Of parasites, dinosaurs, and other model animals

Elaine Charwat has been on a journey into the attic storerooms behind the scenes of the Museum to discover 19th-century wax models of parasites. A strange occupation you might think, but it’s all part of her doctoral research programme with the Arts and Humanities Research Council to learn about the use of models and replicas in science, past and present. In the podcast above Elaine meets Mark Carnall, Zoology Collections Manager at the OUMNH, who talks about the differences between models and the thousands of specimens he looks after, and Dr Péter Molnár, Assistant Professor of Biological Sciences at the University of Toronto, who offers important insights into current research using mathematical models.

Different types of models and replicas are everywhere in the Museum, and they tell us much about the organisms they represent or reconstruct, but even more about processes in research and science. Made to communicate and produce data, these larger-than-life objects are as fascinating as their subjects…
