By Stephen Spector on Literary Hub site:
Let’s face it: writing isn’t a natural act. Our ancestors may have started speaking between 50,000 and 2 million years ago, but it was only 5,000 years ago that people started to write.
Three thousand more years passed before they began to use a system of little points that eventually evolved into our modern punctuation.
Then it took centuries for those punctuation practices to develop.
To put that in perspective, let’s say that humanity has existed for 24 hours.
By traditional estimates, more than 23 of those hours passed before people invented writing. And punctuation didn’t come along until closer to midnight.
