How & What Animals Eat
Season 1
Episode 4
Animals have evolved to eat a lot of different things, even stuff that barely passes for food, and it shapes our entire lives from what we look like to where we live. Today, we’ll talk about why being a carnivore is just easier than being a herbivore, why there are so few omnivores out there, and dedicate a little time to the remaining 2% of animals that really push the definition of food.
