Episode 129 - Rhinos
26 december 2021 · 2 uur 22 min
Today, rhinos are famous for their large size and impressive horns (and their distressing conservation status, sadly), but modern rhinos are only a small sample of what rhinos have been over time. Thanks to a surprisingly good rhino fossil record, we have a pretty good picture of how these animals got started and of the surprising forms they’ve taken since, from horse-like runners to hippo-shaped waders to gargantuan behemoths. This episode, we discuss rhinos as we know them, rhinos when they were weird, and a few rhino-y things that aren’t rhinos at all. Lees meer
In the news: ancient croc hunting, dinosaur colors, shrinking orangutans, and ammonite soft tissue.

Episode 128 - The Deep Sea
12 december 2021 · 2 uur 11 min
Far below the ocean surface is a vast environment of cold, darkness, very scarce food, and surprisingly diverse life. Deep sea life is quite mysterious, in part because of their unusual adaptations for surviving in such tough habitats, and also because it’s very difficult to study organisms of the deep, modern or fossil. In this episode, we discuss what is known about the adaptations, evolutionary history, and diversity of life in the deep sea. Lees meer

Episode 126 - Mimicry
14 november 2021 · 2 uur 6 min
Evolution loves to plagiarize. You might be surprised at just how useful it can be for an organism to copy the signals, sights, sounds, and smells of others. Mimicry is all about making use of miscommunication. In this episode we’ll discuss the astounding diversity of modern mimics, the rare examples of fossil mimics, and the complex and confusing evolution patterns of mimicry. Lees meer

Episode 124 - Snowball Earth
17 oktober 2021 · 2 uur
An Earth covered in ice might sound far-fetched, but there’s reason to think it has actually happened in the past – more than once. In this episode, we examine the Snowball Earth hypothesis and the geologic evidence and climate models that back it up, as well as some of the major lingering questions: Just how snowy is the snowball? How could this start? How could it end? And how did life fare on a frozen planet? Lees meer

Episode 122 - Plate Tectonics
19 september 2021 · 2 uur 7 min
The Earth is in motion beneath our feet. The shifting and grinding of the tectonic plates is responsible for the shape of our planet’s surface and – directly or indirectly – nearly all the activity that happens upon it. Plate tectonics has a deep and fascinating history, both as a force that has shaped the Earth for billions of years and as a surprisingly recent foundational scientific theory. Lees meer

Episode 121 - Brains
5 september 2021 · 2 uur 10 min
Nearly all animals have some form of nervous system, and this system is often monitored and regulated by a brain. We humans are particularly proud of our enormous brains, but these organs come in all shapes and sizes across the animal kingdom, past and present. In this episode, we discuss brain diversity, the sometimes roundabout ways we explore brains in the fossil record, and what we’ve come to learn about the evolution of brains. Lees meer

Episode 119 - India
8 augustus 2021 · 1 uur 44 min
India is a landmass with an incredible history. Over the past half-billion years, it has spent time with the southern continents, time as an island-on-the-move, and time with the northern continents. Its fossil record is a combination of southern life, northern life, and uniquely Indian life, and its geologic history is not only the story of a traveling subcontinent, but also the origin story of one of Earth’s most impressive mountain ranges.

Episode 118 - Trace Fossils
25 juli 2021 · 2 uur 4 min
As organisms live, grow, and move in their environments, they leave all sorts of traces in their surroundings, and these can become fossilized just like body parts can. Trace fossils (ichnofossils) can include evidence of burrowing, walking, feeding, and more. Individual trace fossils are great for understanding the behaviors of ancient organisms, and communities of trace fossils can help us track major changes in ecosystems through time. Lees meer

Episode 117 - Crabs and Carcinization
11 juli 2021 · 1 uur 56 min
What exactly is a “crab” anyway? One answer is that they are among the most diverse and successful living arthropods. Another answer: they are many different groups of crustaceans that have converged on a crabby body plan. In this episode, we discuss the diversity and evolution of “true crabs,” the incredible phenomenon of carcinization that keeps creating crabs, and what it really means to be a “crab.” Lees meer

Episode 116 - Ichthyosaurs
27 juni 2021 · 2 uur 11 min
The history of evolution has seen many land animals move to the sea, but few have done it with such success and specialization as ichthyosaurs. These Mesozoic marine reptiles were the first group of tetrapods to truly dominate the marine realm, and they evolved some of the most extreme adaptations – and largest bodies – of any ocean-dwelling tetrapods. This episode, we discuss how they got started, what they did, where they went, and why they’re so incredibly famous. Lees meer

Episode 115 - Biomes
13 juni 2021 · 1 uur 53 min
All over the Earth, there are biological communities that differ depending on the local climate and landscape. These are biomes, and biologists love to map them to unravel patterns of ecosystem distribution. But biomes also change over time as climates and landscapes shift. In this episode, our favorite paleobotanist, Dr. Aly Baumgartner, joins us to discuss how we identify biomes in the past and present, how they’ve changed over time, and what it means for a new biome to arise … or for an old one to go extinct.

