Bet you didn't know : That Neanderthals already knew how clocks functioned and that they had even fabricated some very sophisticated ones. The only problem was that they operated on batteries and as everyone knows, batteries were invented much later....so sad!
Undeterred, our prehistoric ancestors made their clocks decorative objects on which they painted their pets and proudly hung on the wals of their caves (just above their TVs).
Here is a faithful reproduction of one of primitive art's masterpieces.
