Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us. In this episode, Jaakko Pohjoisma\u0308ki, Jukka Jernvall, and Ari Lo\u0308ytynoja discuss the evolutionary history of the Saimaa ringed seal. In this episode, we cover: \u2022[00:00] Introduction \u2022[01:06] Molecular biologist Jaakko Pohjoisma\u0308ki introduces Lake Saimaa and the Saimaa ringed seal. \u2022[02:30] Zoologist Jukka Jernvall talks about the characteristics of species isolated by glaciation. \u2022[03:27] Evolutionary biologist and bioinformatician Ari Lo\u0308ytynoja explains the genetic and demographic methods of the study. \u2022[04:11] Lo\u0308ytynoja and Jernvall explain why the results were surprising and where the study turned next. \u2022[06:20] Pohjoisma\u0308ki and Lo\u0308ytynoja describe the study\u2019s implications for biodiversity in postglacial habitats. \u2022[07:50] Jernvall and Lo\u0308ytynoja talk about the study\u2019s caveats and limitations. \u2022[10:14] Conclusion.
