Niche Construction
Organisms actively modify their environments, altering selection pressures on themselves and others.
An evolutionary framework arguing that organisms actively modify their own and others' environments, with these modifications altering selection pressures in ways that feed back into evolutionary trajectories. Beavers building dams, earthworms processing soil, and humans building cities all create what the framework's proponents call ecological inheritance — environmental modifications that persist across generations alongside genetic inheritance. The framework challenges the standard view of organisms as passive recipients of selection pressures and has gained traction within the broader Extended Evolutionary Synthesis movement, though it remains contested within mainstream evolutionary biology about how much explanatory weight ecological inheritance deserves.
Core components
- Genetic inheritance
- Ecological inheritance
- Niche construction (active environmental modification)
- Feedback to selection pressures
- Coupling of evolutionary and ecological dynamics
Primary use case
Evolutionary theory; ecology; cultural evolution; debates about the Extended Evolutionary Synthesis.
Common criticisms
- Disputed within mainstream evolutionary biology about whether it adds explanatory power beyond standard selection
- the boundary between ordinary phenotypic effects and 'true' niche construction is contested
- risk of reifying a phenomenon that is already implicit in standard accounts.
