    Study Notes

    Reconstructing the Past: How Did People Live?

    • Key topics include human remains and past diets, past environments and settlement patterns, and social systems and cultural change.

    Provenience

    • Archaeologists are deeply concerned with provenience, which refers to the location of artifacts or remains.

    The Archaeological Record's Incompleteness

    • The archaeological record is incomplete due to factors like preservation bias, floods, natural disasters, and the limited number of sites left to excavate.

    Palaeopathology

    • Palaeopathology is the study of diseases and disorders in past populations.
    • Examples include trauma (fractures), infectious diseases (leprosy), degenerative diseases (osteoarthritis), metabolic diseases (rickets), and dental pathology (caries).

    Approaches to Pathology Interpretation

    • Macroscopic analysis (visual examination);
    • Microscopic analysis (thin section bone);
    • Radiographic analysis (X-rays);
    • Chemical analysis (e.g., isotopes)

    Sword Wound Trauma

    • A sword wound, without signs of healing, suggests a possible cause of death.

    Trephination Trauma

    • Evidence of healing suggests trephination was done with a goal of treatment, rather than death.

    Metabolic Disease: Rickets

    • Rickets is a disturbance in bone formation in growing children that shows a characteristic bowing in the long bones, due to inadequate calcium and phosphorus deposition.

    • Causes: Vitamin D deficiency resulting from inadequate calcium absorption in the intestine.

    • Vitamin D is produced when skin is exposed to UV rays.

    • Another source is within certain fatty fish.

    • Increased risk during the Industrial Revolution due to poor diets, lack of sunlight, and industrial smog.

    • Another risk is environmental factor of low UV exposure in northern latitudes and social customs.

    Bone Qualities

    • Bone is living tissue reacting to environmental factors like stressors over a lifetime.
    • Bone changes are usually associated with chronic conditions compared to acute ones.

    Bone Use Limitations

    • Diagnosis cannot be made based solely on symptoms.
    • Not every disease affects the bones.
    • Manifestations of the same disease can vary between different people.
    • Modern knowledge is helpful but some diseases and evolution can alter the way they manifest themselves in skeletal remains.

    The Case of: Harris Lines

    • Harris lines are visible as increased density in radiographs of long bones, especially the distal tibia.
    • They indicate a resumption of growth after a period of growth arrest.
    • They can be non-specific stress indicators that reflect nutritional problems, illness or emotional factors during childhood.

    Another Complication: "Pseudopathology"

    •  Pseudopathology is the appearance of bone pathology due to mechanical forces (e.g., weight of earth), chemical erosion, or living/animal agents (like plants or gnawing).
    • Excavation hazards also cause such complications in the skeletal record.

    "Palaeodemography"

    •  Palaeodemography is the study of population dynamics through examining population age and sex structure, population growth, fertility and mortality.
    • "Cause-specific mortality" can be aided by understanding palaeopathology.

    "Palaeonutrition"

    • Palaeonutrition reconstructs past diets.

    Evidence: Ancient Subsistence

    • Evidence comes from environmental data, like flora and fauna, artifacts (tools, weapons, cooking vessels, killing materials and plow blades), plant remains, faunal remains, and coprolites (fossilized faeces).

    Stable Isotopes & Trace Elements

    • Stable isotope and trace element analysis directly analyze human bone to ascertain past diet due to the principle that "You are what you eat."

    Stable Isotope Analysis

    • Bone and hair samples provide an isotopic profile to track isotopes, including carbon-12, carbon-13 and nitrogen-15, offering insight into diet variability.

    Carbon Isotopes

    • Photosynthetic pathways of plants are crucial.
    • C4 plants (tropical/subtropical) have a higher carbon-13 ratio and C3 plants have a higher carbon-12 ratio.
    • Ratios provide information on the relative quantities of C3 and C4 plants in the diet.

    Nitrogen Isotopes

    • Ratios of nitrogen isotopes reveal the relative position of individuals on the food chain (herbivore, omnivore, carnivore).
    • Higher nitrogen-15 levels suggest a higher position in the food chain.
    • The presence of higher nitrogen-15 levels in babies' tissues indicates breast milk consumption.

    Trace Elements: Strontium

    • Evidence of different trace elements in bone can provide further detail on diet and subsistence patterns.
    • Examples include strontium, showing relative levels of herbivores, omnivores, and carnivores.

    History of Evolutionary Theory

    • Pre-Darwinian views considered a static world, design, and typological thinking.
    • Darwinian thinking emphasized population evolution and variation as fundamental concepts.

    Evolution

    • Evolution is a systematic change through time.
    • Organisms evolve biologically and socially/culturally.
    • Modern species are a consequence of prior forms.

    Essentialism

    • Essentialism is a concept in pre-Darwinian views where all living organisms were perceived as fixed forms, and individual variation wasn't considered significant.

    Great Chain of Being

    • The Great Chain of Being is a pre-Darwinian conceptual framework ranking organisms based on a strict hierarchy, with humans viewed towards the divine.
