Located in southeastern Alberta is a stretch of gorgeous badlands that are home to some of the world’s absolute best Late Cretaceous fossils. This episode, we explore how Dinosaur Provincial Park earned its designation as a UNESCO World Heritage Site, we list off some of the famous dinosaurs who once lived there, and we discuss a fraction of the many fossil discoveries that have been made at the Park since the late 1800s.

Welcome ... to Spookulative Evolution.

Spook-E Season is back! All throughout October, we pick monsters from myth and media and speculate 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 Monsters of Nintendo!

This episode, we take a trip to the Kingdom of Hyrule. How might nature develop an octopus-like monster with a penchant for projectiles? Our creatures to create this time: Ocotoroks.

The faces of vertebrate animals are often soft and full of teeth, but there is a common alternative. Birds, turtles, and many more groups have developed toothless snouts covered in a tough sheath. This episode, we’ll explore the defining features of beaks and their various functions. And we’ll take a tour through animal life past and present to investigate the reasons behind the repeated evolution of beaks among dinosaurs and beyond.

In the news: Life on Mars, ancient sharks, mammoth microbes, and ant-eaters.

Dodos are probably the single most famous case of recent human-induced extinction. First documented in the late 1500s and extinct within a century, dodos have become a global reminder of the devastating potential of human activity. This episode, we review the brief history of human interactions with dodos, and we explore what recent research and fossil evidence has taught us about these birds and their closest relatives.

In the news: Cretaceous crocs, extra-spiky dinosaurs, turtles of the sea, and cave fish evolution.

Forests are among the most widespread and diverse biomes on our planet. This episode, we’re joined by our favorite paleobotanist, Dr. Aly Baumgartner, to explore what defines a forest, how these habitats function, and how they differ around the globe. Then, we’ll take a trip into the past to discuss how paleontologists study ancient forests and how these biomes have changed over hundreds of millions of years.

In the news: ocean sediments, early penguins, island foxes, Canadian dragonflies, and ancient deer.

Most vertebrate animals on land get around on all fours, but some of us have committed to two-legged locomotion. This episode, we explore the various ways animals have evolved bipedalism and the many benefits that come with it. We’ll also take a look at how we identify bipedal animals in the fossil record, and we’ll zoom in on the evolutionary story behind Earth history’s most successful bipeds.

In the news: potato origins, trilobite legs, bone worm burrows, and australopithecine sexes.

Mutation. It is the key to our evolution. As our cells constantly divide and reproduce and replicate our DNA, errors and inconsistencies develop, leading to the incredible variation of life that drives evolutionary change. This episode, we explore the genetic mechanisms behind mutation and we discuss how scientists study mutations to understand the evolutionary history of life on Earth.

In the news: Neanderthal tools, caiman food, dancing dinosaurs, and ancient integument.
