24 - Why do some animals live in water and others on land?

A long time ago, the Earth was all water, and life started in the ocean. Over time, some animals adapted to living in the water and became good at swimming, like fish.

As the Earth changed and land appeared, some animals adapted to living on land, like humans and animals with four legs. Their bodies changed to help them breathe air, walk, and find food on land.

Now, each type of animal has special features that help them survive in their own world, whether it's in the water or on land.
