  1. On the Legitimacy of the Darwinian Theory – August Weismann's First Creed.Charlotte Weissman - 2013 - Science in Context 26 (1):173-179.
    ArgumentIn his inaugural lecture, “On the Legitimacy of the Darwinian Theory,” August Weismann followed closely in Darwin's footsteps, but provided at the same time an outline of the essentials of his future theory of heredity, development, variation, and speciation. This was Weismann's first support of the evolutionary theory, and it shows his commitment to natural selection as the mechanism of evolution. For Weismann, “Darwin's Theory” meant natural selection. Natural selection, and more generally selectionism, became Weismann's major explanatory principle for evolutionary (...)

  • A Historical Taxonomy of Origin of Species Problems and Its Relevance to the Historiography of Evolutionary Thought.Koen B. Tanghe - 2017 - Journal of the History of Biology 50 (4):927-987.
    Historians tend to speak of the problem of the origin of species or the species question, as if it were a monolithic problem. In reality, the phrase refers to a, historically, surprisingly fluid and pluriform scientific issue. It has, in the course of the past five centuries, been used in no less than ten different ways or contexts. A clear taxonomy of these separate problems is useful or relevant in two ways. It certainly helps to disentangle confusions that have inevitably (...)

  • Of germ-plasm and zymoplasm: August Weismann, Carlo Emery and the debate about the transmission of acquired characteristics.Ariane Dröscher - 2015 - History and Philosophy of the Life Sciences 36 (3):394-403.
    In this essay I discuss the contents and the context of Italian zoologist and entomologist Carlo Emery’s discussion of the germ-plasm theory. August Weismann considered him one of his very few creditable supporters, and encouraged him to publish his theoretical reflections. In his Gedanken zur Descendenz- und Vererbungstheorie, which appeared between 1893 and 1903 as a series of five essays in the journal Biologisches Zentralblatt, Emery developed a very personal account, applying the concept of determinants to problems like atavism, sexual (...)
