The term is most often used in connection with scientific descriptions of classic Neanderthal crania. While common among many of mankind's ancestors, primarily robust relatives rather than gracile, the protrusion is relatively rare in modern Homo sapiens.

Some scientists suspect occipital buns might correlate with the biomechanics of running. Another theory attributes them to enlargement of the cerebellum, a region of the cortex which mediates spatial reasoning, motor function, and many aspects of brain wave patterns, including gamma waves.

There are still many human populations which often exhibit occipital buns. A greater proportion of early modern Europeans had them, but prominent occipital buns even among Europeans are now relatively infrequent. They are still found fairly often among Lapp and Finn individuals. Bushmen fr
