What Vitamin D Has to Do With Skin Color

Why do humans have different skin colors? The answer starts with the sun. In this illustrated story, we follow our ancestors from the sunlit savannas of Africa to the cold, snowy lands of the north, and uncover how sunlight, melanin, and vitamin D shaped the skin tones we see around the world today. Here's what you'll learn: ☀️ How melanin works as the body's natural sun protection 🦴 Why too little sunlight became a survival problem far from the equator 🧬 How UV light and vitamin D pulled skin color in opposite directions 🌍 How migration, climate, and diet changed human skin over many generations 🧩 Why skin color is just one small variation in a much bigger biological story Skin color isn't random, and it isn't a sign of anything except adaptation. It's the result of people living in different environments and our bodies adjusting to them over thousands of years.
