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, Quentin Martinez describes a reconstruction of olfactory capabilities in extinct mammals. In this episode, we cover: \u2022[00:00] Introduction \u2022[01:14] Evolutionary biologist Quentin Martinez tell why we want to reconstruct olfaction in extinct animals. \u2022[02:35] He introduces the olfactory bulb endocast, or space within the skull that contained the olfactory bulb, and explains why it\u2019s important in evaluating olfaction in extinct animals. \u2022[04:24] Martinez talks about studying the genomics of chemoreceptor genes, in addition to the bony structure of the olfactory bulb endocast. \u2022[05:23] He tells about the results of the study. \u2022[07:46] Martinez lists possible insights from reconstructing extinct animals\u2019 olfaction. \u2022[08:53] He lists the caveats and limitations of the study. \u2022[10:16] Conclusion.
