In "Organism and Environment" in "Scientia", and in more popular form in the last chapter of "Biology as Ideology", Lewontin argued that while traditional Darwinism has portrayed the organism as a passive recipient of environmental influences, a correct understanding should emphasize the organism as an active constructor of its own environment. Niches are not pre-formed, empty receptacles into which organisms are inserted, but are defined and created by organisms. The organism-environment relationship is reciprocal and dialectical. M. W. Feldman and others have developed Lewontin's conception in more detailed models under the term niche construction.
