Linear A
Arthur Evans considered the Cypro-Minoan syllabary to be a result of uninterrupted evolution of the Minoan Linear A script. He believed that the script was brought to Cyprus by Minoan colonizers or migrants. Evans' theory was uncritically supported until recently, when it was shown that the earliest Cypro-Minoan inscriptions were separated from the earliest texts in Linear A by less than a century, yet the Cypro-Minoan script at its earliest stage was substantially different from Linear A: it contained only syllabic signs while Linear A and its descendant Linear B both contained multiple ideograms, and its form was adapted to writing on clay while Linear A was better suited to writing with ink. The Linear B script that emerged a century later still retained many more features from, and most of the signary of, Linear A. All this evidence indicates a one-time introduction rather than long-time development.
