Write a 1,000-word autobiographical essay that describes and reflects back upon your experiences as you came to understand human phenotypical variation. Did you grow up in a diverse neighborhood or town? What is your earliest memory of encountering a real, live person who looked different from you? How did you react to them, emotionally, intellectually, and behaviorally? How was this variation explained to you by adults or in books, as you began to ask questions? How did your understanding of phenotypical variation grow and change over the years?
