Lesson Notes

Archaeology is the scientific study of human history and prehistory through the excavation, analysis, and interpretation of material remains such as artifacts, architecture, biofacts, and cultural landscapes. Unlike history, which relies primarily on written records, archaeology reconstructs the human past by examining the physical evidence that people left behind, making it uniquely capable of illuminating periods and cultures for which no written sources exist. The discipline spans from the earliest stone tools crafted by hominins over three million years ago to the material culture of modern industrial societies, providing an unbroken window into the full arc of human experience.

The methods of archaeology are both rigorously scientific and deeply interpretive. Fieldwork techniques such as systematic survey, stratigraphic excavation, and remote sensing are used to locate and recover evidence in context, while laboratory analyses including radiocarbon dating, ceramic typology, zooarchaeology, and ancient DNA extraction help researchers determine the age, origin, function, and significance of finds. The principle of stratigraphy, borrowed from geology, is foundational: layers of soil and debris accumulate over time, and earlier deposits lie beneath later ones, allowing archaeologists to reconstruct chronological sequences of human activity at a site.

Today, archaeology intersects with numerous other disciplines including anthropology, history, geology, chemistry, biology, and computer science. Subfields such as underwater archaeology, industrial archaeology, forensic archaeology, and landscape archaeology reflect the breadth of its applications. The discipline also grapples with critical ethical questions about the ownership of cultural heritage, the repatriation of artifacts to descendant communities, the impact of looting and illicit antiquities trade, and the responsibilities that come with interpreting and representing the pasts of marginalized peoples.

You'll be able to:

Identify the methods archaeologists use to locate, excavate, and date material remains of past societies
Apply stratigraphic analysis and artifact typology to reconstruct chronological sequences at archaeological sites
Analyze material culture evidence to interpret subsistence strategies, social organization, and belief systems
Evaluate competing archaeological interpretations by assessing the strength of evidence and theoretical frameworks used

One step at a time.

Key Concepts

Stratigraphy

The study of rock and soil layers (strata) used to determine the relative chronological sequence of deposits at an archaeological site. Based on the law of superposition, undisturbed lower layers are older than those above them, providing a framework for understanding when events occurred.

Example: At a tell site in the Near East, an archaeologist identifies twenty distinct occupation layers, with the deepest containing Neolithic pottery and the uppermost holding Ottoman-period coins, allowing reconstruction of thousands of years of settlement history.

Radiocarbon Dating

A radiometric dating method that measures the decay of carbon-14 in organic materials to estimate their age, effective for samples up to roughly 50,000 years old. It revolutionized archaeology by providing the first reliable means of obtaining absolute dates for prehistoric contexts.

Example: Charcoal recovered from a hearth at a Paleolithic cave site is submitted for radiocarbon dating and returns a calibrated date of approximately 32,000 years before present, confirming the site's Upper Paleolithic occupation.

Excavation

The systematic removal and recording of soil and artifacts from an archaeological site, conducted in controlled units and stratigraphic layers. Because excavation is inherently destructive, meticulous documentation through photographs, drawings, and digital recording is essential to preserve the contextual information.

Example: A team excavates a Roman villa in Britain using a grid of one-meter squares, carefully troweling through each context, screening soil for small finds, and recording the exact three-dimensional position of every artifact.

Artifact Typology

The classification of artifacts into types based on shared attributes such as form, material, decoration, and manufacturing technique. Typological sequences allow archaeologists to date sites by comparing their assemblages to established chronological frameworks.

Example: A lithics specialist classifies a collection of stone tools from a French cave into Mousterian, Aurignacian, and Magdalenian types, each associated with different periods and hominin populations.

Cultural Resource Management

The branch of archaeology concerned with identifying, evaluating, and protecting archaeological sites threatened by development, construction, or natural processes. CRM work constitutes the majority of professional archaeological practice in many countries and is governed by heritage protection laws.

Example: Before a new highway is built in the United States, a CRM firm conducts a Phase I survey of the route, discovers a pre-contact Native American village site, and recommends either avoidance or full excavation before construction proceeds.

Ethnoarchaeology

The study of living or historically documented cultures to develop analogies and interpretive models for understanding archaeological remains. By observing how contemporary people make, use, and discard material objects, ethnoarchaeologists generate hypotheses about past behavior.

Example: A researcher lives with semi-nomadic herders in East Africa to document how they construct and abandon campsites, then uses those observations to interpret similar patterns found at prehistoric sites in the same region.

Remote Sensing

Non-invasive techniques used to detect buried archaeological features without excavation, including aerial photography, satellite imagery, ground-penetrating radar, magnetometry, and LiDAR. These methods allow large-area survey and site discovery while minimizing physical disturbance.

Example: LiDAR scanning of dense jungle in Guatemala reveals an extensive network of previously unknown Maya causeways, reservoirs, and pyramid complexes hidden beneath the forest canopy.

Seriation

A relative dating technique that arranges artifacts or assemblages in chronological order based on the frequency of stylistic attributes, assuming that styles follow a predictable pattern of introduction, peak popularity, and decline. It is especially useful when absolute dating methods are unavailable.

Example: By analyzing the changing frequencies of painted pottery designs across multiple burial sites in the American Southwest, an archaeologist establishes a relative chronological sequence for Ancestral Puebloan communities.
