Исторически так сложилось. Долгое время натуральные лады тоже не имели названия, пока в XIX веке (если не ошибаюсь) им дали названия, которые потом вошли в употребление.

The term Aeolian mode fell into disuse in medieval Europe, as church music based itself around eight musical modes: the relative natural scales in D, E, F and G, each with their authentic and plagal counterparts.

The Dorian mode is named after the Dorian Greeks. In Greek music theory it was based on the Dorian tetrachord: descending, a series of falling intervals of two whole tones followed by a semitone. Applied to a whole octave, the Dorian mode was built upon two Dorian tetrachords separated by a whole tone. This is the same as playing all the white notes of a piano (ascending, as in the modern reckoning) from E to E: E F G A | B C D E.

he early Christian church developed a system of eight musical modes (the octoechos), which mediaeval music scholars related to the ancient Greek modes. Misinterpreting the Latin texts of Boethius, medieval modes were given the wrong Greek names. Thus, in medieval and modern music, the Dorian mode is a diatonic scale or musical mode which corresponds to the white keys of the piano from "D" to "D".
