ASU researcher may have discovered key to life before its origin on Earth

But they don't know what causes this bias. I wonder what it could be...
Two theories I have heard; Polarisation of light in interstellar space or elsewhere causes certain molecules to be favoured in certain regions; perhaps if the universe as a whole were considered the bias would even itself out. Or A bias in the very make up of our universe- in particular the parity violation in certain interactions http://en.wikipedia.org/wiki/Parity_...rity_violation Somehow, but I don't know if anyone knows quite how, this might bias the handedness of biological molecules all over the universe. |

Pristine? Some of those meteorites landed in manure. Claims were made in 2000 that extraterrestrial life had been found in them. Strangely enough exactly the sort of life you find on a rock if you throw in the middle of a farmyard.

Excellent.
"In other words, a molecular trait that defines life seems to have broader distribution as well as a long cosmic lineage." Might as well have said "cosmic ancestry," but could this be considered supportive of panspermia?

so the CA was a cacky-hander (sorry to all other LHers for the crude reference). Anyway, a bias in the orientation of precursor organic molecules, hardly constitues the transmission of biological information of such complexity that it supplants evolution as CA claims, now does it, or is this what you have been reduced to claiming, since all else has been debunked. A hydrogen atom can have a long 'cosmic lineage' omg..ca!

I've not made any claims nor am I aware "all else has been debunked" which regards strong panspermia, or as you say, the cacky-hander CA.
Whatever the case, this simply appears to reinforce the notion that physics and chemistry are everywhere the same, which, IMO, supports panspermia.

No, just a confirmation that the materials of life are common. We already knew that the molecular precursors of life were common, this is just another refinement of that. Still just raw materials, nothing about panspermia, or actual extraterrestrial life.

I don't know you well enough to assess possible sarcasm. The possible life detected in the Martian meteorite was not anything like what you would find if you flung it in a barnyard. In fact it was like nothing on earth at all. It was uniquely small, which is in fact one of the things that led to the current understanding that it was not life. However, I would say the case is not closed; like many things in science, the investigation goes on. |

If the ingredients for Life are more abundant off planet than on, chemistry and physics are everywhere the same, and hallmarks of Life like this excess handedness in amino acids are found in meteorites free of earthly contaminates, why not suggest possible et life or panspermia?

Right, he was referring to the Murchison meteorite which was strewn across pastures. Even still, this finding seems to reinforce what they found 10yrs ago, an excess left handedness in amino acids.

All we've proved is that we're made of common materials. Again.
