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.

What are denticles and how do they relate to shark scales and human teeth?

Describe the evolutionary significance of the transition from toothless mouths to the development of teeth in vertebrates.

How did the evolution of jaws contribute to the predatory capabilities of fish?

In what ways did the development of teeth allow for more efficient digestion compared to animals that swallowed food whole?

Explain how the teeth of different dietary groups (herbivores, carnivores, omnivores) evolved to suit their feeding habits.
