摘要:In 2017, three interdisciplinary workshops were held on whether and how biological discordancemight impact our views on species. Though the prompting focus of these workshopswas genealogical discordance, the precise sense of ‘discordance’ was left intentionallyambiguous. This was to encourage an examination of the question from many different perspectivesand to foster connections across disciplines. Participants included philosophers,historians, and other social scientists, alongside a range of biologists representing microbiology,population genetics, phylogenetics, invasion biology, herpetology, and ecology, amongother areas. Here, context is provided for those workshops and to help motivate why biologicaldiscordance generates useful interdisciplinary research problems, along with briefsummaries of the workshop papers included in this special issue.
