Discuss the development of early vertebrates into advanced fish and, finally, into amphibians. What body changes
were required to accomplish this move from the marine environment to land? What will be an ideal response?
The student should discuss the changes from early fish into more advanced fish with the
development of jaws. This adaptation allowed jawed fish to breathe more efficiently, chew
food, and become active predators. The jawed fish developed into the lungfish and lobefinned
fish, which eventually developed into the amphibians. These amphibians had the
ability to breathe air and move on land, but they were limited to environments close to the
water because they had to return to the water to reproduce.
