This paper explores Charles Darwin's hypothesis of pangenesis through a popular and professional reception history. First published in The Variation of Animals and Plants under Domestication (1868), pangenesis stated that inheritance can be explained by sub-cellular "gemmules" which aggregated in the sexual organs during intercourse. Pangenesis thereby accounted for the seemingly arbitrary absence and presence of traits in offspring while also clarifying some botanical and invertebrates' limb regeneration abilities. I argue that critics largely interpreted Variation as an extension of On the Origin of Species by Means of Natural Selection (1859), while pangenesis was an extension of natural selection. Contrary to claims that pangenesis was divorced from natural selection by its reliance on the inheritance of acquired characters, pangenesis's mid nineteenth-century reception suggests that Darwin's hypothesis responded directly to selection's critics. Using Variation's several editions, periodical reviews, and personal correspondence I assess pangenesis popularly, professionally, and biographically to better understand Variation's impact on 1860s and 70s British evolutionism and inheritance.
There has never been a better time to create audio content than the present. Not only do most personal computers come with audio software like GarageBand (OSX) and VoiceRecorder (Win) already installed, free programs such as Audacity and LMMS can be readily downloaded online. This has opened up a variety of new project opportunities for instructors eager to incorporate digital humanities concepts and ideas into their classrooms. In multimodal communication courses foregrounding history, archive, and visual culture studies, the form of the audio guide offers a useful medium for students to create inventive and theoretically rigorous projects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
