Final answer:
Age, sex, and ancestry are three factors that can be identified with skeletonized human remains to make a personal identification.
Step-by-step explanation:
Three factors that can be identified with skeletonized human remains to make a personal identification are age, sex, and ancestry.
1. Age: Analysis of skeletal remains can provide important clues about the age of the individual at the time of death. This is done by examining various markers on the bones, such as growth plates in long bones or tooth eruption and wear patterns.
2. Sex: The examination of specific skeletal features, such as the shape and size of the pelvis or the presence of certain characteristics in the skull, can help determine the biological sex of the individual.
3. Ancestry: Skeletal traits associated with different geographic regions can be used to estimate the ancestral background of the individual. These traits include features of the skull, face, and long bones.
