![Episode 131 - Volcanoes]()
January 22, 2022
Volcanoes are fascinating, devastating, and fundamental to Earth systems. Volcanic eruptions can transform ecosystems, landscapes, and even the atmosphere, and at their most extreme, the effects of volcanism can be global and long-lasting. In this overstuffed episode, we discuss the many forms and features of volcanic activity, and we take a look at the complex and dramatic interaction between volcanoes and life on Earth.
In the news: ankylosaur brains, an Australian rainforest, donkey hybrids, and the Tonga volcanic eruption.

![Episode 130 - Sense of Smell]()
January 8, 2022
With every breath you take, you’re collecting information about your surroundings. We humans are actually pretty skilled smellers, as these things go, but olfactory abilities vary widely across the animal kingdom (and beyond). In this episode, we discuss how smelling works, what smelling is good for, and how scientists explore the evolutionary history of smell.
In the news: giant ichthyosaurs, giant millipedes, long-tongued birds, and oviraptorid embryos.

![Episode 129 - Rhinos]()
December 25, 2021
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.
In the news: ancient croc hunting, dinosaur colors, shrinking orangutans, and ammonite soft tissue.

![Episode 128 - The Deep Sea]()
December 11, 2021
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.
In the news: blade-tailed ankylosaurs, ostrich-like dinosaurs, shrimps in clams, and carnivorous ichthyosaurs.

![Episode 127 - The Hell Creek Formation]()
November 27, 2021
Located across a wide area of the Upper Great Plains of the United States, the Hell Creek Formation is one of the world’s premier locations for studying the Age of Dinosaurs, especially trends of evolution – and extinction – at the very end of the Mesozoic Era. In this episode, we discuss the ancient history and scientific history of the region, including some famous finds and groundbreaking research.
In the news: giant ammonites, extinction beetles, baby pterosaurs, and the controversial Tetrapodophis.

![Episode 126 - Mimicry]()
November 13, 2021
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.
In the news: Cambrian bryozoans, early tusks, hermit worms, and parthenogenetic condors.

![Spook-E - Triffids]()
October 30, 2021
Welcome ... to Spookulative Evolution.
October is here, and that means it’s time for Spook-E! Each episode throughout this month, we’re choosing a famous monster and discussing how it – or something like it – might evolve under the rules of evolution and natural selection, pulling inspiration from organisms of the real world. This year’s theme: monster plants.
This episode, we face a more modern monster, star of page and screen. Can we invoke natural processes to develop a plant that haunts humans and strikes with a deadly lash? Our creatures to create this time: triffids.
