Brit.

/mjuːˈteɪʃn̩ɪz(ə)m/,

/mjuːˈteɪʃənɪz(ə)m/, U.S.

/mjuˈteɪʃəˌnɪz(ə)m/

Origin: Formed within English, by derivation; modelled on a French lexical item. Etymons: mutation n., -ism suffix.

Etymology: < mutation n. + -ism suffix, after French mutationnisme (H. Colin Revue de philosophie (1910) 17 336). Compare earlier mutationist n., mutation theory n.

Biology. Now historical.

The view that mutation, rather than natural selection, is the main driving force in evolution; esp. = mutation theory n.
