Fossils of ancient fish, including lungfish, have been found that may provide insight into how life began moving onto land around 400 million years ago. The discovery of these fossils is rewriting the story of life on land, although the exact timeline and details of this transition are still unclear, with some reports suggesting that other creatures, such as millipedes, may have beaten vertebrates to land. The fossils are also shedding light on the evolution of various ancient animals, including those that ate plants on land and possibly even the origins of certain body parts.
