The Fish-Tetrapod Transition (Summer Repeat)
Podcast: In Our TimePublished On: Thu Sep 12 2024
Description: Melvyn Bragg and guests discuss one of the greatest changes in the history of life on Earth. Around 400 million years ago some of our ancestors, the fish, started to become a little more like humans. At the swampy margins between land and water, some fish were turning their fins into limbs, their swim bladders into lungs and developed necks and eventually they became tetrapods, the group to which we and all animals with backbones and limbs belong. After millions of years of this transition, these tetrapod descendants of fish were now ready to leave the water for a new life of walking on land, and with that came an explosion in the diversity of life on Earth.WithEmily Rayfield Professor of Palaeobiology at the University of BristolMichael Coates Chair and Professor of Organismal Biology and Anatomy at the University of ChicagoAndSteve Brusatte Professor of Palaeontology and Evolution at the University of EdinburghProducer: Simon TillotsonIn Our Time is a BBC Studios Audio Production
