Within a few months, the Goddard scientists found glycine embedded in aluminum foil of the collecting apparatus. They had spent the time since then confirming that the glycine indeed came from the comet and not from contamination.

“It’s not necessarily particularly surprising,” Dr. Elsila said of her extraterrestrial glycine in a phone conversation Tuesday. “I would have been surprised if it wasn’t there.”

Dr. Elsila and her colleagues were able to show that the glycine from the comet had heavier quantities of the isotope carbon 13 than what occurs on Earth. They also detected a second amino acid, beta-alanine, but the quantities were too minuscule to confirm.

The findings were presented Sunday at a Washington meeting of the American Chemical Society and will be published in the journal Meteoritics & Planetary Science.

Interesting, but it still doesn't say anything about the process by which pseudo-life becomes actual life. That essential block of information has been missing from the Abiogenesis Theory for a long time.

Please, if someone has evidence to the contrary; that there is a confirmed process by which pseudo-life becomes actual life, let me know. I really want to know.

Since defining life itself it's hard (once you get to the molecular level) this is an important clue to fill in the gap.

Life does have a definition that we can use. I forget all of the elements of it currently, but using that definition, it's been determined that microbes such as bacteria, molds, fungi, etc. meet those qualifications, but nucleotide constructs like viruses are not actual life (they fail at least one of the qualifications to be defined as life)

I'll check out that videowhen I get a chance, though, Jimbo. Thanks for the heads up
