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.
Neanderthals like the one depicted in this museum reconstruction died out tens of thousands of years ago. By Jennifer Viegas Discover News. The skeletal remains of an individual living in northern Italy 40,000-30,000 years ago are believed to be that of a human/Neanderthal hybrid, according to a paper in PLoS ONE.f further analysis proves the theory correct, the remains belonged to the first known such hybrid, providing direct evidence that humans and Neanderthals interbred. Prior genetic research determined the DNA of people with European and Asian ancestry is 1 to 4 percent Neanderthal.
