Episode 130 - Sense of Smell

The Common Descent Podcast

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.
