Exam 7: Attribution of Ancestry

A skull is discovered with a low nasal bridge, wide face, projecting lower border of the eye, and small browridges. What is the most likely ancestral group of this individual?

The shape of the eye orbits does not aid in the attribution of ancestry.

It is not surprising that discriminant functions would use the width of the nose in the attribution of ancestry.

The terms White, Black, Hispanic, Asian and Native American are categories of people that are used by law enforcement officials.

The most common ancestral group in the United States is White.

When a decomposed body is found and before any analysis is done, what is its most likely ancestry?

A skull is discovered with a femur. The Maxillofrontal Index is 25, the Zygoorobitral Index is 20 and an the Alpha Index is 40 while the Platymeric Index is 70. What is the most likely ancestral group of this individual?

The nasal spine is largest in Whites of all of the other groups.

A femur has a Platymeric Index of 70 and a negative value from the Platymeric Index discriminant function. What is the most likely ancestral group of this individual?

A lower jaw is found with a femur; the chin is rounded and the Platymeric Index discriminant function value is negative. What is the most likely ancestral group of this individual?

The Platymeric Index can be entered into a discriminant function to attribute ancestry.

The nasal root in Whites is narrower than that in Blacks.

A lower jaw is found that has a pointed chin, a slanted ascending ramus, and a no enamel extensions on the molars. What is the most likely ancestral group of this individual?

Blacks can have a depression behind bregma that is not usual in Whites and Asians.

A skull is discovered with a sharp lower border of the nose, straight facial profile, heavy browridges and spatulate upper incisors. What is the most likely ancestral group of this individual?

A skull is discovered with a sharp lower border of the nose, large nasal spine, projecting nasal bridge and narrow nose. What is the most likely ancestral group of this individual?

There are direct measurements, indexes and discriminant functions that aid in the attribution of ancestry.

There are both anthroposcopic and metric methods for attributing ancestry.

A female skull is found and measured so that discriminant functions can be used to determine race. The values calculate to 85 on the White-Black scale and 125 on the White-Native American scale. What is the most likely ancestral group of this individual?

Hair and skin color of decedents can be used, with caution, to attribute ancestry.
