Discuss the problems that animals had to overcome to adapt to the land environment. How did
they overcome these problems? Provide specific examples of these adaptations. What will be an ideal response?
Because animals evolved in a moist environment, they had to adapt to the drying effects of the
atmosphere by acquiring an outer covering for protection. They also had to develop a means to
extract oxygen from the atmosphere rather than from water. Because animals need mobility to
find food, they also had to develop a means of locomotion and a skeletal structure for support.
Their reproductive strategy moved toward internal fertilization since gametes were no longer
dispersed in water, and they had to combat the problems of desiccation of unprotected eggs.
