Environmental Determinism

The theoretical perspective asserting that the natural environment an individual or group lives in actively shapes their culture, art, and religious practices.

Subsistence Systems

The strategies, practices, and technologies through which human societies acquire food and sustain their populations.

Food Collection

The subsistence strategy of acquiring wild resources directly from the environment through foraging, hunting, or fishing rather than through cultivating crops or managing livestock.

Food Production

The intentional cultivation of domesticated botanical crops and the husbandry of domesticated animals to supply community nutrition.

Domestication

A sustained, multi-generational state of interdependence between humans and selected plant or animal species, artificially altering them to yield desirable traits.

Residue Analysis

The chemical examination of minute microscopic remnants—such as lipids, proteins, or bloodstains—preserved on archaeological tools or pottery vessels to identify their contents and use.

Isotope Analysis

The measurement of stable isotopic variations preserved in skeletal bone collagen, bioapatite, or tooth enamel to reconstruct ancient diets, environmental conditions, and geographic mobility.

Coprolite Analysis

The archaeological study of fossilized or desiccated ancient fecal material to identify dietary components, parasites, and local environmental proxies.

Shifts in global or regional climatic systems driven entirely by non-anthropogenic processes, such as major volcanic eruptions or cyclical variations in Earth's orbit.

Cultural Climate Change

Modifications to local or global climate patterns resulting directly from intentional or systemic human behaviors, such as extensive land clearing, deforestation, and agriculture.

Beringia

The subaerial land mass that connected Siberia and Alaska during periods of reduced Ice Age sea levels, serving as a primary corridor for human dispersal into the Americas.

The Saharan Neolithic

A period during which northern Africa experienced significantly more humid environmental conditions, supporting aquatic fauna such as hippopotamuses and catfish alongside pastoral communities.

Foraminifera

Minute marine protists that construct carbonate shells, which settle into seabed sedimentary deposits and preserve oxygen isotope ratios reflecting ocean temperatures and continental ice volumes.

Polar Ice Deposition

The stratified accumulation and compaction of seasonal snowfall across polar sheets over millennia, creating vertical climate archives sampled through ice cores.

Paleobotany

The archaeological and paleontological subdiscipline dedicated to the recovery and analysis of ancient plant remains to reconstruct past environments and human subsistence.

Macrobotanicals

Vegetative remnants preserved in archaeological contexts that are visible without high-powered magnification, such as charred seeds, nutshells, and charcoal fragments.

Microbotanicals

Microscopic botanical fossils recovered from sediment matrices or artifact surfaces, including pollen grains and phytoliths.

Pollen Grains

Microscopic reproductive units generated by seed-bearing plants that possess durable outer walls and exhibit species-specific morphology used to reconstruct regional flora.

Phytoliths

Durable microscopic silica bodies that precipitate within plant cells and persist in sediments after organic decomposition; typical of siliceous grasses.

Zooarchaeology

The systematic study of faunal skeletal remnants recovered from archaeological sites to elucidate past human-animal interactions, hunting strategies, and paleoenvironments.

Macrofauna

Animal specimens in the faunal assemblage with live body weights of $20\,\text{lbs}$ or greater, typically targeted by past peoples for meat, hides, and marrow.

Microfauna

Small animal remains weighing less than $20\,\text{lbs}$, such as rodents, small fish, and songbirds, which serve as sensitive indicators of local climatic and ecological changes.

Megafauna Overkill Hypothesis

The proposition that post-Pleistocene big-game extinctions occurring around $13{,}000$ years ago were caused primarily by human hunting, though climate-driven factors remain the prevailing scientific model.

Core

A prepared lithic mass or nodule from which usable sharp flakes or blades are systematically struck during flintknapping.

Hammerstone

A hard, unworked stone nodule used as an impact tool to detach flakes from a core or shape other lithic implements.

Flake

A sharp-edged lithic spall detached from a parent stone core through percussive force or applied pressure.

Conchoidal Fracture

The smooth, curved breakage pattern characteristic of microcrystalline and amorphous minerals like chert, flint, and obsidian when subjected to mechanical force.

Ground Stone Tools

Implements produced through the labor-intensive techniques of pecking, abrasion, and grinding using tough, crystalline rocks such as granite, basalt, or limestone.

Mano

A handheld ground stone cobble moved back and forth or rocked against a lower stationary slab to crush and process grain.

Metate

A large, stationary stone base possessing a flat or concave grinding trough upon which dried grains are ground with a mano.

Temper

Non-plastic materials intentionally incorporated into wet clay bodies to reduce shrinkage, prevent thermal shock, and minimize cracking during firing.

Grog Temper

Crushed, pre-fired ceramic sherds ground into uniform grit and mixed into fresh clay to function as an opening material.

Slip

A liquid suspension of fine clay particles in water painted over an unfired ceramic vessel to alter surface coloration and prepare it for decoration.

Glaze

A silica-rich vitreous coating applied to ceramics and fused at high kiln temperatures to create a non-porous, glossy finish.

Pit Firing

A direct pottery firing method in which vessels are placed into an open pit with combustible biomass and fired without a permanent architectural structure.

Metallurgy

The technological sequence involving the extraction of metallic elements from natural ores, followed by refining, casting, and alloying into utilitarian or prestige goods.

Smelting

The pyrotechnological process of heating metallic ores to their reduction temperature to melt and separate the base elemental metal from rocky slag impurities.

Alloying

The deliberate combination of two or more molten metals to produce a secondary material with superior mechanical properties, such as fusing copper with tin to produce bronze.

Bronze

A composite metal alloy classically formulated from $90\%$ copper and $10\%$ tin or arsenic.

Macahuitl

A composite Mesoamerican close-combat club crafted from carved dense wood and inset along its perimeter with razor-sharp prismatic obsidian blades.

Balanced Reciprocity

An exchange mode involving a direct transfer of commodities or services between social equals with an expectation of an equivalent return within a defined interval.

Positive Reciprocity

An exchange transaction characterized by unilateral generosity, wherein an individual or faction yields vast wealth with nominal immediate reciprocation, such as during a potlatch.

Negative Reciprocity

An economic interaction in which a party attempts to maximize their personal acquisition while minimizing their outward expenditure or return.

Redistribution

An economic mechanism whereby surplus goods or tribute are surrendered by a population to a central authority, who subsequently reallocates them.
