Natural selectioncausesAdaptationEstablished
Natural selection causes adaptation.
Mechanism: Natural selection accumulates the variants that survive and reproduce best, producing adaptations over generations.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.

Check yourself
A quick check against a common misconception. Nothing is scored — picking the tempting-but-wrong answer just flags an idea worth revisiting.
Which statement is correct?
An animal adapts to its environment during its own lifetime and passes those changes on.
Adaptation happens across generations by selection on inherited variation. A muscle built up by exercise is not passed to offspring.
Look for: Learner describes evolution as individuals changing to fit their needs (Lamarckism).

An adaptation is a feature that helps a living thing survive and have young in its surroundings — thick fur for cold, sharp claws for hunting. Adaptations build up over many generations, not within one lifetime.
An adaptation is a heritable trait that raised the survival or reproduction of ancestors in a particular environment and so spread through natural selection. Adaptations are historical products of selection, not goal-directed responses by individuals.
Mental models at work here
Feedback loop
A loop where an effect feeds back to change its own cause. Reinforcing loops amplify change; balancing loops resist it.
Ask: does the result push the system further in the same direction, or pull it back?
Optimization
Searching a space of options for the best one under constraints — following a gradient of 'better' toward a maximum or minimum.
Ask: what is being maximised or minimised, and what limits the search? Beware settling in a 'local' best that isn't the global one.
Variation & selection
When many varying candidates are filtered by a criterion and the survivors are copied, the population adapts to the criterion over rounds — with no designer.
Look for three ingredients: variation, a selection pressure, and inheritance/copying. Together they design without a designer.
