Animal Adaptations and Evolution Concepts

The Scishow Talk Show features Callie Moore discussing her work with Eons and a collaboration with the Smithsonian. They explore the significance of ammonites and fossils, touching on the ethics of fossil trade. The show also compares hedgehog and porcupine features, highlighting convergent evolution and animal behavior.
