CORE DEFINITION

Finches on the Galápagos Islands with diverse beak shapes, which inspired Darwin to propose the theory of natural selection.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Homologous 'variants' adapted to different environments can reveal evolutionary mechanisms.

anchor

Anchor fast decisions

Homologous populations undergo adaptive radiation due to environmental differences, with beak shape differentiation corresponding to different food niches, serving as empirical evidence for natural selection.

RELATED MODELS

Related model

Exaptation

A trait originally evolved or invented for one function is later co-opted to serve a completely new function. Gould and Vrba coined the term in 1982 to replace the teleological "pre-adaptation".

Semelparity

Semelparity and iteroparity are two reproductive strategies available to living organisms. A species is semelparous if it is characterized by a single reproductive episode before death, and iteroparous if it is characterized by multiple reproductive cycles.

The Anna Karenina Principle

For tasks requiring several necessary conditions jointly, failure of any one may prevent success; this does not make all successful cases identical.
