Why Marine Armour Evolution Backfired

Why Marine Armour Evolution Backfired ? 400 million years ago, during the Devonian period, the ancient oceans were filled with heavily armored animals — prehistoric armored fish covered in bony plates. Creatures like the placoderms and the massive Dunkleosteus dominated these seas, protected by extreme natural armor and jaws powerful enough to crush almost anything. But today, after millions of years of animal evolution and natural selection, most animals are soft, fast, and seemingly fragile. Why did evolution favor speed over armor? In this video, we explore the evolutionary trade-offs that led animals to ditch heavy protection and rely on speed, intelligence, and camouflage instead. Learn about: • How armor worked in the past and why it was so effective • The costs of armor for energy, mobility, and reproduction • Real-life examples: stickleback fish, sharks, turtles, armadillos, and pangolins • How predators and environmental changes shaped evolution Discover why evolution favors adaptability over brute defense, and why most animals today are “fragile but fast and smart.” If you love evolutionary mysteries and wildlife, don’t forget to like, comment, and subscribe!
