ThereIsNoDog Posted August 18, 2009 Share Posted August 18, 2009 some serious implications here Or it could mean that the building blocks of life are "universal" under the conditions needed to form them, and that they formed elsewhere, as well as on earth.

ThereIsNoDog Posted August 18, 2009 Share Posted August 18, 2009 parallel evolution rarely occurs on Earth. That doesn't mean that amino acid formation isn't an inevitable occurrence when the "perfect storm" of conditions exists. Merely finding glycine on a comet doesn't prove that life existed/exists elsewhere. Or that life only started because asteroids seeded the earth with biological material. I mean, how many asteroids would have needed to hit the earth's oceans, and in close proximity, to form the first organism? And how did those compounds form, wherever they came from, if they came from a life-producing planet? Furthermore, many biological compounds need to be synthesized; they don't just appear out of thin air. Link to comment Share on other sites More sharing options...
