Parrot sings Mozart. If this parrot singing the Queen of the Night's great aria from The Magic Flute does not blow your mind, your mind is unblowable. (Thanks to Celinafink who uploaded this video to YouTube.)
Although our closest genetic kin in the animal kingdom are the apes, our closest functional relatives are birds. We've been seeing individual details supporting this conclusion for some time on Babel's Dawn, and now a paper has appeared in Nature Reviews|Neuroscience that pulls together the "astonishing cognitive, neural and molecular parallels" [p.747] matching humans with birds. For the past six million years our lineage has been moving steadily away from the other apes and following a convergent path that birds took much earlier. Then we began to build something on the bird foundation that birds never managed… unless some of them did.
