Over half a billion years ago life on earth took an incredible step in evolution, when animals learned to build skeletons. Manifesting in a vast variety of forms, they provided the framework for sophisticated networks of life that fashioned the evolution of Earth's oceans, land, and atmosphere. Using many different materials, from calcium carbonate and phosphate, and even silica, to make shell and bone, they started creating the support structures that are now critical to most living forms, providing rigidity and strength.
The earliest bacterial colonies constructed large rigid structures - stromatolites - built up by trapping layers of sediment, while the Within a few tens of millions of years, all of the major types of skeleton had appeared.Skeletons enabled an unprecedented array of bodies to evolve, from the tiniest seed shrimp to the gigantic dinosaurs and blue whales.
