Episode 181 - Dragonflies

The Common Descent Podcast ·

2023/12/24

Dragonflies and damselflies are incredible insects. They are arguably the world’s most skilled fliers, arguably the world’s most successful predators, and arguably the best insects (so says David). Not only that, they and their ancient cousins have been abundant and successful aerial predators for over 300 million years. This episode, we discuss what sets these bugs apart from all the rest, we explore what’s known of their evolution from their surprisingly good fossil record, and of course we

Episode 180 - Filter Feeding

The Common Descent Podcast ·

2023/12/10

Filter feeding is among the most widespread dietary strategies in the world. From tiny bivalves to massive basking sharks, animals have developed a vast array of convergent strategies for filtering tiny food particles out of the water. This episode, we discuss what it takes to be a filter feeder, why it’s so common, the various methods animals employ to make it happen, and how we try (sometimes successfully) to identify filter feeding in the fossil record. In the news: Thailand trilobites, mammal

Episode 179 - Thermoregulation

The Common Descent Podcast ·

2023/11/26

If things get too hot or too cold, the crucial processes inside the cells and tissues of living organisms stop working properly, and that’s bad. So, organisms expend a lot of time and energy managing their body temperatures. This episode, we break down the familiar concepts of “warm-blooded” and “cold-blooded,” we discuss the many adaptations that animals use to manage the heat, we explore what evidence allows us to interpret thermoregulatory strategies in the fossil record, and we investigate what

Episode 178 - Ears

The Common Descent Podcast ·

2023/11/12

Listen up! The world around us is full of sound, and animals have evolved numerous strategies for receiving and interpreting those sounds. In this episode, we discuss the many varieties of sound-sensing organs and how they’ve evolved repeatedly throughout life history. We’ll also explore some of the other important things that ears can do, including the ever-important task of maintaining our equilibrium. In the news: carnivorous lampreys, caterpillar legs, early dragonflies, and the sea star body

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 - might evolve under the rules of evolution and natural selection, pulling inspiration from organisms of the real world. This year’s theme: Dragons. This episode, we snuggle up with the sweeter side of dragons. How might natural processes produce

Episode 177 - Neanderthals

2023/10/29

These days, we Homo sapiens are the only humans around, but that wasn’t always the case. This episode, we are joined by special guest Dr. Bridget Alex to discuss our most famous extinct cousins, Neanderthals. We explore what makes them similar and dissimilar to us, what evidence we use to study their lives and culture, and how our understanding of them has grown from outdated misrepresentations to the complex and fascinating people we now know them to have been. In the news: a fossil bat skull,

Hadrosaurs (the so-called “duckbill” dinosaurs) and their fellow ornithopods were among the most abundant and successful dinosaur groups of all time. This episode, we discuss their evolution and diversity, and we explore some of the most outstanding and unique features of the group, including their incredible fossil record, complex social behaviors, wacky head ornaments, and their truly incredible mouths.

Episode 175 - Plant Defenses

The Common Descent Podcast ·

2023/10/01

Plants are delicious, nutritious, and full of energy, so they’re prime targets for all sorts of herbivores, parasites, and pathogens. But plants aren’t just sitting passively accepting attacks, they use a variety of strategies to defend themselves, from the frustrating to the fatal. This episode, we’re joined by our favorite paleobotanist, Aly Baumgartner, to discuss the many ways plants defend themselves – physically, chemically, and beyond – and the fascinating evolutionary history of plant

Episode 174 - The Mesozoic Marine Revolution

The Common Descent Podcast ·

2023/09/17

Earth’s oceans change over time, not just in their size and shape, but also in the very dynamics of their ecosystems. The stage was set for modern ocean ecosystems by an event called the Mesozoic Marine Revolution, a dramatic restructuring of ecology in shallow seas that saw the rise of many forms of active predatory lifestyles. This episode, we discuss the fossil evidence, the major players, and the ongoing and sometimes contentious research into this crucial period. In the news: early arthropods,

This episode, we discuss the adaptations animals use to get around the challenges of plant-eating, as well as the incredible history of the repeated origins of herbivory.

Episode 172 - Toothed Whales

The Common Descent Podcast ·

2023/08/20

For much of their evolutionary history, whales have been divided into two main lineages: baleen whales and toothed whales. The toothed variety are especially diverse today, including sperm whales, belugas, porpoises, and so, so many dolphins (among others). This episode, we explore what makes toothed whales distinct – besides the obvious – and what the whale fossil record tells us about how they came to be among the most successful marine animals in Earth history.

Episode 171 - The Tethys Sea

2023/08/06

Throughout Earth history, tectonic forces have changed the shape of the continents – and the oceans! You might be familiar with the Tethys Sea as an ancient ocean nestled against Pangaea, home to marine reptiles and more, but there’s actually a whole series of ancient bodies of water that bear this name. In this episode, we explore the various iterations of the Tethys, discuss how geologists study them, and examine how these ancient oceans shaped the world as we know it today. In the news: crocodile

Mammals are famous for their ability to produce milk, a special substance that is essential for providing newborns with the ingredients they need for healthy development. As it turns out, mammals aren’t the only ones. Milk-like substances have evolved in many groups of animals which nourish their developing young.
