Me i don't understand what its asking! i will give a brainlist for who answers and explains it. refer to the chordate cladogram above to answer the following questions. 1. list the adaptation that all vertebrates have in common. 2. list all the adaptations that your chordate has (as shown on the cladogram). 3. to which type of chordate is your chordate most closely related? 4. why do you think endothermy appears at two points on the cladogram? 5. amniotic eggs have a waterproof membrane. what type of animals evolved from animals that lay amniotic eggs? 6. in what type of habitat do you think the evolution of amniotic eggs animals survive? hint: in what habitat do all animals without amniotic eggs live? when it asks about the chordate that is mine, i choose a frog.
