Episode 46: Understanding Biodiversity

The world is currently undergoing a massive biodiversity crisis, and many people have said that we are in the next major mass extinction event, with species going extinct each day. Unfortunately, we don't currently understand what aspects control biodiversity, and how the past can help us understand the present and the future.

Associate Professor Lindsey Leighton of the University of Alberta discusses his work combining research of modern invertebrate marine fauna related to biodiversity and ecosystems with studies of the fossil record in order to further understand this problem.
