A man buried in Russia in the Pleistocene era
The Kostenki 12 site, part of the larger Kostenki archaeological complex, holds profound significance in the study of Paleolithic cultures in Eastern Europe. Located along the Don River in the Voronezh Oblast of Russia, the site is an epicenter for understanding the Upper Paleolithic era, particularly regarding the behaviors, lifestyles, and technologies of early Homo sapiens in this region.
Historical Context: Kostenki 12, along with other sites in the Kostenki-Borshchevo area, dates back to approximately 40,000 to 22,000 years ago. This timeline places it in the Gravettian period, which is characterized by distinct tool types and cultural practices. The Gravettian phase in this region corresponds with the arrival and establishment of anatomically modern humans (Homo sapiens), marking a rich period of human expansion and adaptation in Eurasia.
Archaeological Findings: The excavations at Kostenki 12 have unveiled a plethora of artifacts that shed light on the cultural and technological sophistication of its inhabitants. The site revealed extensive use of flint tools, including blades, scrapers, and burins. These tools indicate advanced techniques in stone knapping and suggest a well-developed tradition of tool production.
The site also includes various personal ornaments, such as perforated beads and pendants, which are often made from ivory or bone. These items imply symbolic behaviors and possibly social stratification within the community. Additionally, figurative art such as Venus figurines has been discovered, representing some of the earliest known attempts at sculpture and human representation.
Subsistence and Settlement Patterns: The Kostenki 12 site provides vital evidence about the subsistence strategies of its Paleolithic inhabitants. Analysis of faunal remains indicates a reliance on big game hunting, including mammoth, bison, and horse. These large animals were likely central to the diet and material culture, providing meat, hides, bone, and ivory for a variety of uses.
Settlement patterns suggest semi-permanent habitation structures, possibly indicative of both mobile and sedentary phases within these communities. The placement and orientation of hearths and associated debris suggest organized living spaces, indicating a degree of planning and social organization.
Climatic and Environmental Context: During the period when Kostenki 12 was occupied, the region experienced fluctuating climatic conditions, as this timeframe overlaps with the Last Glacial Period. The cold and variable climate necessitated significant adaptability from human populations, influencing their technological innovations and migratory behaviors.
Cultural Significance: Kostenki 12, as part of the Kostenki complex, offers crucial insights into the cultural and cognitive development of early Homo sapiens. The artifacts and ecofacts demonstrate a culture capable of harnessing its environment not merely for survival but also for social and symbolic expression. This site, therefore, provides a window into the emergence of complex cognitive and cultural traits that define modern human societies.
Interdisciplinary Research: Research efforts at Kostenki 12 comprise contributions from archaeology, paleoanthropology, and earth sciences, among others. Radiocarbon dating and stratigraphic analysis have been pivotal in constructing the chronological framework of the site. Moreover, studies in paleobotany and palynology have contributed to reconstructing the palaeoenvironment, offering context for human adaptation strategies.
In conclusion, the Kostenki 12 site is invaluable for understanding the Upper Paleolithic narrative in Eastern Europe, revealing a rich tapestry of human adaptation, culture, and interaction with the environment during a critical period of human history. Its contributions to the study of prehistoric human life continue to influence our comprehension of past human societies and their development.
Ancient genetic admixture analysis compares the DNA profile of this individual (Kostenki12) 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 (Kostenki12) 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 genetic history of Ice Age Europe
Modern humans arrived in Europe ~45,000 years ago, but little is known about their genetic composition before the start of farming ~8,500 years ago. Here we analyse genome-wide data from 51 Eurasians from ~45,000-7,000 years ago. Over this time, the proportion of Neanderthal DNA decreased from 3-6% to around 2%, consistent with natural selection against Neanderthal variants in modern humans. Whereas there is no evidence of the earliest modern humans in Europe contributing to the genetic composition of present-day Europeans, all individuals between ~37,000 and ~14,000 years ago descended from a single founder population which forms part of the ancestry of present-day Europeans. An ~35,000-year-old individual from northwest Europe represents an early branch of this founder population which was then displaced across a broad region, before reappearing in southwest Europe at the height of the last Ice Age ~19,000 years ago. During the major warming period after ~14,000 years ago, a genetic component related to present-day Near Easterners became widespread in Europe. These results document how population turnover and migration have been recurring themes of European prehistory.
