Niche Construction
The ecological principle that organisms do not merely adapt to pre-existing environments — they modify the selective environments of themselves and other organisms, and the modifications then act as selective pressures on subsequent generations.
Niche construction, formalized by F. John Odling-Smee, Kevin Laland, and Marcus Feldman in their 2003 monograph, describes a recursive loop that standard Darwinian theory had treated as secondary. The beaver builds a dam. The dam creates a pond. The pond alters the water table, the soil chemistry, the species composition of the surrounding forest. The forest, altered, provides different materials for the next generation of dams. The beaver has constructed a niche—not just for itself but for hundreds of other species that depend on the pond ecosystem. Applied to technology, niche construction describes what every major human tool has done: written scripts, printing presses, smartphones, and now AI have each constructed cognitive environments that select for different capacities. The difference with AI is the speed.

The beaver is the canonical case. Segal's Orange Pill uses the beaver as a metaphor for the builder who redirects the river of intelligence. The ecological framework makes
