Three hundred and seventy-five million years ago,the weather became very hot.Many years went past with little or no rain.The lakes became dry,and many fish died.
Some kinds of fish were able to move to the new places without water.These fish could breathe（呼吸）on land also in the water.In the next four or five million years,they slowly changed and became the first animals.They lived sometimes on land and sometimes in the water.Three hundred million years ago,the weather changed.It was still hot,but it rained a lot.So the first animals lived in or near the lakes,and they could eat fish in those lakes.
