Complex animal life 10M years older than thought, originated in deep sea

Half a billion years before the present, in the lightless depths of an ancient ocean, creatures were already moving, sensing, and reproducing — a full ten million years before science believed such complexity was possible. Fossils unearthed in northwestern Canada have quietly rewritten the opening chapter of animal life, relocating its cradle from sunlit coastal shallows to the cold, pressured dark of the deep sea. The discovery does not merely adjust a date; it reminds us that the archive of life is far larger than the fragments we have so far learned to read.
