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