If I had to place bets, it would be that life on other planets, would be dangerously similar to ours. As for 're-rolling the dice' on earth, every species of birds, reptiles, primates, etc, would evolve differently, however, they would still, end up, very similar to what we have now. They would all end up with 2 eyes, one mouth, one nose, because it works best.

Consider this, all, alien, automobiles, would also go through a similar evolution as ours have. There is no way around it. All cars need 4 wheels, a body, steering wheel, etc. The first ' steering wheel' was a stick. then a round wheel. The first materials, out of necessity would be metal, wood, leather, etc. This would make the first cars on other planets, almost identical to the model A, on earth. . How could an automobile, built be aliens, on another planet, evolve any differently, than ours have, on earth?? The same is probably true with life's chemical process's. We could probably interbreed with aliens also.

Interesting paper on a thermodynamic origin of life. Aliens could even have RNA and DNA.
