Imagine your body is like a canvas, and every part has its own special color, some parts are more hairy, others less so. This weird pattern isn’t random; it helps our bodies stay warm, feel comfortable, or even look cool! Scientists think this happens because of tiny instructions in our genes that were passed down through generations.
Examples
- Your uncle has thick hair on his chest and back but almost no hair on his face.
- Some people have really curly eyebrows and very straight nose hairs.
