A woman buried in Portugal in the Late Neolithic to Copper Age era
The Late Neolithic to Chalcolithic period in Portugal marks a fascinating era in the evolution of Western European prehistoric societies, characterized by significant cultural, technological, and social developments. This period, roughly spanning from 3000 to 2000 BCE, is pivotal in the prehistoric timeline as it encompasses the transition from hunter-gatherer communities to more settled agricultural societies, alongside the introduction and development of metalworking technologies.
Geography and Environment
Portugal's geography during this time featured a diverse landscape of coastal regions, rolling plains, river valleys, and mountainous areas. The temperate climate provided fertile lands that were well-suited for agriculture. The landscape played a critical role in shaping the cultural and economic activities of the period. Proximity to the Atlantic Ocean not only influenced subsistence strategies but also facilitated maritime interactions with other regions, contributing to cultural exchanges and trade.
Subsistence and Economy
During the Late Neolithic to Chalcolithic period, Portugal saw a shift towards more permanent settlements as agriculture became increasingly important. Communities engaged in mixed farming, cultivating crops such as wheat and barley and domesticating animals like sheep, goats, and cattle. This agricultural base was complemented by hunting, fishing, and gathering, which remained important for subsistence.
The introduction of metallurgy, particularly copper working, marked the Chalcolithic era, leading to economic and technological advancements. This period saw the production of tools, ornaments, and weapons, which played a role in enhancing agricultural productivity, trade, and social hierarchy.
Social Structure and Settlements
Settlements during this period ranged from small hamlets to larger fortified sites, indicating a degree of social complexity and organization. Megalithic architecture, such as large stone tombs (dolmens) and standing stones (menhirs), became prominent, reflecting both advanced engineering skills and the social and ceremonial importance of these structures. These monumental constructions suggest the presence of organized labor and possibly a class of specialized workers or artisans.
The society of this era likely had a hierarchical structure, with emerging social stratification linked to control over resources, trade, and technological knowledge. Leaders or elites may have played pivotal roles in coordinating labor for monumental building projects and managing trade networks.
Megalithic Culture and Rituals
The Late Neolithic to Chalcolithic period in Portugal is notably marked by its megalithic culture, part of a broader Western European phenomenon. The construction of megalithic monuments for burial and ceremonial purposes indicates a complex belief system and a strong connection to ancestor worship. Tombs were often oriented in specific ways, suggesting astronomical alignments, which points to the importance of celestial events in their ritual practices.
These megalithic sites served as focal points for community gatherings, rituals, and ceremonies, reinforcing social cohesion and cultural identity. The presence of grave goods in these sites reflects varied burial practices and the belief in an afterlife, indicating a sophisticated spiritual and religious outlook.
Art and Craftsmanship
Art and decorative crafts flourished during this period, with pottery becoming more sophisticated in design and function. Pottery styles evolved from simple geometric decorations to more complex shapes and motifs, potentially influenced by interactions with other regions. Stone tools continued to be refined, with the production of polished stone axes, arrowheads, and other implements.
The emergence of metalworking, particularly in copper, represented a significant technological advance. Metallurgy not only provided new materials for tools and ornaments but also fostered specialized skills and knowledge, giving rise to a class of craftspeople within the society.
Trade and Interaction
The period was marked by dynamic trade networks both within the Iberian Peninsula and with other regions in Western Europe. Exchange of goods such as pottery, metals, and exotic materials indicates a well-established system of trade and cultural interaction. Maritime travel and coastal trading routes facilitated these exchanges, making the Iberian Peninsula a crucial cultural and economic hub in prehistoric Europe.
Conclusion
The Late Neolithic to Chalcolithic era in Portugal represents a transformative period characterized by technological innovation, social complexity, and cultural richness. The megalithic monuments stand as enduring testaments to the ingenuity and spiritual life of these prehistoric communities. This era laid the groundwork for subsequent developments in the Bronze Age, influencing the trajectory of cultural evolution in the region. As archaeological research continues to unfold, our understanding of this vibrant period deepens, revealing a tapestry of human endeavor in prehistoric Portugal.
Ancient genetic admixture analysis compares the DNA profile of this individual (CovaMoura9B) 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 (CovaMoura9B) 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 population genomics of archaeological transition in west Iberia: Investigation of ancient substructure using imputation and haplotype-based methods
We analyse new genomic data (0.05-2.95x) from 14 ancient individuals from Portugal distributed from the Middle Neolithic (4200-3500 BC) to the Middle Bronze Age (1740-1430 BC) and impute genomewide diploid genotypes in these together with published ancient Eurasians. While discontinuity is evident in the transition to agriculture across the region, sensitive haplotype-based analyses suggest a significant degree of local hunter-gatherer contribution to later Iberian Neolithic populations. A more subtle genetic influx is also apparent in the Bronze Age, detectable from analyses including haplotype sharing with both ancient and modern genomes, D-statistics and Y-chromosome lineages. However, the limited nature of this introgression contrasts with the major Steppe migration turnovers within third Millennium northern Europe and echoes the survival of non-Indo-European language in Iberia. Changes in genomic estimates of individual height across Europe are also associated with these major cultural transitions, and ancestral components continue to correlate with modern differences in stature.
