Definition

Niche construction is the modification of environmental conditions by organisms in ways that feed back on subsequent development and selection. Descendants can inherit a world partly reshaped by prior life as well as genes. The corpus uses earthworms, beavers, plants and humans to illustrate this reciprocal history, without requiring conscious design, beneficial outcomes or replacement of natural selection by a separate universal mechanism.

Explanation

RB1’s ecological example makes organisms contributors to the pressures their descendants face, rather than passive occupants of a fixed background. Its native Odling-Smee, Laland and Feldman route preserves the theoretical attribution. An inherited modified environment is therefore a distinct kind of continuity from inheritance of a DNA sequence.

RB2 develops the historical dimension through atmospheric oxygenation, changed soils, beaver hydrology and human planetary effects. These examples need not involve intentional anticipation of evolutionary results. Organism-driven change can alter what becomes viable even when no organism planned the resulting selective environment.

The broader framework retains Darwinian selection while describing the causal architecture as reciprocal. Environmental change can enable some lineages and foreclose others; the mechanism is not a guarantee that all participants benefit or that a constructed niche remains stable. AB’s distinction between cultural and biological inheritance also prevents purposeful cultural transmission from being treated as genetic transmission by another name.
