With no intention of being the proverbial wet blanket, I have to point out that the journal in question lacks a rigorous peer review process, and the wide community is, in general, dubious that the conclusion of the existence of extraterrestrial life follows necessarily from the discoveries and work he's done.
Cool, certainly, but I'm keeping my optimism guarded. |

If the conditions are right, life will form. Do I think we'll find extraterrestrial life-forms? We will, of that I'm certain. Do I think they'll be all that different from what we find on Earth? Not really (although Earth is home to some really weird creatures that we consider normal, so take that with a grain of salt).
Do I think we'll find intelligent life? Nope, not without some really powerful help from outside. |

I agree with rae mostly.
I think random chance has a lot to do with evolution, and it's possible that lobstrocities might have beaten out the humonoids on some other planet.

Shame on me for missing that ref.

I disagree with this being a known fact. It's a big unknown just how freakish an occurrence it was to get the ball rolling. Perhaps we are the only world in the galaxy in which life started.
Even if that (life starting) is more common than just once, I think that there are a lot of dead ends that worlds can fall into which prevent higher intelligence. Our own world was trapped in one for a while until a huge meteor wiped out the big lizards. The dinosaurs dominated Earth for a hundred times the length of time humans have.
Even once you reach what we would consider to be higher intelligence, there are societal stagnation traps which could prevent the people from getting to a radio age, which is the first chance we would have to detect them. It took the bubonic plague to break us out of the the feudal system which had completely stagnated society for almost a millennium.
And there are other traps which can destroy a society before it (really) reaches the space age -- I'm not convinced that we can escape those. Nuclear annihilation is never more than a few button presses away, and the environmental annihilation we are perpetrating might already be too far gone to reverse. |

Not disagreeing with your overall point, Zag, but I would like to point out that Europe is not the whole world. The bubonic plague changed Europe significantly, but the rest of the world could have happily gone on regardless and undoubtedly would have made advances despite Europe's non-involvement. (China often seems to hold claim to more firsts than the rest of the world combined)

| Except that China's progress had also stalled for much the same reason. |

I agree. I tried to take a wild stab at the question (in this thread: http://www.greylabyrinth.com/discussion/viewtopic.php?t=13868 ) of whether the probability of life arising given Earth-like conditions (or "conditions suitable for life arising" ... whatever) might be in the range of probabilities that would make it not too unlikely that it would happen once and only once amongst many billions of planets with such conditions. If the range of probabilities in which that would be not too unlikely is very narrow, then, knowing nothing about the actual probability, I might imagine the actual probability is unlikely to fall in that range (sort of a meta-probability problem). |
