       This is a Chotdate Cladogram. It shows the evolutionary relationships among different organisms, so first we have the chordate. The chordate is an invertebrate, well sometimes. Chordates have a notochord, dorsal nerve chord, pharyngeal slits, endostyle, and a muscular tail. But now, here are the vertebrates.Included in the chordates are vertebrates. The vertebrates have a spinal cord and backbone. The fish have gills andfins that allow them to live under water. Amphibians evolved next , same as the fish, they start off in the water. But as the amphibian matures, it can live on land, so amphibians can live on both land and water. Next are reptiles, unlike amphibians, they start off on land. Reptiles can also lay eggs, just like birds can. Birds are the only vertebrate capable of flight and they also have feathers. Finally, are the mammals. Mammals produce milk to feed their young. They also have fur all over their bodies.
