We all know bugs are important in the function of ecosystems but did you know about their importance in the world of forensics, or in the study of physics? This week on Terra Informa, we go to Chris Chang-Yen Phillips to discuss a murder investigation with a forensic entomologist. And after we hear about the physics of fire ants from our partners over at Science Faction.
Piecing together a crime can be a messy business. Police can run up against unreliable witnesses, or destroyed evidence. But what if the animals around a body could tell you a story about what happened? Chris Chang-Yen Phillips has this story from forensic entomologist and Simon Fraser University professor Gail Anderson in Vancouver.

This week’s theme is speciesism! Speciesism refers to the belief that the human species is superior to all other species. Mark Devries is the filmmaker behind “Speciesism: The Movie,” a film that documents the immense scale of pig farms in North Carolina using drone surveillance. Inspired by the animal rights discussion, we’ve included a podcast episode produced by Science Faction that discusses the evolution of land species from fish.
Mark Devries is a filmmaker interested in the ethics of livestock practices used in North Carolina. His documentary, Speciesism: The Movie, shows how large-scale livestock farms raises the issue of animal rights and raises concerns about environmental protection and human health. Tasmia Nishat interviewed Mark Devries about the visual impact of these livestock farms, his ethical concerns, and the methods he used to capture film of private farm property, including using a small plane and drone surveillance.
Science Faction: Fish with Feet
Science Faction is a Canadian miniseries that explains scientific research using 1000 of the most commonly used words. “Fish with Feet” takes listeners on a journey to the lab of Dr. Emily Standen at the University of Ottawa to learn about fish that can walk. They discuss how Dr. Standen’s lab is raising fish out of water and how her work elevates our understanding of the evolution of ancient fish species into land species.
