Question

What broad category of animals shows adaptations from water-dwelling to land-dweller, including the ability to breathe air and legs to move on land?

Answer 1

amphibians

Amphibians! In order for water-dwelling animals to adapt to life on land, many new adaptations had to take place. First, they needed to be able to breathe air instead of obtaining oxygen from water. And fins don't work well as legs! They needed to be able to move around well on land.
