Okay, so I see that the items were found in the layers indicating the time in which they were made, but is there any real evidence pointing to who created them? Did they find tools alongside the object that would have been used to make them? I’m thinking maybe the Neandertals could have taken them from modern humans either by force, as hunting trophies perhaps, or even through trade. Wouldn’t that be something, if we once traded with Neandertals. What if they misundertood our intentions and traded all their territory for a few bone baubles...
Neandertals were around much earlier, and made tools long before a few CroMagnon trickled uphill from areas now submerged — the continental shelf, not Africa, is, after all, the homeland(s) of our ancestors.
