Anatomical Features

Anatomical features are the bodily structure of a living thing. Examples of an anatomical feature is eyes, nose, mouth, hair, etc. Scientists use these features to determine if evolution has occurred. Evolution is the change in these inherited characteristics over time. The scientist can use these features to tell if evolution has occurred because if the anatomical feature of an animal change over time that means that evolution has occurred. For example if a dogs anatomical features have changed it means that evolution has occurred. They can tell that it has occurred because animals anatomical features change when they have to adapt to their environment when something changes like the climate, a flood, or a drought. Like when a flood occurs the animals on land have to adapt to living in the water, which is when evolution occurs and if they don't adapt then that species will become extinct. Always if the animals that lived in the desert needed a lot of water to live they would have to adapt to the environment because the dessert doesn't have a lot of water.
