The evolution of the Latin alphabet. Larger. (Originally from here.)
You can see how the letter G was created from the C (in order to distinguish the voiceless /k/-sound from the voiced /g/). The Z was lost and reintroduced; the Y evolved into the V, and then the original letterform was later reintroduced. The earliest roots of the modern Latin alphabet can possibly be traced through Phoenician to the Proto-Sinaitic glyphs found in Sinai and Egypt, dating all the way back to 1900 BC.
