From grunts to grammar. The Irish 'after doing.' The winning NGD poem!

972. How did humans evolve from grunting ancestors to masters of language and poetry? This week, we explore fascinating theories on the origins of human language, including the laugh-inducing Bow-Wow and Pooh-Pooh theories. We also delve into Irish-English calques for St. Patrick's Day (and in response to a question from a Grammarpaloozian) and celebrate Leslie F. Miller's winning limerick from the National Grammar Day contest.
