Ecologically, it is split into separate northern and southern subsystems by a zone of intense perennial upwelling near Lüderitz (26–27.5°S; Shannon 1985).

The sequencing of entire human mitochondrial DNAs belonging to haplogroup U reveals that this clade arose shortly after the "out of Africa" exit and rapidly radiated into numerous regionally distinct subclades. Intriguingly, the Saami of Scandinavia and the Berbers of North Africa were found to share an extremely young branch, aged merely approximately 9,000 years. This unexpected finding not o...
