My great grand daddy was a dinosaur My brother was a monkey. I came from what had come before. I think one was a donkey. A relative of long ago I'm sure once was a frog. With certainty my fam'ly tree Had a fuzzy wuzzy dog. For we are life and lively be And won't accept we're done For we're constructed of The stuff of stars And we're still having fun. My babies will be molecules That leap empty space. They may be cockeyed cyborgs Or perhaps the human race, But crazy be or lazy be Matters not a bit For the universe Would be much worse If we'd ever quit. Three cheers for evolution And life that jumps to Mars, Whether it be rabbits Or living autocars. We'll last as long as we can change And dance and sing our songs. We'll leap across the galaxy And bang the stars like gongs.
