Our findings demonstrate, for the first time with a homogeneously selected sample, that a relationship exists for typical star-forming galaxies at z = 1 - 1.5 and that it is surprisingly similar to that seen locally. Therefore, star-forming galaxies at z = 1 - 1.5 are no less metal abundant than gala","authors_text":"David Sobral (Leiden), Ian Smail (Durham), James E. Geach (Herts), John P.
