Communication is key among organisms. Various signals – sights, sounds, smells – can serve to warn, attract, or manipulate others. So it’s no surprise that many organisms have evolved to copy the signals of others for their own deceitful purposes. In this episode, we discuss the diversity and evolution of Mimicry.

Far to the north and far to the south, conditions on Earth get weird. Cold climates and periods of perpetual night or day create some of the most unique habitats on the planet, and yet life has thrived there throughout Earth history and continues to do so today. This episode, we discuss the diversity, history, and adaptations of Polar Life.

Subterranean passages and chambers within the crust of the Earth form unique environments, often carved out over thousands of years, which create homes for rare and bizarre groups of organisms and provide valuable fossil resources. This episode, we discuss the geology, biology, and paleontology of Caves.

There isn’t much on Earth like an ant colony or a beehive. It’s a bizarre lifestyle, creating multi-generational groups where most members don’t reproduce but protect the offspring of others. This episode, we discuss the questions surrounding the details and evolution of Eusociality.

Most plants are content to sit still and take in sunlight and soil nutrients, but when conditions are tough, some plants get hungry! The habit of devouring animal prey has evolved in plants numerous times. In this episode, we discuss the varied strategies and evolutionary history of Carnivorous Plants.

All animals change as they get older. Typically these changes are slow and subtle, but many animals famously undergo sudden and dramatic changes from young to adult – caterpillars to butterflies; fry to fish; or tadpoles to frogs. In this episode, we discuss the diversity and history of the incredible phenomenon called Metamorphosis.

Sex adds a whole other level of complexity to the lives of organisms. On top of the struggle to survive fueling natural selection, they must also compete to find a mate and reproduce. In this episode, we discuss one of the more bizarre mechanisms driving evolution: Sexual Selection.

Ancient animals didn’t just stand around. They moved, interacted, hunted, reproduced, and did all the things animals do. It’s easy to image all of that information is lost to time, but there are all sorts of ways paleontologists can find those clues. In this episode, we’re exploring the tools, techniques, and amazing fossil finds that help us understand Behavior in the Fossil Record.

The sounds that animals make are a huge part of their behavior and how we recognize them. The sounds that prehistoric animals made, on the other hand, are lost to the past. But perhaps not entirely. There have been a few instances where fossils have given us clues to the noises these animals may have made, allowing paleontologists to reconstruct the Sounds of the Past.
