So far it is known, that starting in Africa, the spread of anatomically modern humans took until 14,000 years before they reached the south American continent. Fossil human hair, which was found by our local cooperation partners in the "Cueva Cacao" in northwestern Argentina, may hint to a much earlier occupation (>43,000). Using a series of radiocarbon datings from different layers of the cave sediments, including the one containing the fossil hair, we would like to study the stratigraphy of these sediments. The results may prove the early human occupation of that cave.

到目前为止，我们所知道的是，解剖学上的现代人从非洲开始传播，直到14000年才到达南美大陆。我们当地的合作伙伴在阿根廷西北部的Cueva可可发现了人类头发化石，这可能暗示了更早的人类活动（距今43000年）。利用一系列来自洞穴沉积物不同层的放射性碳定年，包括含有化石头发的层，我们想研究这些沉积物的地层学。这些结果可能证明早期人类曾在那个洞穴居住过。
