Scientists have found, in the Arctic, the 375-million-year-old fossil of the missing link between ocean-dwelling fishes and terrestrial creatures. The creature, Tiktaalik, has a specialized bone configuration in its front fins that signals the development of a wrist joint. Mostly, scientists are happy because the existence of this animal had been predicted, and they had been searching for it in specific regions known to have fossils from the correct time period. Also conforming to prediction: a cottage industry of freaky Tiktaalik-inspired art. Seems every time there’s a noteworthy scientific discovery, someone makes a t-shirt (Remember “Ask me about the avian flu?”) or paints a weird picture, or writes a song. Kinda sweet to see so much creativity out there, but I’m not about to start singing the “Devonian Blues.” —Martha Harbison
