CORE DEFINITION

A trait that originally evolved for one purpose is later co-opted for a completely different function. (For example, feathers originally evolved for warmth, later co-opted for flight).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Cross-domain innovation. Examine your existing assets (technology, channels, data) and ask yourself: "What completely unrelated problem can this solve besides its current use?" Great innovations often arise from the misuse of old functions.

Anchor fast decisions

Proposed by paleontologists Stephen Jay Gould and Elizabeth Vrba: a trait evolves for function A, then is 'co-opted' for an unrelated function B (feathers first for warmth, then for flight; bones first for support, then for auditory ossicles). The core is 'existing features are given new uses in new contexts', which is an important source of innovation—not necessarily inventing from scratch, but often old things used in new ways.

First Principles

In philosophy and science, a first principle (or first principles) refers to a basic proposition that cannot be deduced from any other proposition or assumption. The concept originates in philosophy from Aristotle's doctrine of the 'first cause', while in Kantian philosophy, its corresponding form is called a 'postulate'. In mathematics and formal logic, first principles manifest as 'axioms' or 'postulates', constituting the absolute starting point of logical deduction. In physics and other scientific fields, if the research process is entirely based on fundamental physical laws, without relying on empirical models or parameter fitting, it is referred to as 'from first principles' or 'ab initio'.
