Why Sharks Are Covered In Teeth

The video explores the evolutionary link between shark scales and teeth, highlighting how early vertebrates developed protective armor that evolved into scales and eventually teeth. It discusses the transition from passive filter-feeding to active predation with the development of jaws and teeth, leading to the rise of modern sharks and land vertebrates. The diversification of teeth allowed vertebrates to adapt to various diets, with specialized teeth for herbivores, carnivores, and omnivores, all tracing back to ancestral scales.
