A man buried in Russia in the Early Bronze Age era
The Afanasievo culture, existing from approximately 3500 to 2500 BCE, represents one of the early manifestations of the Indo-European cultural and linguistic family. It played a crucial role in shaping the prehistoric landscape across parts of what is now southern Siberia and Central Asia. Named after the village of Afanasievo in the Russian Altai Mountains where the first archaeological findings were gathered, this culture provides a fascinating glimpse into the lives of one of the earliest groups to spread Indo-European languages.
Geographical and Chronological Context: The Afanasievo culture appeared in the Altai-Sayan region, spanning across southern Siberia into Mongolia and the foothills of the Altai Mountains. This culture emerged during the Bronze Age, sharing temporal proximity with other significant early European cultures, such as the Yamnaya on the western steppes.
Archaeological Characteristics: The Afanasievo people are primarily known through their burial sites, which display rich mortuary practices. Burials were typically conducted in rectangular pits with stone coverings, and the dead were often laid on their backs, sometimes interred with personal belongings and cattle remains. These practices suggest a community deeply reliant on livestock and indicative of a pastoral lifestyle, a hallmark of many Proto-Indo-European societies.
Material Culture and Technology: The material culture of the Afanasievo is characterized by distinctive pottery, which includes flat-bottomed jars, often embellished with geometric patterns. Stone was the primary material for tool-making, including polished axe heads and other implements. There is also evidence of basic metallurgy, with copper items having been recovered, signaling an early transition from the Stone Age toward more advanced metal use.
Economy and Subsistence: The Afanasievo people were primarily pastoralists, herding cattle, sheep, and goats. This aligns with the economic patterns of many Steppe cultures, supporting a semi-nomadic lifestyle with elements of settled pastoralism. The presence of domesticated animals, particularly horses, suggests a culture adept in animal husbandry and potentially the early use of horses in transport and communication.
Cultural and Linguistic Significance: One of the most compelling aspects of the Afanasievo culture is its possible connection to the broader spread of Indo-European languages. The similarities between Afanasievo and cultures like Yamnaya, especially in burial practices and economic structures, support theories that the Afanasievo culture might have played a role in the eastern expansion of Indo-European peoples. This connection is crucial for understanding the prehistoric dissemination and development of Indo-European languages across Eurasia.
Interactions and Legacy: While the Afanasievo culture thrived, it likely interacted with neighboring cultures, influencing and being influenced by them. Its eventual overlap with the Okunev culture suggests a period of cultural transition or amalgamation. The precise nature of these interactions remains a subject of archaeological investigation, but they underscore the dynamic nature of cultural exchange in prehistoric times.
In summary, the Afanasievo culture is a pivotal chapter in the prehistoric narrative of Eurasia, offering insights into the early movements and influences of Indo-European groups across the vast steppes. Its legacy is visible in the continuities observed in subsequent regional developments as well as its contributions to the historical tapestry that has shaped modern linguistic and cultural landscapes.
Ancient genetic admixture analysis compares the DNA profile of this individual (I6714) 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 (I6714) 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.

A unified genealogy of modern and ancient genomes
The sequencing of modern and ancient genomes from around the world has revolutionized our understanding of human history and evolution. However, the problem of how best to characterize ancestral relationships from the totality of human genomic variation remains unsolved. Here, we address this challenge with nonparametric methods that enable us to infer a unified genealogy of modern and ancient humans. This compact representation of multiple datasets explores the challenges of missing and erroneous data and uses ancient samples to constrain and date relationships. We demonstrate the power of the method to recover relationships between individuals and populations as well as to identify descendants of ancient samples. Finally, we introduce a simple nonparametric estimator of the geographical location of ancestors that recapitulates key events in human history.
