Notes Bones 26: Stature & Ancestry

Biological profile

1. Skeletal inventory

2. Age (Cranial sutures, fusion, dental eruption, basillar suture)

3. Sex

4. Pathology

5. Distinguishing features (Dental variation)

6. Stature: using the long bones equation

7. Ancestry: 1/3 of genes have to do with stature

Human variation is Clinal with respect to geography

• Cline: gradual change in character or feature across distributional range of a species

90% of gneetic variants are shared across regions, but 10% of variation is private

• Variation is found more in the same region rather a far away region.

As time passes, categories of race increase

1. race is cultural

2. variation is clinal

East asian & Native americans have incisor shoveling more

• But there is no certainty
