Takahe, merganser, dodgy museum practices and evolution of birds

Associate Professor Nic Rawlence, director of the Otago Palaeogenetics Laboratory, talks to me about the extinct fish eating merganser duck and Takahe research, dodgy museum collecting practices of the 1800’s, how New Zealand has a much more cosmopolitan makeup of biodiversity than previously thought, how the data we have make us form weird relationships that seem implausible, population bottlenecks and more.
