A dome home so efficient, nomads never bothered upgrading for centuries.

means A dome-shaped dwelling made of a pole framework covered with bark, mats, or hides, traditionally built by various Indigenous peoples of North America.

from From Eastern Abenaki 'wikewam' (also appearing in related Algonquian languages), literally meaning 'their house' or 'dwelling,' built from a root related to 'wik-' meaning 'to dwell.' English settlers borrowed the word in the 17th century, though they often mistakenly extended it to mean any Native American dwelling — including the very different tipi, which comes from Lakota. The mix-up stuck in popular use even though wigwam and tipi are distinct structures from distinct peoples.
