Episode 61 - Behavior in the Fossil Record

Episode 61 - Behavior in the Fossil Record

May 18, 2019

It’s easy to see how fossils can teach us what ancient animals looked like, or how they evolved. But what about the ways they moved, ate, socialized, reproduced? In this episode, we explore the innovative ways paleontologists have devised to interpret the behavior of ancient animals. From their bones, their tracks, their living relatives, and modern clever experimentation, we can come to understand more than you’d ever imagine about behavior in the fossil record.

In the news: a Denisovan jaw, a new bat-winged dinosaur, a cave of wonders, and a flapping robot.

Episode 60 - Turtles

Episode 60 - Turtles

May 4, 2019

Turtles are so weird and wonderful. They're unlike any other living reptiles, mostly because they've turned their entire torso skeleton into an armor-home. A glimpse into the fossil record reveals that they've been this way for more than 200 million years. And yet, with all our data on living and extinct turtles, they remain one of the most mysterious and confusing living vertebrate groups. Here's an episode about all of that.

In the news: death rolls, one huge predator, one weird crab, the Gray Site rhino, and a poop snake.

Episode 59 - Bats

Episode 59 - Bats

April 20, 2019

Many groups of life have conquered the land and water, but only four times in evolutionary history has life taken to the air. The most recent group to achieve flight are bats. Their combination of flight and advanced echolocation have earned them an incredible diversity, a worldwide distribution, and a deep-seated place in human culture, but their evolutionary history is a long-standing mystery, and their fossil record is nearly non-existent. But that's not going to stop us from geeking out about them!

In the news: dinosaur scales, diverging crows, a new human, seal evolution, and that butchered mastodon again!

Episode 58 - The Bone Wars

Episode 58 - The Bone Wars

April 6, 2019

It was the late 1800s, and paleontology was just getting started in the Americas. Two prolific and passionate scientists, Edward Drinker Cope and Othniel Charles Marsh, among the earliest prominent fossil researchers on the continent, struck up a legendary rivalry. Their battles took place in the field and in the literature, and over three decades they engaged in some of the nastiest and most petulant quarreling in scientific history. This infamous era in early paleontology became known as The Bone Wars.

In the news: an egg in an ancient bird, a new mastodon, a giant T. rex, and the day the Cretaceous ended.

Episode 57 - Evolution of Flowering Plants (Angiosperms)

Episode 57 - Evolution of Flowering Plants (Angiosperms)

March 23, 2019

Look who's back - our favorite paleobotanist, Aly Baumgartner!

And that means it’s time for more plants! As you may have noticed, the world around you is absolutely full of flowers. Angiosperms have dominated nearly every terrestrial ecosystem on the planet, but the story of their early evolution is a famous conundrum. Darwin called it an “abominable mystery,” but there are some tantalizing clues as to how this group of plants got their start and then evolved to the incredible diversity we see today.

In the news: new Cayman mammals, louse camouflage, a geologic orrery, and language evolution.

Episode 56 – The Evolution of Evolutionary Theory

Episode 56 – The Evolution of Evolutionary Theory

March 9, 2019

One of the main themes of this podcast is the evolutionary history of life. This concept is familiar to all of us today, but our current understanding of evolution is the culmination of a very long history of scientific inquiry. In this episode, we’ll introduce you to some of the biggest names in this story, from Aristotle to Darwin, as we explore the evolution of evolutionary theory.

In the news: tiny frogs, an ancient nesting ground, algae evolution, and a tusked sea cow.

Episode 55 - The “Sixth Extinction” (Modern Biodiversity Crisis)

Episode 55 - The “Sixth Extinction” (Modern Biodiversity Crisis)

February 23, 2019

Usually, when we talk about mass extinction, we’re referring to events long past. But scary levels of extinction are a fact of our current world, as well. So much so that current events have been labeled the "Sixth Extinction.” In this episode, we discuss just how bad our current ecological crisis is, what’s causing it, and whether or not it truly deserves to be called a mass extinction. We also discuss what’s already being done – and what we can all do – to counteract catastrophe. It’s a depressing one, folks, but all isn’t lost. Stay informed and stay hopeful!

In the news: a new island, ancient turtle cancer, megalodon extinction, and that one Archaeopteryx feather.

Episode 54 - Alfred Russell Wallace

Episode 54 - Alfred Russell Wallace

February 9, 2019

Happy Darwin Day! Last year around this time, we were joined by Dr. Sarah Bray to discuss the life and times of Charles Darwin. This time, Sarah joins us again to discuss his colleague and natural selection co-discoverer, Alfred Russell Wallace. In 1858, the year before Darwin published his famous book, he received a letter from a young, adventurous, sometimes tragic man in the throes of illness in southeast Asia. To Darwin’s shock, the letter included precisely the same biological insights he had been working on. That letter came from Alfred Russell Wallace.

Find Sarah and her colleagues on the podcast Discovering Darwin! http://discoveringdarwin.blogspot.com/

In the news: fast-evolving mice, a small-headed reptile, an early Antarctic archosaur, and really old amoebae.

Episode 53 - The Baculum (Penis Bone)

Episode 53 - The Baculum (Penis Bone)

January 26, 2019

It's been called the most diverse of all bones. It comes in an incredible variety of shapes and sizes, living and fossil, scattered across the mammalian family tree. It's called the baculum, the os penis, and in this episode we discuss what it does, who has it, what it means for paleontologists, and the evolutionary processes that made it what it is today.

In the news: whales eating whales, pregnant plesiosaurs, robo-tetrapods, and the first American dogs.
