Biological evolution occurs across generations.
Inherited characteristics of populations change over generations. This is observed and supported by multiple kinds of evidence.
Show me why
Evolution concerns populations across generations, rather than an individual deciding to change. Fossils, genetic comparisons and direct observations contribute evidence about evolutionary change.
A common misconception
A scientific theory is an explanatory framework, not merely an unsupported guess.
Where the limits are
The details and timing of particular evolutionary histories can be revised. This entry does not make a theological claim.
How we know
The National Academies explains how different fields of biology support descent with modification. Distinguish the occurrence of change from a proposed account of a particular lineage: the latter may retain substantial uncertainty.
What would change this conclusion?
Specific mechanisms or histories change with evidence; overturning population change itself would require explaining extensive observations that already document it.
