" Spread your arms out to your sides, like a plane. Your wingspan is a timeline. Your left fingertip represents the time of the first single-celled life on earth. And your right fingertip is right this minute. Between the two is 3.7 billion years of time, the history of life on earth.

From your left fingertip, all the way up your arm, past your left shoulder, across your chest, and past your right shoulder, life on earth is nothing but bacteria. By the time you reach your right wrist, the most impressive form of life on earth, the king of beasts, is the worm. In the middle of your right palm you finally get your dinosaurs, and they're extinct by your last finger joint.

Run your eyes along that history again so far. All that history, all that life, and still no appearance by the Main Attraction, the species for whom everything is supposedly made - humankind.

So when do humans finally show up at the party? Well it's more than fashionably late. Homo sapiens fits in one fingernail clipping. "
