👤 whose
Whose discovery showed that coral reefs are built by tiny animals rather than plants or rocks alone?
Quick Answer
Charles Darwin helped explain coral reef formation during and after the voyage of HMS Beagle. He argued that reefs grow from coral animals in warm, shallow seas over long periods.
The Full Story
Charles Darwin’s observations in the 1830s led him to a major insight about coral reefs. He realized that reefs are built by living coral polyps, tiny animals that secrete calcium carbonate skeletons. Darwin also proposed a theory of atoll formation: reefs can grow around sinking volcanic islands, leaving ring-shaped reefs behind. His ideas, published in 1842, became foundational to modern coral-reef science.
Key Facts
1.Darwin published his coral reef theory in 1842
