Narwhals are whales, and super cool ones at that. But that cool thing coming out of their heads is a tusk, not a horn. Which means it’s a tooth! And it’s the only known spiral tooth to boot! In this episode, we learn all about narwhals (what that tusk is for and how they’re connected to the myth of the unicorn) and the evolution of teeth (from scale-like nubbins to the versatile chompers we have today). Plus our Moment of Um explores whether or not water has a taste. Today’s episode is sponsored by KiwiCo (kiwico.com/brainson), Khan Academy Kids (khan.co/freekidsapp) and iD Tech (idtech.com/brains).

You might think flavor is what happens on your tongue – and it is. But it’s also so much more. Flavor is influenced by all the senses. How food looks, smells and feels can make a difference. Even the sounds you hear while eating can impact how you perceive taste. We’ll visit a tastebud beauty salon, talk with a chef researcher and do some experiments provided by our friends at America’s Test Kitchen Kids. Plus: a three-part Mystery Sound and a Moment of Um that answers the question: “What makes spicy food spicy?” Note: If you want to do the experiments along with us, congratulations, you can! You’ll need jellybeans, a blindfold and two pieces of dark chocolate. Listen, eat and yum! This episode is a collaboration with our friends at America’s Test Kitchen Kids!

Flavor facts: Why food is so delicious

What was the first lifeform like? What was the first fish or mammal? Is it even possible to know? In this episode, we look to the fossil record to help us trace our roots back to the Last Universal Common Ancestor. Paleontologist Neil Shubin joins us to talk about discovering a remarkably cool fossil that helped us understand how life evolved over billions of years. We also take a field trip to the Hall of Ancestors and examine a few branches on the tree of life. And we learn why figuring out how life began on earth could help us as we find life elsewhere in the universe.
