Life? If so, abiogensis or panspermia?
If life actually inhabits this newly discovered planet, and if it is the same kind of life as we have here on Earth”the only kind of life we know about”then we have two alternatives for explaining our spatially separated co-existence: either abiogenesis occurs multi-regionally or panspermia really works.
IMO, this new discovery makes robotic space exploration even more urgent. I would prefer to forget about those romantic notions of torporized humans in pods going to these places to gather information. Waste of NASA's money, anyway. Maybe Simonyi would care to pay for it.

um, hoot, you do realize that panspermia requires abiogenesis, right? It might explain how life got to a planet, but not how life got started. i mean jeez, you have a whole thread (at 305 posts) to figure that out. you still haven't apparently.
Now, really! Take a closer look at my two alternatives:

Either abiogernesis is multi-regional or it isn't. If it is then it could have happened on both planets. If it isn't, then the Johnny Appleseed of panspermia had to carry those precious spores from the planet that hosted abiogenesis to the one that didn't. No?

Re: Life? If so, abiogensis or panspermia?
It implies either abiogenesis or panspermia. It does not imply that panspermia requires abiogenesis.
NO! It implies EITHER multi-regional abiogenesis OR single-origin abiogenesis, which would require panspermia to account for life on both planets. What's so difficult about that?

Re: Life? If so, abiogensis or panspermia?
AZPaul3 asks:
And if such life is found on this planet and it turns out to be of a unique chemistry with a unique code in a unique format then what would this say?
In my opinion, it would say to Earthly life that we could have been the winners of the Life-on-Earth contest, while our vanquished competitor could have turned the tides on this Earth-like planet X and vanquished our kind. (Does this new planet have a name yet?). I have two guesses on this ubiquitous-life theory: 1) Life on Planet X will be the same as life on Earth, nothing strage about it; or 2) Life on Planet X will be different from life on Earth, but neither planet supports both kinds of life simultaneously. The third option I would reject: 3) Both kinds of life occupy Planet X.

Re: Life? If so, abiogensis or panspermia?
jar's admonition:
Either way, Abiogenesis happened.
It happened once, or more than once, by one method or multiple methods, but Abiogenesis happened.
The job now is to continue searching for possible Theories of Abiogenesis.
Well, of course. Who would disagree with that? The same could be said about the big bang and consciousness. Keep searching.
