Corals (Antozoons) are invertebrate organisms that are known to have lived since the Cambrian Period (543 to 490 million years ago), and of which there are many fossil specimens dating back to the Ordovician period (490 to 443 million years ago). Corals come in various types; soft, horny, spiny and true corals. Coral beds form as a result of coral skeletons accumulating in a specific location over thousands of years. Corals live either alone or in colonies. They tend to live in warm seas, attached to large rocks on the sea bed, though free-moving, newly-hatched ones are rarely encountered.Corals deal a severe blow to Darwinism, given their sophisticated structures that have remained unchanged for hundreds of millions of years. Like all other living things, they are the work of our Lord"s sublime creation.
