Love Your Lineage Episode 7: The Impacts of Colorism (with Dr. David-James Gonzales) What does sunshine have to do with family history? Well, besides helping our plants and vegetables grow, sunshine has a profound effect on our bodies. One of those effects is melanin production. Melanin is a dark pigment in our hair, skin, and iris of the eye, that protects us from the sun’s radiation. Tragically, throughout history, some have used melanin to create caste systems that determine social status, ultimately affecting our family history. In this episode, Dr. David-James Gonzales discusses how these caste systems and resulting colorism began and the impact they still have on us as we seek to learn more about ourselves and our ancestors.
