Come dive into one of the curiously delightful conversations overheard at National Geographic’s headquarters, as we follow explorers, photographers, and scientists to the edges of our big, weird, beautiful world. Hosted by Peter Gwin and Amy Briggs.


Wayfinding Through the Human Genome

National Geographic Explorer Keolu Fox grew up hearing stories about his ancestors, Polynesian navigators, and the men who in the late 1970s led the first Hōkūleʻa voyage to Tahiti. As the first Native Hawaiian with a Ph.D. in genomic sciences, Fox tells us how genetic data can help reveal powerful narratives about the history of Indigenous people and their achievements, and empower communities to use data to improve public health and preserve their culture.
