Abstract

A convoluted surface pattern of ridges and grooves characterizes the frontal torus in adult Neandertal fossils. Modern human skulls rarely have the pattern well developed. It is not observed in postcranial bones, nor in skulls of Neandertal children. This vermiculate bone is resistant to oriented cracking from weathering or fractures. Structural characteristics of the bone give evidence on the problem of the function of hominid brow ridges.

摘要

成年尼安德特人化石的额骨隆突具有一种由脊和沟构成的复杂表面形态。现代人类头骨很少有这种发育良好的形态。在颅后骨骼中未观察到这种形态，在尼安德特儿童的头骨中也未观察到。这种蠕虫状骨骼能抵抗因风化或骨折导致的定向开裂。骨骼的结构特征为原始人类眉脊的功能问题提供了证据。
