29 Generations Ago (from 2020 CE)
Spaces between words started circa 800 CE. Over the next few centuries, writing evolved. By the invention of the printing press in 1440, we had punctuation pretty similar to today’s standard. About halfway, at the time of the Magna Carta in 1215, we still had mostly uppercase with spaces between words and an occasional period. Punctuation and spelling mostly standardized starting in the 1300s for the next century, just in time for the printing press.
