# Niche Construction > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] connects this node to the substrate-independent history of heredity, selection and computational populations. **Domain:** Evolution / Ecology / Human-Machine Systems **Doc Type:** Canonical Concept Node **Maturity:** Foundational ## Definition **Niche construction** is the process by which organisms modify environmental conditions and thereby alter selection pressures affecting themselves, descendants and other organisms. ## Human and Machine Context Human agriculture, cities, medicine, institutions and media are intensified niche construction. They change mortality, reproduction, learning and social selection. [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] argues that computing continues this lineage by exteriorizing memory, inference and increasingly the environment in which cognition develops. [[articles/Escape Hatch in the Skull|Fuck the Environment: We're Building an Escape Hatch in the Skull]] makes this connection explicit and carries niche construction to its transhuman endpoint: humans are adapted not merely to environments but to **[[wiki/Environmental Replacement|replacing them]]**. Clothing, shelter, agriculture, cities and networks are successive counter-environments; neural interfaces mark the point at which niche construction crosses the skin and begins constructing the receiving habitat of cognition itself. At that boundary, environment and cognitive architecture become difficult to separate. The receiving substrate is not passive: it selects what can be represented, remembered and acted upon. ## Governance Context Niche construction distributes power across generations. Designers create environments future subjects cannot choose before entering. This creates duties of reversibility, pluralism, access and protection against lock-in. ## Key Insight **Intelligence does not merely adapt to an environment; it increasingly inherits environments built by prior intelligence and becomes responsible for the selection pressures it creates.** ## Sources / Provenance - Odling-Smee, Laland and Feldman, _Niche Construction_, 2003. - Marcus Feldman publication profile: https://profiles.stanford.edu/marcus-feldman ## See Also [[wiki/Human Ecology|Human Ecology]], [[wiki/Environmental Replacement|Environmental Replacement]], [[wiki/Cognitive Exteriorization|Cognitive Exteriorization]], [[wiki/Co-Creative Substrate|Co-Creative Substrate]], [[wiki/Transition Architecture|Transition Architecture]], [[articles/Escape Hatch in the Skull|Escape Hatch in the Skull]]
