CORE DEFINITION

An individual's learning ability can influence the direction of evolution. If a species learns a new skill through learning (such as eating a certain fruit), natural selection will tend to favor genes that make it easier to learn this skill innately, eventually converting acquired skills into innate instincts.

SCAFFOLDING EFFECT

Reduce cognitive load

- Soft-hard transformation: Explains the interaction between culture and genes. Our current 'instincts' (such as language ability) may be the result of ancestors' 'hard learning' over millions of years being written into genes.

The Baldwin effect holds that individuals can cope with the environment through learning and behavioral plasticity; this ability to cope by learning first is retained by natural selection, and over time the related abilities become fixed into genes, an evolutionary substitute for acquired characteristics. It reconciles the acquired with the inherited.

MINIMUM ACTION

In progress 0/3

Practice this model in one real situation:

(Evolutionary theory, not a method) Explains how 'behavioral innovations are selected and genetically assimilated'
in analysis, distinguishes short-term plastic adaptation from long-term genetic change
used to understand culture-gene coevolution.
