Habitat for Humanity

摘要

Along cairn of black stones marks the spot where a skeleton of Ardipithecus ramidus was found, its bones broken and scattered on a barren hillside. Erected as a monument to an ancient ancestor in the style of an Afar tribesman's grave, the cairn is a solitary marker in an almost sterile zone, devoid of life except for a few spindly acacia trees and piles of sifted sediment.
