The Chalcolithic period, also known as the Copper Age, represents a transitional phase between the Neolithic (New Stone Age) and the Bronze Age, characterized by the first use of metal tools and weapons. In Iberian Chalcolithic or Chalcolithic Spain, this era is particularly significant as it marks a period of social, technological, and cultural transformation that laid the groundwork for subsequent developments in the Iberian Peninsula.

Chronology and Geography

The Chalcolithic period in the Iberian Peninsula roughly spans from 3000 to 1800 BCE, although the exact dates may vary regionally due to the diversity of cultural developments across the area. The Iberian Chalcolithic culture was widespread across modern-day Spain and Portugal, with notable concentrations in regions such as Andalusia, Extremadura, and central and eastern parts of the peninsula.

Technological Innovations

The hallmark of the Chalcolithic period is the emergence of metalworking, particularly with copper. While stone tools continued to be predominant for numerous functions, the advent of metalwork introduced new tool types, such as axes, blades, and ornaments, indicating both utilitarian and ceremonial uses. The knowledge of metallurgy, although initially basic, laid important foundations for the subsequent Bronze Age.

Settlements and Architecture

Settlements during the Iberian Chalcolithic period became more complex, with a mix of small hamlets, larger fortified villages, and even the first proto-urban centers. One of the most notable sites is Los Millares in Almería, southern Spain, characterized by its impressive fortifications, multiple concentric walls, and complex, densely packed houses. This site, along with others like Vila Nova de São Pedro in Portugal, showcases advanced organizational and construction skills, reflecting emerging social hierarchies.

Social Structure

The Chalcolithic era is marked by increasing social stratification. This is evidenced by the differentiation in grave goods found in burial sites, suggesting a society with distinct social classes and roles. The appearance of megalithic tombs and the prevalence of grave goods indicate the importance of social status, and possibly the emergence of a priestly or ruling class that wielded both religious and secular power.

Economy and Subsistence

Agriculture continued to evolve with a mixed economy of farming and herding. Crops such as barley, wheat, and legumes were commonly cultivated, while the domestication of animals, including cattle, sheep, and goats, remained integral. The Chalcolithic economy also saw an expansion in trade networks, as evidenced by the distribution of exotic materials like amber and ivory, indicating far-reaching contacts across Europe and the Mediterranean.

Cultural and Ritual Practices

Chalcolithic Spain is noted for its rich cultural and ritualistic life. The construction of large megalithic monuments, such as dolmens and menhirs, points to sophisticated ceremonial practices possibly related to ancestor worship or cosmology. Art from this period includes pottery with intricate designs and engravings on rock surfaces, hinting at symbolic or narrative expressions.

Challenges and Declines

The end of the Chalcolithic period saw several challenges that may have precipitated changes leading into the Bronze Age. Environmental changes, resource depletion, and social tensions within increasingly stratified societies could have led to competition and conflict, catalyzing further societal transformations.

Conclusion

The Iberian Chalcolithic era was a vibrant and dynamic period marked by significant advancements that would critically shape the trajectory of prehistoric Iberia. Its legacy is seen in the technological innovations, social complexity, and artistic expressions that laid a foundation for the subsequent cultural blossoming in the Bronze Age. This period remains a fascinating field of study for archaeologists and historians, offering insights into early European societies' adaptability and ingenuity.

Ancient genetic admixture analysis compares the DNA profile of this individual (ATP20) 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 (ATP20) 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 ATP20 are as follows. You can analyze its admixture using G25 Studio.
