The Eastern Agricultural Complex & The Adena

This episode of "The Poor Proles Almanac" focuses on the Adena, an ancient Indigenous society that flourished in the Ohio River Valley region of North America around 3,000 years ago. The hosts, Andy and Elliott, discuss the Adena's unique burial practices, their role in the Eastern Agricultural Complex (EAC), and the insights their story offers into sustainable food systems and social organization.

A Society Defined by Monumental Burials and Egalitarian Principles: The Adena are best known for their distinctive earthen burial mounds, which served not only as graves but also as monumental structures that reflected their worldview and social bonds. These mounds, often aligned with astronomical events, suggest a sophisticated understanding of the cosmos and a commitment to communal labor and ritual practices.

Despite the complexity of these constructions, there is no evidence of a hierarchical social structure within Adena society. The hosts explore the concept of heterarchy, a system where leadership is fluid and situational, based on individual skills and circumstances rather than inherited power or status. Individuals gained temporary authority based on their expertise and accountability to the group, with power shifting and evolving over time. This system ensured that no one individual or group could hold power indefinitely, promoting a more egalitarian and adaptable society.

The Adena and the Dawn of Agriculture in Eastern North America: The episode places the Adena within the context of the Eastern Agricultural Complex (EAC), a significant center of early plant domestication in North America. The hosts emphasize that the Adena were not simply passive recipients of domesticated crops but actively participated in the process of selecting and cultivating plants that thrived in their region.

Hickory Nuts to Seeds: A Dietary Shift and its Implications: Archaeological evidence reveals a gradual shift in the Adena diet from a reliance on hickory nuts to a more diverse mix of seeds, particularly maygrass. This transition, occurring around 1,000 years ago, coincided with the introduction of corn to the region. Interestingly, corn did not immediately become a staple crop, taking another thousand years to adapt to the northern climate and dominate Adena agriculture. The hosts speculate on the reasons for this dietary shift, considering factors like changing forest composition due to anthropogenic fire, the potential advantages of seed-based crops, and the evolving relationship between the Adena and their environment.

Domestication Through Observation and Environmental Manipulation: The episode provides a detailed look at the domestication process, using erect knotweed as an example. This plant naturally produces two seed types: smooth seeds with thin coats that germinate quickly and rough seeds with thicker coats that can survive longer in the seed bank. The hosts explain how the Adena likely observed these traits and, through careful seed selection and the creation of favorable growing conditions, encouraged the dominance of the smooth, faster-growing variety. By understanding the plant's natural adaptations and manipulating their environment, the Adena were able to accelerate the domestication process, potentially reducing the time frame from a thousand years to a few hundred.

The Role of Bison and Fire in Shaping the Landscape: The episode introduces the concept of "anthropogenic niches" – ecosystems shaped by human activities. The hosts explain how the Adena, through controlled burning practices, created favorable conditions for fire-tolerant species like black walnut trees, which thrived in the disturbed soils along riverbanks. They also discuss the impact of bison, highlighting recent research that suggests these animals played a significant role in creating early successional habitats where the progenitors of many EAC crops flourished. The presence of bison, along with anthropogenic fire and floodplains, contributed to a dynamic and diverse landscape that supported the Adena's agricultural practices.

Rewilding and the Legacy of the Adena: The episode concludes with a reflection on the implications of the Adena story for contemporary discussions about rewilding and sustainable land management. The hosts acknowledge the complexity of these issues, raising questions about what constitutes an "original" ecosystem and whether the eventual decline of the Adena society diminishes the value of their practices. They emphasize the importance of learning from the past and recognizing that human societies and ecosystems are constantly evolving, urging listeners to consider the long-term ecological and social impacts of our actions.
