Neanderthal H. sapiens Brain Comparisons / Idiots



New insights into differences in brain organization between Neanderthals and anatomically modern humans

Eiluned Pearce, Chris Stringer, R. I. M. Dunbar

Previous research has identified morphological differences between the brains of Neanderthals and anatomically modern humans (AMHs). However, studies using endocasts or the cranium itself are limited to investigating external surface features and the overall size and shape of the brain. A complementary approach uses comparative primate data to estimate the size of internal brain areas. Previous attempts to do this have generally assumed that identical total brain volumes imply identical internal organization. Here, we argue that, in the case of Neanderthals and AMHs, differences in the size of the body and visual system imply differences in organization between the same-sized brains of these two taxa. We show that Neanderthals had significantly larger visual systems than contemporary AMHs (indexed by orbital volume) and that when this, along with their greater body mass, is taken into account,

Neanderthals have significantly smaller adjusted endocranial capacities than contemporary AMHs. We discuss possible implications of differing brain organization in terms of social cognition, and consider these in the context of differing abilities to cope with fluctuating resources and cultural maintenance. The assumption is that THE ONLY TOOL AVAILABLE to ANY SPECIES is this “magical” and probably imaginary social brain, which only H. sapiens possesses. No animal has ever coped with fluctuating resources and cultural maintenance = 500 million years of evolution was a total failure!

ASTOUNDING! Why do we hate Neanderthals? More to the point, Why are neurotypicals so blind to their own prejudice?

Does anyone ever consider that Neanderthals NEEDED visual processing MORE THAN they needed “social cognition”? These conclusions are ignorant  and shaped by modern social assumptions that we “beat the Neanderthals” and indeed caused their extinction. Why is this our ONLY INTEREST in Neanderthals? How infantile!
