Of all of the chordate groups, why are there only two amniote groups (reptilia and mammalia)?
◦ The other jawed vertebrates were not able to obtain enough food to survive the transition to land.
◦ Amniotes are the only chordate group that has successfully survived the transition to land.
◦ The other craniate groups had brains that were not developed enough to allow the organisms to develop tool-building survival skills.
◦ The vertebral columns of the other vertebrates were not strong enough to survive the transition to land.
