evolve

/ɪˈvɑːlv/·verb

to change gradually over time, developing from one form into another
Fig. 1 — A fish swims to the shallows, and where the water ends the silhouette that continues has stub legs and drags itself up the sand.
01Definition

To evolve is to change gradually into something different — species across generations, languages across centuries, a company or a plan across years. From Latin evolvere, 'to unroll', as a scroll is unrolled to reveal what was already written along it. Two things distinguish it from plain change: it is gradual, made of accumulated small steps rather than a single break, and it is not a promise of improvement. Systems can evolve into worse arrangements quite as easily; an organism can adapt within a lifetime, but evolving takes generations.

06TOEFL & IELTS

Biology passages in TOEFL use it constantly, but the figurative sense is the essay tool: 'the role of universities has evolved', 'a rapidly evolving industry' — both signal gradual, ongoing change without claiming progress. Prepositions carry the sense: evolve FROM an ancestor or earlier form, evolve INTO a later one, evolve OVER time. Second-syllable stress, ih-VOLV, but the noun shifts vowel and stress: ev-uh-LOO-shun. The verb is regular — evolved, evolving.

07Asked
What does it mean when something evolves?
To change gradually into a different form, step by accumulated step. The scene above stages the biological case as a single walk — fish, then stub legs on sand, then a proper walker, then a runner, each fading into the next mid-stride — but the everyday sense works the same way: a company, a style, or an argument evolves when it becomes something else without any single moment of transformation.
Is it 'evolve from' or 'evolve into'?
Both, pointing opposite ways. From names the earlier form or ancestor — 'birds evolved from theropod dinosaurs'. Into names the later one — 'the club evolved into a national charity'. Over time is the third companion phrase, and the verb stands alone happily: 'the plan evolved'. It is usually intransitive, but biology uses it transitively too — 'plants have evolved defences against grazing' is standard.
What is the difference between evolve and adapt?
Adapt usually describes an individual adjusting within its lifetime, reversibly; evolving happens across generations and changes the lineage itself. Biology does also use adapt for whole populations changing by evolution, so the contrast is a default rather than a rule.
Does evolve mean improve?
No — and assuming so is the commonest misreading. Evolution describes change in response to circumstances, not progress toward better: cave fish evolved away their eyes, and parasites have evolved by losing organs. In everyday use the word borrows a hopeful tone ('our service has evolved'), but the honest meaning is neutral, which is exactly why careful writers reach for it when improvement is not yet proven.
What is the noun form of evolve, and does it only mean Darwin?
Evolution — and it ranges far beyond biology: the evolution of language, of jazz, of the smartphone, of a legal doctrine. Evolutionary is the adjective, and 'evolutionary rather than revolutionary' is a stock phrase for change that arrives gradually. Note the sound shift: the verb is ih-VOLV, but the noun opens up to ev-uh-LOO-shun, moving both the stress and the first vowel.
Why does evolve share a root with volume?
From Latin evolvere, 'to unroll' — e- 'out' plus volvere 'to roll', the same root as revolve and volume, which was originally a rolled scroll. The image is a scroll being unrolled to show what was written further along, and it survives in the modern sense: an evolving situation is one whose next stretch is being revealed rather than announced.
