This is an educational poster I created to show the evolution of modern Western and Middle Eastern alphabets. It starts with the prehistoric African rock art traditions that would form the foundation of ancient Egyptian hieroglyphs (with perhaps some additional inspiration from Sumerian cuneiform) and then shows derivative forms such as proto-Sinaitic, Phoenician, Greek, Latin, Cyrillic, Hebrew, and Arabic (among others). It's by no means a complete collection of all the scripts that evolved from these foundations, nor does it include alphabets from other literary traditions (e.g. Indian, East Asian, or Mesoamerican ones). Nonetheless, it should go to demonstrate the multicultural, transcontinental heritage of the modern English alphabet we use today.
Cyrillic was created 40 years earlier, but still a minor mistake. You should have included Glagolic, the real "slavic alphabet", that was not inspired by any other alphabet (with some minor exceptions).
Plus cyrillic itself gave birth to other alphabets based on cyrillic, some of them even being a mix of latin and slavic.
Should You ever feel like revise this diagram, I propose that You insert Sabaean (in use between about 600 BC until 200 AD in between Aramaic and Arabic, the Sabaean also begetting the alphabet of Ethiopia, ready formulated about 500 AD I think. Out of the Aramaic, in use as a business language of Achaemenid Persia, Indians learned to write and that was the bridge to alphabets of the East, with one exception, Korea. China and Japan can of course write but their script isn't an alphabet.
