Yaghan family

Their favourite position was squatting, which they adopted everywhere, inside and outside their huts and in the canoes. This posture stretched the skin around their knees giving them wrinkles when they stood up.
The Yaghan lived here successfully for 6,000 years before the arrival of Europeans in the 1800's which signalled the beginning of the end for them. They slowly began to die off due to disease as well as hunters and sealers depleting their food source. Their population of 3,000 dropped to 1,000 ten years after the Europeans arrived and by 1910 there were only 100 left. They're now extinct.
