Survival in extreme environments hinges on culturally accumulated knowledge, not individual capacity.

Evidence

Why couldn’t these men survive, given that some humans do just fine in this environment? King William Island lies at the heart of Netsilik territory, an Inuit population that spent its winters out on the pack ice and their summers on the island, just like Franklin’s men. In the winter, they lived in snow houses and hunted seals using harpoons. In the summer, they lived in tents, hunted caribou, musk ox, and birds using complex compound bows and kayaks, and speared salmon using leisters (three-pronged fishing spears; see figure 3.1 ). The Netsilik name for the main harbor on King William Island is Uqsuqtuuq , which means “lots of fat” (seal fat). 3 For the Netsilik, this island is rich in resources for food, clothing, shelter, and tool-making (e.g., drift wood). — Joseph Henrich, The Secret of Our Success, 107

Categorization

• XREF: Contrast with lone-survival narratives from books like Krakauer’s Into the Wild or Shackleton accounts; also connects to the broader thesis of cultural-evolutionary accumulated expertise earlier in this book. — connects to: Sustaining and transporting fire demands culturally transmitted skill — Joseph Henrich, The Secret of Our Success: How Culture…, 228; Culture supplied the water capacity that genes alone could not, enabling endurance running adaptations — Joseph Henrich, The Secret of Our Success: How Culture…, 256; Forager water-procurement know-how is nonobvious cultural knowledge that genes could not supply — Joseph Henrich, The Secret of Our Success: How Culture…, 255 (+11 more)
• SHARE: The Netsilik name for the island meaning ‘lots of fat’ (seal fat) is a nice concrete detail to share with someone interested in Inuit ecology or toponymy.
