This podcast interviews Tina Lasisi, a biological anthropologist, about her research on the evolution and genetic basis of human hair and skin variation. The interview begins with Lasisi's background and how she became interested in the field, then delves into the scientific explanations for variations in skin and hair color, focusing on the roles of melanin and UV radiation. Lasisi discusses her research on how tightly curled hair reduces heat gain from solar radiation and the challenges in measuring and categorizing hair types accurately. Finally, the discussion touches upon the potential of hair analysis for understanding physiological processes and biomarkers. The interview highlights the complexity of understanding human hair variation and the ongoing research needed to fully explain it.
