Abstract
In this essay I sketch 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 valid supporters, and encouraged him to publish his theoretical reflections. In his Gedanken zur Descendenz- und Vererbungstheorie, which appeared between 1893 and 1903 in five series in the Biologisches Zentralblatt, Emery developed a very personal account applying the concept of determinants to problems like atavism, sexual dimorphism, speciation, geographical isolation, transmission of characters, and putting forward, as early as 1903, the idea of ‘genetic program’.
