John McWhorter, The Story of Human Language [audible.com lecture series]. Awesome lecture series. A more accurate title might be "The Sociology of Language." Discusses the way languages are used and how they evolve in human populations. Also, McWhorter is an excellent lecturer, one of my favorites. His sentences are precise, dense with information, and spiced with a nice, dry wit and colorful turns of phrase. Highly recommended.
His running "Reading Archive" page, where he logs each book, lecture series and podcast he finishes with a short verdict. The page carries no date; the newest entry on it is Timothy Snyder’s On Tyranny (published February 2017), so it was last extended around then.
