Cranial and postcranial morphology contribute to which aspects of the biological profile?

• A. Ancestry, Sex, and Age
• B. Diet, Personality, and Activity
• C. Eye Color, Hair Color, and Skin Type
• D. Geographic Origin, Language, and Occupation

Answer: (A)

Cranial and postcranial morphology are used to build the biological profile by assessing ancestry, sex, and age. Ancestry is inferred from population-typical skull features (such as nasal shape, orbital form, and vault characteristics) and from pelvic and long-bone patterns that show population variation. Sex estimation relies on dimorphic traits observed in the skull (like brow ridges, mastoid process, and nuchal crest) and in the pelvis and other bones, where overall robustness and shape differ between sexes. Age is determined through development and degeneration: in younger individuals, dental eruption and epiphyseal fusion patterns are informative; in adults, cranial suture closure and joint degenerative changes provide age indicators. These aspects are what cranial and postcranial morphology can reveal about the biological profile, whereas diet, personality, and activity, or eye/hair/skin characteristics and language or occupation, are not reliably inferred from skeletal morphology.
