During the evolution of tetrapods, most of the traits criticial to the transition to land first evolved prior to tetrapods exiting the water. Identify one shared, derived (synapomorphic) trait for each of clade Vertebrates, clade Gnathostomes and clade Osteichthyans (3 traits in total) that were later important to the evolution of terrestrial tetrapods. Describe how the evolution of these three traits helped tetrapods overcome the challenges of life on land. **PLEASE BE DESCRIPTIVE AND PROVIDE FULL SENTENCES**
