General Organization. The cerebral cortex is the outer covering of gray matter over the hemispheres. This is typically 2- 3 mm thick, covering the gyri and sulci. Certain cortical regions have somewhat simpler functions, termed the primary cortices.eneral Organization. The cerebral cortex is the outer covering of gray matter over the hemispheres.

Neanderthals were shorter than modern man, with longer skulls, jutting brows and chins, and had large torsos with short limbs. They were not adapted for running and hunting in the same way as Cro-Magnon.
Neanderthal DNA is far more often found in Europeans and Asians than in Africans. If Neanderthals predated ALL humans, their DNA would be MOST prevalent in Africans. But not only were they first chronologically, Blacks were also the first builders of Civilization.
