Abstract: Abstract The human skull offers a rigid unit for the study of past populations and for personal identification. Consisting of at least 21 individual bones, united according to anatomical principles peculiar to man, the skull develops during childhood and youth to reach a size and expression which in general, but not completely in detail, may be regarded as final. Because of genetical differences between the major races of the world (Caucasian, Mongoloid, Negroid), principal differences in the appearance between typical skulls from these groups may easily be pointed out in terms of morphology. These differences are the result of different kinds of skull growth in the different groups, and may be expressed in terms of facial flatness, cranial indices, or degrees of prognatism. By tradition in craniometry, and more or less supported by direct or indirect evidence such as historical records, differences in mean skull measurements between subpopulations from neighbouring geographical regions are similarly regarded as expressions of population differences related to differences in the genetic composition of the populations.
