A woman buried in Canada in the Pre-Columbian North America era

The Arctic Small Tool Tradition (ASTt) represents a pivotal era in the prehistory of Arctic North America, roughly dating from about 2500 BCE to 500 CE. The ASTt is primarily associated with the Paleo-Arctic Tradition, an archaeological classification that denotes one of the earliest cultural adaptations to the harsh environments of the Arctic region, particularly in what is now Northern Canada and parts of Alaska.
Geographic and Temporal Context
The ASTt spanned a vast geographic area that included the high Arctic regions of Alaska, the Canadian Arctic Archipelago, and parts of Greenland. Emerging around 2500 BCE, this tradition continued until approximately 500 CE, marking it as a significant cultural phase that bridged the gap between earlier Paleo-Indigenous groups and later cultures like the Dorset and Thule.
Cultural and Technological Characteristics
The ASTt is characterized by its distinctive small stone tool assemblage. These tools were finely crafted and included microblades, burins, and scrapers made from materials such as chert, quartz, and obsidian. The hallmark of the ASTt is its efficient toolkit designed for maximum versatility in hunting, processing, and fabricating other tools or clothing. This speaks to the adaptive strategies of small, highly mobile groups that relied on these tools for survival in the Arctic's challenging environments.
Tools and Technology
- Microblades: Small, razor-sharp blades used as insets in bone or antler handles.
- Burin-like tools: Used for engraving or carving hard materials.
- End scrapers and side scrapers: Essential for processing hides and other organic materials.
These tools underpin a subsistence strategy well-suited to the Arctic's seasonal cycles, focusing heavily on hunting sea mammals, caribou, and exploiting other marine resources.
Subsistence and Lifestyle
The people of the ASTt were predominantly hunter-gatherers, exhibiting a considerable degree of mobility throughout the Arctic landscape. Their subsistence practices were highly adapted to the seasonalities of Arctic life. During the winters, groups would hunt seals on the sea ice, while in the summers, they would focus on caribou and fishing. This cyclical movement would have facilitated both resource acquisition and social exchange, allowing groups to share information and goods across vast distances.
Housing and Settlement Patterns
Evidence suggests that ASTt groups lived in temporary, semi-subterranean structures, which provided insulation against the harsh Arctic climate. These dwellings were small and indicative of relatively small, kin-based groups living together. The seasonal movement is also evident in the archaeological record, where sites are often located near resources like animal migration paths or coastal areas advantageous for hunting sea mammals.
Social and Cultural Aspects
Although the harsh environment left little in terms of preserved organic material, the ASTt is marked by its continuity and adaptability. The social structure would have likely been organized around family or kinship groups, with a culture geared to share resources and knowledge critical for survival. The gradual shift and adaptation of these tools and technologies into subsequent cultures testify to a rich tradition of innovation and resilience.
Significance and Legacy
The ASTt is crucial for understanding the peopling of the North American Arctic. It represents an important cultural and technological bridge between the earliest Arctic inhabitants and the cultures that followed. The ASTt's influence is visible in subsequent traditions such as the Dorset and Thule, each of which would continue to adapt and thrive in the Arctic environment.
This tradition's adaptation strategies and technological innovations are invaluable to the archaeological narrative of human resilience and perseverance in one of the planet’s most extreme environments. The ASTt exemplifies how human populations can ingeniously adapt to even the most challenging habitats, weaving their cultural legacy into the broader story of humanity's expansion and survival.

Ancient genetic admixture analysis compares the DNA profile of this individual (LU-05) with present-day reference populations. These results show what percentage of the individual's genetic makeup resembles ancient populations from different geographic regions.
Modern genetic admixture analysis compares the DNA profile of this individual (LU-05) with present-day reference populations. These results show what percentage of the individual's genetic makeup resembles modern populations from different geographic regions.
These results complement the ancient ancestry components shown in the previous section, offering a different perspective on the individual's genetic profile by comparing it with modern reference populations rather than prehistoric ancestral groups.
The G25 coordinates for the sample LU-05 are as follows. You can analyze its admixture using G25 Studio.

Ancient human parallel lineages within North America contributed to a coastal expansion
Little is known regarding the first people to enter the Americas and their genetic legacy. Genomic analysis of the oldest human remains from the Americas showed a direct relationship between a Clovis-related ancestral population and all modern Central and South Americans as well as a deep split separating them from North Americans in Canada. We present 91 ancient human genomes from California and Southwestern Ontario and demonstrate the existence of two distinct ancestries in North America, which possibly split south of the ice sheets. A contribution from both of these ancestral populations is found in all modern Central and South Americans. The proportions of these two ancestries in ancient and modern populations are consistent with a coastal dispersal and multiple admixture events.
