The Common Descent Podcast

There’s a pandemic on, and we and many of our listeners are spending lots of time at home. On the bright side, it’s a good opportunity to watch movies and record Silver Screen Science! So, we’re putting together some new episodes, to keep you – and ourselves – entertained. This episode, we revisit the King of Monsters: Godzilla (1998) The Common Descent Store is open!

Life ain’t always easy. Injury and disease are a persistent threat for life of all sorts, and that’s been true for as long as there has been life. Fortunately for us, these threats can leave evidence in fossils, teaching us about the lives, struggles, and sometimes deaths of ancient organisms. The study of this evidence is called paleopathology, and in this episode, our friend Laura will explain the ins and outs of the field and share with us some of her favorite examples. In the news: ancient hands, old snakes, the earliest animals, and a new dinosaur.   Time markers: Intro & Announcements: 00:00:00 News: 00:05:00 Main discussion, Part 1: 00:41:00 Main discussion, Part 2: 01:17:00 Patron question: 02:07:00 Check out our blog for bonus info and pictures: http://commondescentpodcast.wordpress.com/ The Common Descent Store is open!

  One of the rewards we offer to our highest-level Patrons is a special mini-episode on an animal or group of their choosing. We’ve done five so far, and we’ve put them together into this compilation so you can all now enjoy them! Special thanks to our Patrons for their generous contributions, and thanks also to our special guests, Keila and the cat. 00:04:15 Desmatosuchus for Julie 00:26:00 Stygimoloch for Danielle 00:45:15 Cryptobranchids for Michael 01:00:00 Parrots for Beth 01:21:00 Graboids for Barbara The Common Descent Store is open!

In 1938, a fishing crew pulled up a fish that everyone thought had been extinct for 70 million years. Since then, coelacanths have become famous not just for their strangely incomplete fossil record, but also for their unique anatomy, their reclusive lifestyle, and their close relationship to land vertebrates. From fossils to genetics, this episode is all about what we know – and what we’re missing – of the story of coelacanths. In the news: an old weasel, fish through time, daily bivalve growth, and cave cockroaches.

Few fossil animals are as popular with the public, as abundant in the fossil record, or as important to the study of past life on Earth as trilobites. These ocean-dwelling arthropods came in an amazing variety of shapes, sizes, and lifestyles, with many thousands of identified species, and they persisted on our planet for more than 270 million years. And best of all, they left behind an incredible fossil record giving us insights into their evolution, life history, and ultimate extinction. In the news: evolution of gliders, a weird worm, tiny marsupial lions, and dino DNA?

Metamorphosis is the process that turns a caterpillar to a butterfly, a fry to a fish, and a tadpole to a frog. Animals have been metamorphosing for over 500 million years, from early crustaceans to the many fish, amphibians, and arthropods that do it today. Larvae, pupae, and adults are known in the fossil record, but the evolutionary history of this incredible life strategy is still mysterious. In the news: a new tyrannosaur, early chameleons, giant turtles, and dinosaur temperatures.

Happy Darwin Day! This time around, we’re talking about Mary Anning! She was one of the earliest modern paleontologists, she helped lay the groundwork for our modern methods of uncovering and understanding fossils, and she was famously underappreciated in her time. We’re joined in our discussion by our friend Brittney Stoneburg from the Western Science Center! Follow Brittney on Twitter and Instagram: @brittandbone And follow our friends at the Western Science Center! In the news: elephant evolution, pterosaur feeding, Jurassic “firewalkers”, and ancient fungi.

The first pterosaur to be scientifically identified was Pterodactylus, more than 200 years ago. Since then, scientists have grappled with understanding these bizarre and fantastic animals, aided by inspired science and incredible discoveries. In this episode, we’ll discuss what we know – and what we don’t know – about how these animals evolved, survived, and ruled the skies in the Age of Reptiles.  In the news: cassowary evolution, the oldest scorpions, sea floor taphonomy, and Neanderthal shells.