The geologic record of Earth is an archive of data on the causes and effects of changing climates. As climate changes, it impacts everything from plants and animals to rocks and rivers. The study of ancient climates is paleoclimatology, and it’s important not only for our understanding of climate in the past, but also for teasing out what’s happening with our climate today and what we can expect for the future.

Episode 111 - Eusociality
18 april 2021 · 2 uur 10 min
There isn’t much on Earth quite like an ant colony or a beehive. Lots of animals are social, but relatively few are eusocial. It’s a bizarre lifestyle, living in large multi-generational colonies with lots of members who don’t reproduce but instead dedicate their lives to protecting and nourishing the offspring of the few reproducers. In this episode, we discuss the many questions surrounding this phenomenon, including how many times this trait has evolved, why it’s apparently so beneficial, and exactly how natural selection could even produce such a strange lifestyle.

Episode 104 - Pinnipeds
10 januari 2021 · 1 uur 42 min
Seals, sea lions, and walruses (oh my!) are widespread, successful, and invariably charming. In this episode, we take a look at how they’re adapted for their aquatic lifestyles and how they might have gotten that way. We’ll explore some of the unanswered questions about their origins and evolution, and we’ll take a tour through their diverse but spotty fossil record. Lees meer

Episode 103 – The Paleocene-Eocene Thermal Maximum
27 december 2020 · 1 uur 45 min
The PETM has been called the largest natural climate change event of the Cenozoic Era. It marks the transition from the ecosystems of the Paleocene to the more familiar world of the Eocene and is thus an important step in making the world the way we know it today. But maybe most importantly, it is a dramatic case study in what happens when a huge amount of Carbon injected into the atmosphere triggers rapid warming of global climate … you know, in case anyone needs to know about that.

Episode 102 - Parasites
13 december 2020 · 2 uur 3 min
The word parasite doesn’t typically invoke a lot of happy thoughts for us humans, but as far as life on Earth is concerned, parasitism is a path to success. As we discuss in this episode, an incredible diversity of organisms, past and present, have developed an equally incredible diversity of strategies for stealing, siphoning, and exploiting resources from other organisms.

29 november 2020 · 1 uur 53 min
Is there a group of dinosaurs more iconic than sauropods? Famous for their ridiculously long necks, their global success, their astounding diversity, and of course for their unparalleled size, sauropods have fascinated and puzzled people for centuries. In this episode, we’ll explore what makes sauropods and their ancestors special, and we’ll talk a bit about how they functioned at truly colossal scales. Lees meer

Episode 100 - The Origin of Life
15 november 2020 · 2 uur 40 min
One hundred episodes is kind of a big deal, so we figured we’d pick a big deal kind of topic, and it doesn’t get much bigger than this. Lees meer
As far as we can tell, all life on Earth is descended from a common ancestry – at some point, at least once, life originated on Earth. But when, where, and how? These are open questions that have been subject to lots of scientific and philosophical discussions and experiments. In this episode, we’ll touch on some of the biggest questions: What even is life? How old is life on Earth? What steps led to the first living things? Is Earth the only place this has happened?
In the news: dino bone disease, amphibian chameleons, ancient social mammals, and pterosaur diets.

Insects must be among the most impressive animals in Earth history. For hundreds of millions of years, they have been some of the most significant animals on land in terms of their abundance, diversity, and ecological impact. Their deep story is marked by evolutionary innovations that weren’t just major events for insects, but major events for the entire planet. This episode, we barely scratch the surface of the insect story. Lees meer

Episode 98 - Species and Speciation
18 oktober 2020 · 2 uur 3 min
When we study life, past or present, we talk a lot about species, their evolution, their diversity, their extinction, and more. But we don’t often slow down to discuss what we really mean by that. What is a species? How and where do new species arise? It turns out this topic is much more complicated – and controversial! – than it may seem. In this episode, we’ll touch on the basics and discuss why scientists get so worked up about species and speciation. Lees meer

Episode 97 - Venom and Poison
4 oktober 2020 · 1 uur 55 min
Okay, that’s not a great title. More accurately, we’re discussing toxins, the substances that organisms produce for chemical defense or attack against each other. Toxins are found in practically all living things, they function as part of immune systems, poisonous defenses, and predatory venom, and they have all sorts of amazing effects from discomfort to death. In this episode, we’ll touch on who has them, what they do, and what we know about the long, complex evolutionary history of venom and biological poison. Lees meer

Episode 95 – The Carboniferous Rainforest Collapse
6 september 2020 · 2 uur 4 min
This episode marks the end of our extinction series, but on the bright side, Aly’s here! Lees meer
Most of the extinction events we discuss are very animal-focused, but the end of the Carboniferous Period featured one of history’s worst plant extinctions. This event wiped out the famous ecosystems of the Carboniferous, reshuffled ecosystems, and ushered in a more familiar world of plants. In this episode, as usual, we discuss what happened, why, and how it impacted the world.
In the news: a croc-bitten sloth, a dinosaur embryo, dinosaur dimorphism, and ancient hibernation.
