P.S. two nights ago, I had a dream in which I started giving myself a tonsure with electric clippers, got tired of it partway through and stopped, fluffing the rest of my hair up around it and hoping no one would notice. Thanks, Wordie.
Bears definitely don't have flukes, yarb, plus how would you explain the existence of tappens, given the occasional bear pants issues? Did tappens evolve because of pants issues, or the other way around? Perhaps it was parallel... *cue spooky music*
"To date, no neurological studies of the gray-whale brain have been done. In 2006, however, researchers at Mount Sinai School of Medicine analyzed the brains of two other baleen species — humpback and finback whales — as well as those of a number of toothed whales like dolphins and killer and sperm whales. The study revealed brain structures surprisingly similar to our own. Some, in fact, contained large concentrations of spindle cells — often referred to as the cells that make us human because of their link to higher cognitive functions like self-awareness, a sense of compassion and linguistic expression — with the added kick that whales evolved these same highly specialized neurons as many as 15 million years before we humans did, a stunning instance of a phenomenon biologists refer to as parallel evolution."
