ABSTRACT
No two skeletons are the same. Firstly, bones and teeth differ in size and shape between individuals. This type of variability, the subject of the present chapter, lends itself to recording by measurement, and so is called metric variation. Skeletons also differ in ways which are much more difficult to measure. This type of variability takes the form of minor anomalies of the bones and teeth. These sorts of variants, termed non-metric traits, are discussed in the next chapter.
