Write the biological reasons why man’s ears and mouth have developed the way they are now. |

Answer» Ears are sense organs that interpret sounds. Two ears will function better by capturing sounds from everywhere. Mouth is basically for feeding in all animals. It should be a single one. It then leads to food pipe to carry swallowed food inside the body. With a single mouth, feeding is easier. However, ears should be two to gather all sound signals. |
