Archaeological discoveries can also boost political support for a case back home. "When remains or objects are found in the ice, I could see straight away it would inflate territorial nationalism," says Dodds. "Archaeology has always been really important for national politics."
Other events, such as historic shipwrecks, could play a similar role as the Yamana skull. In 1819, the Spanish frigate San Telmo was wrecked in the Drake Passage, which separates the tip of Chile from the Antarctic Peninsula. Archaeologists have searched the Antarctic islands for signs of whether any crew made it alive to the shore.
