Chapter 10: Estimating Ancestry in Human Skeletal Remains

Ancestry

Refers to the biological profile component that helps in identifying individuals based on genetic differences.

Phenotype

The outward appearance of an organism, which in humans involves features influenced by genetics and environment.

Forensic anthropology

The field that applies anthropology and related disciplines to legal contexts, especially in identifying skeletal remains.

Non-metric traits

Traits evaluated based on their shape, size, and presence or absence, used in predicting ancestry without precise measurements.

Metric approach

An ancestry estimation method that relies on well-defined cranial measurements for more objective analysis.

Cranial examination

Focus on studying the skull, particularly the mid-face region, to infer ancestral background.

Ossa (Optimized Summed Scoring Attributes)

A scoring system used to classify skeletal remains as African or European ancestry based on selected traits.

Homo sapiens

The scientific classification for modern humans, introduced by Carolus Linnaeus.

Genetic variation

Differences in DNA sequences among individuals, which can influence phenotypic traits.

Ancestry Informative Markers (AIMs)

Specific molecular markers used to provide insights into an individual's ancestry.

Cultural factors

Aspects related to historical and social influences that can impact the interpretation of ancestry.

Social race

Categories of race defined by social and cultural factors rather than strict biological differences.

Linnean classification

The system created by Carolus Linnaeus that organized species, including humans, based on geographical variation.

Gene flow

The transfer of genetic information between populations, contributing to genetic diversity.

Population genetics

The study of genetic variation within and between populations, revealing important aspects of ancestry.

Morphoscopic traits

Traits assessed based on observable morphology, significant in non-metric approaches to ancestry estimation.

Cranid and FORDISC

Software used in forensic anthropology for estimating biological ancestry through cranial measurements.

Validation studies

Research necessary to confirm the accuracy and applicability of methods used in ancestry assessments.

Cranial metrics

Measurement techniques applied to the skull for estimating ancestry based on quantified traits.

Native American classification

The categorization of Native Americans in previous anthropological studies, often leading to oversimplification.
