Exam 7: Attribution of Ancestry

A lower jaw is found that has a rounded chin, vertical ascending ramus, enamel extensions on the molars, and a tuft of black hair. What is the most likely ancestral group of this individual?

There are four indexes of the face that aid in the attribution of ancestry.

The nasal bridge of Asians projects more than that of Whites.

The shape of the upper jaw of Asians is intermediate between those of Whites and Blacks.

Which part of the cranial skeleton is most useful for attributing ancestry?

A skull is discovered with a sharp lower border of the nose, medium nasal spine, low nasal bridge and circular eye orbits. What is the most likely ancestral group of this individual?

A male skull is found and measured so that discriminant functions can be used to determine race. If the White versus Black function indicates White and the White versus Native American function indicates Native American, what is the most likely ancestral group of this individual?

Prognathism (jut of the jaw) is a characteristic normally associated with Whites.

A femur has a straight shaft, mild torsion of the head and neck, a Platymeric Index of 90 and a positive value from the Platymeric Index discriminant function. What is the most likely ancestral group of this individual?

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

A partial skull is found that contains only the eye orbits, which are spaced widely apart. What is its most likely ancestral group?

A skull is discovered with a dull lower border of the nose, large nasal spine, low nasal bridge and pronounced jut of the jaw. What is the most likely ancestral group of this individual?

The tibia has several characteristics that aid in the attribution of ancestry.

The same discriminant functions can be used to attribute ancestry in males and females.

A femur is discovered that has an anteriorly curving shaft, mild torsion of the head and neck, and an intercondylar shelf of around 150. What is the most likely ancestral group of this individual?

The most useful structure of the cranial skeleton for determining ancestry is the vault.

There are no characteristics of the jaw that can be used to assess ancestry.

The lower border of the nose in Blacks has a distinct sill.

Later the nasal area of the above skull is found that has a Category 1 Inferior Nasal Aperature. Considering both structures, what is its most likely ancestral group?

A skull is found with a Maxillofrontal Index of 50, Zygoorobitral Index of 45 and an Alpha Index of 70. What is the most likely race of this individual?
