Lampreys may be jawless fish, but their fossils have a lot to say about long-held assumptions concerning evolution. On this episode, McLain, an assistant professor of biology and geology at TMU, discusses a recent article entitled “Fossil lamprey larvae from South Africa overturn assumptions about vertebrate origins.” The article was written by Robert W. Gess, a paleontologist who worked with Tetsuto Miyashita, Kristen Tietjen and Michael Coates to publish a paper in “Nature” highlighting their findings.
