Question:
How did the first reptiles evolve on Earth?
Answer:
About 300 million years ago, amphibians evolved into reptiles. These reptiles continued to adapt to their environment. They developed a better way of breathing than amphibians – amphibians breathe by moving their throat muscles, but the dinosaurs moved the muscles below the rib cage and abdomen, just like us. As a result, they could take in more air.
