Abstract
- The cranium from Broken Hill (Kabwe) was recovered from cave deposits in 1921, during metal ore mining in what is now Zambia.sup.1. It is one of the best-preserved skulls of a fossil hominin, and was initially designated as the type specimen of Homo rhodesiensis, but recently it has often been included in the taxon Homo heidelbergensis.sup.2-4. However, the original site has since been completely quarried away, and--although the cranium is often estimated to be around 500 thousand years old.sup.5-7--its unsystematic recovery impedes its accurate dating and placement in human evolution. Here we carried out analyses directly on the skull and found a best age estimate of 299 [plus or minus] 25 thousand years (mean [plus or minus] 2[sigma]). The result suggests that later Middle Pleistocene Africa contained multiple contemporaneous hominin lineages (that is, Homo sapiens.sup.8,9, H. heidelbergensis/H. rhodesiensis and Homo naledi.sup.10,11), similar to Eurasia, where Homo neanderthalensis, the Denisovans, Homo floresiensis, Homo luzonensis and perhaps also Homo heidelbergensis and Homo erectus.sup.12 were found contemporaneously. The age estimate also raises further questions about the mode of evolution of H. sapiens in Africa and whether H. heidelbergensis/H. rhodesiensis was a direct ancestor of our species.sup.13,14. Analyses of the hominin skull from Broken Hill, Zambia, place it at an earlier date than previously thought, confirming that later Middle Pleistocene Africa was home to at least three lineages of hominin.<br />Author(s): Rainer Grün [sup.1] [sup.2] , Alistair Pike [sup.3] , Frank McDermott [sup.4] , Stephen Eggins [sup.2] , Graham Mortimer [sup.2] , Maxime Aubert [sup.2] [sup.5] , Lesley Kinsley [sup.2] [...]
