The Common Descent Podcast

Evolution just loves a nice pair of oversized canines, especially on mammalian predators. Saber-toothed animals have shown up over and over again – we even have some today – but despite their similarities, not all of these toothy species were using their canines the same way. This episode, we explore the various shapes of functions of saber teeth and the disparate lineages that have sported them.

In the news: The Fossil Keeper’s Treasure, the size of megalodon, and vulture feathers.

Leave a carcass or a log or a pile of poop out in the wild long enough and it will break down into its component parts. Decomposers are an often-overlooked but essential component of ecosystems past and present. This episode, we explore the varied processes of decomposition and how scientists study decomposers and use that information. We’ll also discuss the importance of decomposition to the fossil record, as well as how we can identify signs of decomposers from the distant past.

In the news: temnospondyl extinction, hot crocs, foraging birds, narwhal tusks, and giant flying squirrels.

When vertebrates first moved onto land, they gave rise to a variety of amphibious tetrapods. The most diverse and successful of these were temnospondyls, which were some of the most important species in early land and freshwater environments. This episode, we’ll explore temnospondyls’ evolutionary history, their ecological variety, and their mysterious connection to modern amphibians.

In the news: domesticating dogs, early birds, color evolution, and changing seeds.

E. D. Cope is one of the most recognizable and notorious names in paleontology history. He did some of the most important early work in vertebrate paleontology, he was one half of the dueling duo in the infamous Bone Wars, he named some of the most famous fossil animals, and he was profoundly irresponsible and unethical with his science. This episode, we’re joined by Astrid Lundberg to explore the life and legacy of Edward Cope, investigating such questions as: How did he get his start? What lasting contributions did he make to paleontology? And what was wrong with this guy?

In the news: giant small pterosaurs, plesiosaur skin, bat teeth, and African isotopes.

The evolution of mineralized tissues is responsible not only for the incredible success and diversity of vertebrate animals, but also for their extraordinarily informative fossil record. This episode, we explore the detailed anatomy of bones and their deep evolutionary history, we touch on some of the ways they’re important for paleontology, and we take some time to discuss the secrets that can be found inside of ancient bones.

In the news: croc vs pterosaur, hominin diets, ears and gills, and reptile food.

You might know them as ghost sharks, rat fish, or spook fish. Chimaeras are close cousins of sharks and rays, equipped with distinctive and unusual features in their fins, teeth, and reproductive structures. In today’s oceans, chimaeras are rare and easy to miss, but their extended family includes some of the most diverse and iconic fish of the Paleozoic seas. In this episode, we’ll explore the traits that set chimaeras apart, we’ll take a tour through their ancient relatives, and we’ll investigate what their most famous cousins were doing with their strange spiral rows of teeth.

In the news: Baltic herrings, Cambrian arms race, pterosaur tails, and early dinosaurs.

Most theropod dinosaurs are sleek predators built for speedy movement and efficient hunting. Therizinosaurs are unusual. They’re slow and stocky and, in many ways, more like the famous plant-eating dinosaurs. This episode, we’ll explore the diversity of therizinosaurs, the winding path that paleontologists took to understand them, the many ways they became specialized for a diet of plants, and what was going on with those claws.

In the news: Parasaurolophus crests, Scottish bears, anglerfish evolution, and Clovis diets.

Evolution involves the innovation of new features, but even more reduction of old features. Those reduced features might disappear, develop in a new direction, or just linger as a functionless evidence of deep ancestry. This episode, we explore how we identify vestigial traits, how they help us understand evolutionary history, and the various evolutionary paths vestigial structures can take.

In the news: giant worm lizards, drumstick evolution, dinosaur poop, and pterosaur transitions.

Welcome … to Cute-E!

Every October during Spook-E, we have fun speculatively evolving monsters from myths and stories, but we leave out the cuddlier side of fiction. In Cute-E, we’re choosing kinder creatures and discussing how they – or something like them - could evolve here on Earth, pulling inspiration from real-world species across our planet’s history. This year’s theme is Tiny Monsters.

This episode, we look at a local legend. How might real-world evolution result in elusive and mysterious rabbits with antlers? Our creatures to create this time: Jackalopes.

It’s the final part of our fungal trilogy!

Fungi and animals interact in a wide variety of ways, from parasitism to partnership to predation. This episode, we explore how fungi and animals have evolved alongside each other and the adaptations they have developed to take advantage of each other, and we’ll examine how far back we can find these fungus-animal interactions in the fossil record.

In the news: pterosaur feet, sauropod tails, a Cretaceous crater, and fossil fireflies.

Our fungal celebration continues!

The relationship between fungi and plants is one of the most famous and consequential connections in biological history. This episode, Aly is here to help us explore how fungi and plants work together and work against each other, what we know about the deep history of their relationship, and how fungi and plants together have shaped the world as we know it.

Fungi will return…

In the news: toothy birds, polar forests, coelacanth evolution, and a Pennsylvanian lagerstatte.

Some animals are specialists at eating particularly tough foods like shells, seeds, and bones. Adaptations for a durophagous diet come in many forms in almost all major groups of life. This episode, we discuss how so many animals tackle tough foods, what behaviors and anatomy help them to do it, and the importance of durophagy for understanding fossils and the history of Earth ecosystems.

Leaves. They’re everywhere. They’re the main photosynthesizing organs of plants, and they’re the main source of green on our green-and-blue planet. Leaves come in a truly dizzying variety of shapes, sizes, and specialized functions, and their early evolution laid the foundation for terrestrial ecosystems as we know them. This episode, Aly joins us yet again to talk about the anatomy and diversity of leaves and the incredible information we can learn from leaves in the fossil record.

In the news: croc cousins, horned dinosaurs, dinosaur myths, and fish brains.

Terrestrial animals get around using a variety of gaits: walking, running, galloping, etc. Some of these gaits are particularly bouncy! Hopping comes in many forms in many different groups of animals. This episode, we’ll discuss what makes a particular gait “hoppy,” what functions hopping serves, and what adaptations are found in the best hoppers. Then, we’ll explore what we can tell about hopping in the fossil record.

An animal eating another member of its own species might sound like a rare and abnormal occurrence – and it is often portrayed that way – but cannibalism is actually extremely widespread and common in nature. Some animals are occasional cannibals, while some go so far as to rely on this behavior to fuel proper growth and development. In this episode, we’ll discuss some of the varieties of cannibalism, explore how this behavior has been misunderstood and misconstrued in the past, and investigate some evidence from the fossil record.

In the news: toothless Cretaceous birds, giant river dolphins, Alaska dinosaurs, and Kermit the temnospondyl.

Among the most spectacular of animal behaviors is migration, the habit of many species to undertake massive journeys, sometimes traveling thousands of kilometers to access food or breeding grounds. This episode, we explore the incredible diversity of migratory behaviors, we examine the functions and adaptations that make migration happen, we discuss how migration is defined, and we investigate some of the tools we can use to identify migration in the distant past.

In the news: giant crabs, fossil forests, early cephalopods, and mating termites.
