The Extended Phenotype
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
The phenotype of a gene should not be limited to the biological individual's body (such as blue eyes, long legs), but should extend to the organism's influence on the environment. - Examples: beaver dams, spider webs, parasites altering host behavior. These external artifacts are also part of the gene's 'body'. -
SCAFFOLDING EFFECT
Reduce cognitive load
Redefinition of capability boundaries. - For humans, mobile phones, cars, AI tools, and even the companies you manage are your 'extended phenotype'. Your capabilities depend not only on your brain (biological body), but also on your ability to build and control external systems (extended phenotype).
Anchor fast decisions
The extended phenotype refers to genes not only shaping the body, but also altering the external world (nests, dams, culture) through behavior as an extension of their own replication. It pushes the boundary of 'phenotype' beyond the organism.
