There is now even more evidence that life on Earth may have been seeded by material from asteroids or comets.
Prior research has shown how amino acids - the building blocks of life - could form elsewhere in the cosmos.
These molecules can form in two versions, but life on Earth exclusively uses just one of them.
Now an Astrophysical Journal Letters paper shows how conditions around a far-flung star could favour the formation of one type over another.

Interesting, but a long road ahead to prove it.
Kai would probably know more about it, but I'm pretty sure there's biological reasons for why stereo-isomers occur only in one direction. Not why it's either of the two mirror-images, could be either, but if an organism reproduces, the stereo-isomers twist the same way, right? So I guess the other ones died out. Sorry I'm just not buying the panspermia hypothesis (http://en.wikipedia.org/wiki/Panspermia). And besides, it just pushes the origin question farther away, life still had to originate somewhere.
That's the thing that always gets me about exogenesis (that and all the requirements for the basic biochemical reactions necessary for life are available here already). It seems a rather less likely argument that life originated somewhere else in the Universe and then, somehow, found its way to another planet capable of supporting life, than it just originating here in the first place.
I'm open to being proven wrong on that point, but on the balance of existing evidence...
My problem with it is that it simply stretches the argument back further, without answering anything.
A: "Life on this planet came from a meteor."
B: "Ok, so where did that life come from?"
You're not answering the question, you're trying to sweep it under the rug of First Causes.

Also this.
I don't really have anything to add other than echoing Cain's statements. But, i know how y'all love to here my opinions so, I thought I would be kind and share today.
I think that the article is trying to sell the idea of life coming from a meteor, while instead explaining a delivery of organic material that altered the course that life took.
The misleading word is "seeded".
I still say you're all aliens.

I refute and deny being an Alien. Every member of my family, going back for the last 6543 years was from Earth, and none of them ever bred with Aliens. As far as I can tell. But I have been wrong before.

Huh. I wish! Never even
seen any Peyote. And I only have about 500 mushrooms left from last year, and I like to save some for the Summer.
Also, if you are trying to tell me I'm too fucked in the head to realise I actually
am an Alien, then I want a good snootful of whatever drugs are currently eating away at
your brain. (Nanu Nanu . . . . Phox calling Orson) :lulz: ,Are you one of those "The Truth is Out There" numbnuts who sit around Roswell at night, looking up in the sky for the return of your Mother Ship? Because if you are, . . . . . well, if you are, then that sounds like fun. Pretty lulzy, but still fun.

Might be a bit tricky, Geographically, but I live in one of Europes UFO hotspots, so next time the Mothership swings by, I'll get them to drop me at Roswell, and we can take it from there, OK?
