Brain's gone soft? Maybe not in dogs though - new research shows their brains might actually shrink as they evolve into weirdly shaped pups we call "breeds". This thing got me thinking: do humans get smarter or dumber too if that happened to us over time. Can't ask the pugs, all brain capacity wasted on sniffing treats and snuggling strangers probably. What's happening in those canine noggins anyway? Maybe they're losing some higher-level thought functions - I mean who needs complex problem-solving when you have slobbery kisses as a currency? Our furry pals got more going for them than we give 'em credit, right.
