Over 32,000 years, the letter 'A' evolved from early cave drawings of oxen by ancient ancestors through various cultures, each modifying the symbol slightly, including the Egyptians drawing an ox hieroglyph, Phoenicians taking the ox head as a symbol that became the letter "Aleph", Greeks borrowing and rotating it to "Alpha", and eventually becoming our simplified lowercase letter "A". While technology has advanced communication greatly, some of the visual meaning was lost as symbols became abstract letters.
