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.
At least one-fifth of the Neanderthal genome may lurk within modern humans, influencing the skin, hair and diseases people have today, researchers say. Although modern humans are the only surviving human lineage, other groups of early humans used to live on Earth.iew full size image. If you are 2 percent Neanderthal and I'm 2 percent Neanderthal, we might not have the same Neanderthal DNA between us, said study lead author Benjamin Vernot, a population geneticist at the University of Washington in Seattle. We might have inherited different portions of the Neanderthal genome.
