This important but often neglected evolutionary question is central to the work of Tina Lasisi, a biological anthropologist at the University of Southern California. In this SciCafe, Lasisi will tease out the mysteries behind why humans have scalp hair and why we may have developed different hair textures as we’ve evolved. She will share the unique methods used in her research, including the use of robots with wigs to understand the thermoregulatory role of scalp hair and its protection against solar radiation, as well as her insights on why tightly curled hair is unique to our species.
