Thank you, this is fascinating! Do you have any recommended reading?
But I do recall enjoying diagrams such as this illustrating how different modern alphabets are related via historical counterparts (there are similar diagrams showing how Hebrew and Arabic emerges from Phoenician, as well as comparisons to runes): https://en.m.wikipedia.org/wiki/Brahmi_script#/media/File%3A...
I also rather enjoyed reading about the history from Hieroglyphs, to Hieratic, to Phoenician (as well as Phoenician history in general). But unfortunately, don’t recall where. Start with Wikipedia :)
