Imagine a world 558 million years ago, where the OG animals like Dickinsonia (basically a giant, ribbed pancake) cruised ancient seas. Then came the Cambrian Explosion—a literal party of new life forms, including the first predators with wild body parts and the first creatures to rock hard shells. Sponges, symmetry, and even baby vertebrates all made their debut. These ancient weirdos set the stage for every animal on Earth today! #Science #AncientLife #Evolution
