Study Notes

Paleopathology

The study of ancient disease and illness, examining conditions that disrupt typical biological function.
Includes traumatic injuries, infectious diseases, joint diseases, congenital anomalies, cancer, and more.

Differential Diagnosis

The process of identifying evidence of disease and diagnosing the most likely cause based on evidence.
Distinguishing abnormal bone morphology from normal human skeletal variation is crucial.
Bone characteristics like porosity and remodeling vary based on age and skeletal element, requiring careful analysis.

Bone Response to Abnormal Conditions

Bone reacts to abnormalities like infection or trauma by forming new bone (if broken), resorbing existing bone, or both.
Skeletal pathologies are carefully described, noting abnormal bone growth or formation, often associated with chronic conditions.

Identifying Skeletal Lesions

The skeletal elements involved and their distribution across the body provide clues about the disease.
Different diseases can have localized or widespread impacts, affecting specific areas of the body.
Determining whether lesions are active (no evidence of healing) or healed (evidence of bone remodeling) indicates whether the individual survived or died with the disease.

Paleopathology and Bioarchaeology

Paleopathological analyses are enhanced by considering social roles, status, activity patterns, diet, and other factors that influence disease exposure and morbidity within a society.

Non-Specific Stress Indicators

Disease processes that cannot be linked to a specific condition or pathogen but show disruption of normal biological function.
Examples include periosteal reaction (bone growth), osteomyelitis (bone loss), and cribra orbitalia and porotic hyperostosis (porosity).

Trauma

Includes fractures (partial or complete bone discontinuity), dislocations (separation of bone ends at a joint), and body modifications (deliberate alterations of the human body).
Fractures can be complete or incomplete, with different patterns reflecting the mechanism of injury (blunt force, sharp force, high velocity).

DNA Sequencing

Involves DNA extraction, purification, quantification, and sequencing using machines.
Bioinformatic analysis of the sequence data allows for various questions about the DNA to be answered.

Applications of DNA Sequencing

Different types of DNA sequences are used to address various research questions:
- Mitochondrial (mtDNA): Used for population genetics and ancestry tracing.
- Y-DNA: Found only in biological males and used for paternal lineage studies.
- Nuclear DNA: Inherited from both parents and used for individual and population-level studies.
- Ancient DNA (aDNA): Used to study past populations, disease, migration patterns, and more.
- Metagenomic: Sequencing all genomic material in a sample, revealing multiple species present.
- Environmental DNA (eDNA): Used to study past environments and organisms, including those without skeletal remains.

Parasitology

Studying parasites is crucial for understanding disease in skeletal remains, providing insights into ancient environments and how people interacted with them.
Parasites can reveal stressors experienced by individuals, as they can drain energy and resources from the host.
Types of parasites include ectoparasites (living outside the host), helminths (parasitic worms), and protozoans.

Stable Isotope Analysis

Stable isotopes provide insights into the chemical composition of an individual's diet, revealing their consumption of terrestrial vs marine foods, C3 vs C4 plants, and trophic levels.

Malnutrition

Shifts towards reliance on carbohydrate-rich foods, like maize, millet, wheat, and rice, can result in nutritional deficiencies, leading to various health issues.

Anemia

Iron deficiency anemia causes expansion of blood-forming tissues, leading to porotic hyperostosis (porous bone) on the skull.
Increased prevalence of porotic hyperostosis in agricultural settings suggests reduced dietary iron availability and potential intestinal parasite infections.

Growth Disruption

Reduced growth rate of children, measured by bone length, can lead to stunted growth and reduced adult height.
Stature can rebound depending on the timing and severity of the stressor.
Causes include malnutrition and various stressors.

Enamel Defects

Linear enamel hypoplasia is a defect in enamel formation, indicating growth disruption during childhood.
Caused by various stressors, including nutritional deficiencies and disease.

Animal Domestication

A co-evolutionary process where humans actively manage the survival and reproduction of another species, resulting in mutual benefits.
Domesticated animals provide humans with resources and services, including meat, milk, labor, transportation, and hunting assistance.

Domestication Process

Involves taming wild animals, assembling and managing groups, selective breeding for desirable traits, and integration into human society.

Evidence of Domestication

Animal demography in archaeological sites: The presence of young animals suggests domestication or raising of animals.
Morphological changes: Selective breeding leads to physical changes in domesticated animals, which are often smaller than their wild counterparts.
Genetic changes: aDNA analysis reveals genetic changes associated with domestication, including traits like temperament and fur color.
Paleopathology: Evidence of animal use can be found in skeletal remains.
