From Ehrenberg to Bütschli, 1838-1876. [REVIEW]Frederick B. Churchill - 1989 - Journal of the History of Biology 22 (2):189-213.
    We began our survey at a time when Ehrenberg's functional principles concerning the design of all organisms prevailed in interpreting the taxonomic place and internal structure of Infusoria. Other options existed, such as Dujardin's sarcode theory and Siebold's cellular analogy, but these were not persuasive for reasons both relevant to and in addition to the microscopic observations. By mid-century other considerations, including the continuing search for complex life cycles and manifestations of sex, dictated the microscopist's rendering of infusorians. Müller and (...)

    Recent Works in the History and Philosophy of Science Have Explored Anew the Possible Connection Between Science and Ethics. 1 They Follow a Well-Established Tradition That has Dogged Modern Science Since David Hume Questioned Whether a Moral Claim (Ie, an ''Ought'') Might Be Derived From a Factual Claim (Ie, an ''Is''). In the Post-Darwin Period, as Biologists Wrestled with Explanations for Evolution, Evo-Lutionary Ethics Became a Major Issue for Promoters of Species Descent.
