The original wild tomatoes come from South America, and can still be
found in Peru, Bolivia, Ecuador, Chile and Colombia. Rather oddly there is
no word for the plant in early South American Indian languages, and
certainly no record of its cultivation, so it seems unlikely that any of the
early local inhabitants found a use for it. Of the thirteen wild species
considered as ‘tomatoes’, no single one of these is recognized as being the
direct ancestor of the modern cultivated tomato, though genetically the
closest relative is the tiny fruited Lycopersicon pimpinellifolium, or
redcurrant tomato.
