"Tierra del Fuego was inhabited by three unrelated groups: Ona, which lived by gathering wild fruits and guanaco hunt; Yahgan in islands south of the Isla Grande (Great Island) of Tierra del Fuego, and Alacaluf (inhabiting the Strait of Magellan - Brunswick Peninsula, Wellington, Santa In�s and Desolaci�n islands). The last two groups lived by gathering sea products and fishing. All these groups did not know farming, weaving, skin tanning, pottery and basket making. The fisherman groups did not know the fishing hook and nets, while the Onas, inhabiting an island surrounded by fish-rich waters, did not fish and nor even did they swim. "

But anyway, that’s an excellent example, one of the most remote places on Earth, and three unlike cultures wound up stuffed in there.
