Neanderthals are commonly thought to have relied on dangerous close range hunting techniques, using non-projectile weapons like the thrusting spears depicted here; this hunting approach is thought to have brought them into violent contact with large mammals, resulting in high levels of injury especially to the head and neck when compared to modern humans; Beier et al found similar head injury levels in both Neanderthals and Upper Paleolithic humans, casting doubt on this hypothesis.
