Jointed fins with strong muscular support allowed lobe-finned fishes to have greater control and flexibility in moving their fins, which is important for movement on land. This adaptation eventually led to the development of limbs in amphibians. Flattened scales, jaws with teeth, cartilage skeleton, and notochord are also important adaptations in vertebrates but not specifically related to the transition to life on land.
