I know you were joking here, but evolution only seems random from the outside looking in. In any given environment, life will evolve to take advantage of the available natural resources in the most efficient manner possible. Granted, the environment differs greatly from planet to planet, but I think we can agree that any planet hosting life as we know it will have some remarkable similarities to earth. Life will evolve in the best way to take advantage of that environment- two eyes to see in 3D, bipedal for mobility, upper limbs to manipulate things physically, brains to control it all, a mouth at the top and an ass at the bottom because gravity only knows down, some sense of smell to detect fuel(food), ears (or something similar) to detect predators, and some form of genitalia to reproduce.
I often wonder if we are Earth's end-of-the-line inhabitant. Animals evolve to adapt to their environments. Us humans adapt the environment to suit us. Have we stopped evolving? It's a dangerous situation if we have, because then we become a non-changing environment for all the creepy-crawlies we are host to. Bacteria will rule the world in 100 million years! /rant
