CORE DEFINITION

Darwin and Wallace are the co-discoverers of natural selection, with Darwin the principal theorist and On the Origin of Species his most famous work. For Darwin, selection is a long and complex process involving many causally interlinked components, and it requires heritable variation to be present in the population. It is a mechanism rather than a goal-seeking force, and it operates whenever its conditions are jointly met.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Decompose the mechanism: split change into variation, inheritance, and differential reproduction. - Drop teleology: replace adaptation for a purpose with a process that has no foresight. - Locate the level: state whether selection acts on genes, individuals, or groups.

Anchor fast decisions

Whenever heritable variation exists in a population and those variants make a difference to survival and reproduction, carriers of the more favorable variants leave more offspring. Over many generations the frequency of the favorable variants rises and the population changes. The process needs no purpose or foresight; it is the necessary consequence of variation, inheritance, and differential reproduction being satisfied together.
