Roebroecks is right to be skeptical about the sort of comparisons made in the table. For example, it seems very likely that Neanderthals had throwing spears as well as thrusting spears--a "projectile technology," albeit without hafted stone spearheads. We know this because of some beautifully made wooden throwing spears found in a coal mine in Germany, aerodynamically tapered, and dated to 400,000 BP. They were therefore made not by Neanderthals but by their precursors, homo heidelbergensis. The point is the sheer unlikelihood that such spears would first be preserved and then be found. A single find like this can make mincemeat of generalizations about Neanderthal intellectual and technology capacity, and shows just how suspect generalizations about their language ability can be, if based on inferences from their technological capacity.
