Email: ac.pldk@nnamffoht Author information ▼ Article notes ► Copyright and License information ► Go to: Abstract Humans use a variety of deliberate means to modify biologically rich environs in pursuit of resource stability and predictability. Empirical evidence suggests that ancient hunter-gatherer populations engineered ecological niches to enhance the productivity and availability of economically significant resources. An archaeological excavation of a 3800-year-old wetland garden in British Columbia, Canada, provides the first direct evidence of an engineered feature designed to facilitate wild plant food production among mid-to-late Holocene era complex fisher-hunter-gatherers of the Northwest Coast. This finding provides an example of environmental, economic, and sociopolitical coevolutionary relationships that are triggered when humans manipulate niche environs.
