evolution
/ˌɛvəˈluːʃən/·noun·1620s (military tactical movements); biological sense 1852 (Herbert Spencer), Darwinian sense widespread by 1872·Established
Origin
From Latin evolutio, 'an unrolling of a scroll' (from ex- + volvere, 'to roll,' PIE *wel-), the word shifted through military manoeuvres and embryology before Darwin reluctantly adopted it for species change — a term he avoided in favour of 'descent with modification.'
Definition
The gradualprocess by which something develops or changes into a different, typically more complex form; in biology, the change in heritable characteristics of populations over successive generations.
The Full Story
Latin16th–19th centurywell-attested
The English word 'evolution' derives from Latin 'evolutio' (noun) and 'evolvere' (verb), meaning 'an unrolling, opening out' — specifically the unrolling of a scroll to reveal its contents. 'Evolvere' is composed of the prefix 'ex-' ('out, forth') and 'volvere' ('to roll, turn, revolve'). The Latin 'volvere' descends from the Proto-Indo-European root *wel- ('to turn, roll, wind'), which also yielded Greek 'eilein' ('to roll up, compress'), Lithuanian 'velti' ('to full, mat wool'), and Old English 'wealwian' ('to roll').

Darwin deliberately avoided the word 'evolution' throughout most of On the Origin of Species (1859), preferring 'descent with modification.' He considered 'evolution' too laden with the old embryological idea of preformation — the notion that organisms were pre-packaged in miniature inside the germ. He only used 'evolved' once, as the book's very last word. It was Herbert Spencer, not Darwin, who popularised 'evolution' as a biological term, and Darwin only adopted it in later editions under social pressure.
: 'revolve', 'involve', 'convolve', 'devolve', 'voluble', 'volume' (from the rolled scroll), 'vault', 'waltz', and 'well' (as in a water well, from the turning motion of water). The earliest English use
developmental sense in the 1850s, before Darwin's 'On the Origin of Species' (1859), which paradoxically avoided the word in its first edition. Darwin preferred 'descent with modification'; the Darwinian biological sense became standard by the 1870s, largely through T.H. Huxley and Spencer. Key roots: *wel- (Proto-Indo-European: "to turn, roll, wind"), volvere (Latin: "to roll, revolve, turn around"), ex- (e-) (Latin: "out, forth, outward").
