Why has Antarctica had a human presence only since the 19th century?

The absence of a human presence in Antarctica until the 19th century is primarily due to the continent's extreme environmental conditions and its geographic isolation. Antarctica is the world's coldest, windiest, and driest continent, with approximately 98 percent of its landmass covered by a vast ice sheet. These harsh conditions, combined with the lack of native terrestrial resources, made the region inhospitable to human settlement throughout the history of Homo sapiens.1

Furthermore, the ice-choked and stormy seas surrounding the continent long hindered exploration by wooden-hulled ships. While Polynesian oral tradition suggests early sightings of the region, the first confirmed discovery of the continent did not occur until 1820, following the expansion of sealing and whaling activities into the Southern Ocean.12

Unlike other regions of the world that were settled by early humans, Antarctica remained isolated from human migration routes. It was not until the 19th century that advancements in maritime technology allowed explorers to penetrate the Southern Ocean, and it was only in the mid-20th century that scientific research replaced commercial exploitation as the primary driver for a sustained human presence.1
