A man buried in Chile in the Pre-Columbian South America era
The Selknam, often referred to as the Ona, were an indigenous people who inhabited the northern part of Tierra del Fuego in South America. This region, which is now part of modern-day Chile and Argentina, is characterized by harsh climatic conditions, including cold temperatures, strong winds, and rugged terrain. The mention of \100BP" (Before Present) suggests a focus on their culture as it might have existed around the early 20th century.
Social Structure and Lifestyle
The Selknam were traditionally semi-nomadic hunter-gatherers. Their social organization was structured around small, kin-based groups known as bands. Each band was relatively autonomous, consisting of a few families who moved seasonally to exploit different resources across their territory. These movements were guided by the availability of game and other necessities.
Economy and Subsistence:
- Hunting: The Selknam were skilled hunters and relied heavily on guanacos (a wild camelid), which provided them with food, clothing, and tools. Hunting was primarily a male activity, often involving elaborate strategies and the use of bows, arrows, and spears.
- Gathering: Women played a crucial role in gathering plant foods, such as berries, seeds, and roots, which supplemented their diet.
Tools and Technology:
Their tools were crafted mainly from stone, wood, and bone. They developed a range of implements for hunting, processing food, and making clothing. Their clothing, often made from guanaco hides, was designed to withstand the cold and windy climate.
Cultural Practices
The cultural and spiritual life of the Selknam was rich and complex, with many aspects woven into their daily activities and social interactions.
Spiritual Beliefs:
- Mythology and Cosmology: The Selknam had a deep connection to their land and its ecology, which was reflected in their myths and oral traditions. They believed in a pantheon of spirits and deities that governed natural and supernatural phenomena.
- Selknam Initiation Ritual (Hain): One of the most important cultural ceremonies was the Hain, a rite of passage for young men that involved elaborate body painting and costuming. This initiation was a dramatic expression of their mythology, involving stories and enactments that symbolized the universe's creation and the moral code of society.
Art and Body Adornment:
Body painting and adornment played a significant role in Selknam culture, particularly during rituals. They used natural pigments to create intricate designs on their bodies, each pattern holding specific meanings and serving to convey social and spiritual messages.
Language
The Selknam spoke the Selknam language, which is part of the Chonan language family. Like many indigenous languages, it was an essential part of their cultural identity and worldview, encapsulating their unique history, traditions, and relationship with their environment.
Impact of Colonization
By the early 20th century, the Selknam culture was in decline due to the onslaught of European colonization. The introduction of sheep farming and land claims by European settlers drastically disrupted their traditional lifestyle, leading to violent conflicts and a dramatic reduction in population.
Cultural Disruption:
- Diseases and Displacement: The Selknam, like many indigenous peoples, suffered from diseases brought by Europeans to which they had no immunity. Additionally, the encroachment of settlers led to displacement and loss of access to traditional hunting grounds.
- Marginalization and Assimilation: Many Selknam were forcibly assimilated or lived in marginal conditions compared to their traditional lifestyle. Christian missionary efforts also aimed to convert them and discourage indigenous practices.
Legacy
Today, the Selknam are often remembered through efforts to revitalize and preserve their cultural heritage. While the population and distinct lifestyle have largely diminished, their stories, myths, and artistic expressions continue to be significant to the cultural tapestry of Tierra del Fuego and the broader narrative of indigenous resilience and adaptation in the face of external pressures."
Ancient genetic admixture analysis compares the DNA profile of this individual (I8576) 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 (I8576) 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.

Ancient genomes in South Patagonia reveal population movements associated with technological shifts and geography
Archaeological research documents major technological shifts among people who have lived in the southern tip of South America (South Patagonia) during the last thirteen millennia, including the development of marine-based economies and changes in tools and raw materials. It has been proposed that movements of people spreading culture and technology propelled some of these shifts, but these hypotheses have not been tested with ancient DNA. Here we report genome-wide data from 20 ancient individuals, and co-analyze it with previously reported data. We reveal that immigration does not explain the appearance of marine adaptations in South Patagonia. We describe partial genetic continuity since ~6600 BP and two later gene flows correlated with technological changes: one between 4700-2000 BP that affected primarily marine-based groups, and a later one impacting all <2000 BP groups. From ~2200-1200 BP, mixture among neighbors resulted in a cline correlated to geographic ordering along the coast.
