evolutionary theory model of evolution scientific theory

The theory of punctuated equilibrium is an evolutionary model proposing that species remain relatively unchanged for long periods, interrupted by brief, rapid bursts of significant evolutionary change often associated with speciation events.

How this entity was disambiguated

This entity first appeared as the object of triple T4396161 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A. shifting balance theory
Shifting balance theory is an evolutionary framework proposed by Sewall Wright that explains how genetic drift, selection, and gene flow interact across subdivided populations to drive adaptive evolution.
B. The Causes of Evolution
The Causes of Evolution is a foundational 1932 book by geneticist J. B. S. Haldane that helped establish the modern synthesis by mathematically integrating Mendelian genetics with Darwinian natural selection.
C. modern evolutionary synthesis
Modern evolutionary synthesis is the 20th-century unification of Darwin’s theory of natural selection with Mendelian genetics, forming the foundational framework of modern evolutionary biology.
D. Evolution
"Evolution" is a film featuring actress Katharine Towne, known as one of her more prominent screen roles.
E. Evolution
"Evolution" is a 2001 studio album by the American R&B group Journey, showcasing a blend of rock and melodic ballads that helped define their classic sound.
