In the grand theatre of defensive evolution, few strategies appear more disparate than the hedgehog's 7,000 keratin spines and the Hulk's unlimited rage-fuelled regeneration. One represents millions of years of careful evolutionary refinement; the other, a catastrophic laboratory accident that somehow worked out rather well. Yet both organisms share a fundamental purpose: survival against overwhelming odds.
This analysis examines two remarkably different approaches to the same existential problem. The hedgehog, weighing approximately 700 grams when fully grown, has thrived across Europe, Asia, and Africa for some 15 million years. The Hulk, by contrast, emerged in 1962 and has since become one of the most formidable entities in any known universe. One hibernates through winter; the other punches gods through mountains.
