Primordial Soup Cannot Tolerate Salt

They effectively dismember membranes and stop RNA units from forming anything longer than dimers. With mechanisms proposed to concentrate these for abiogenesis, it also appears that these mechanisms would also concentrate salt.

Not all bodies of water would contain all that much salt, or life just gradually adapted as salt content increased, just like when the atmosThe requested document is freely available only to registered users with an online subscription to AstrobiologyYou can purchase this article belowClick here for the publisher's subscription informationCatchWord has not recognised you as a registered user.If you have registered to access a personal subscription to this title please enter your username and password[/i][This message has been edited by nos482, 09-23-2002]

The point is is that the "primordial soup" theory relies on a mechanism to concentrate amino acids and other organic molecules. This would also concentrate salt, which would stop macromolecules forming.

How does life exist in the oceans of today if it is so toxic to it?Also, it has been shown that life may have had to "start over" several times in the past as well because of early mass extinctions.[This message has been edited by nos482, 09-23-2002]

And they got that way from trail and error and a lucky mutation or two.

There are many theories on abiogenesis as well where some could have occured along side each other instead of just one. In other words life could have started on this planet through several different methods until one, or more, "caught on". How life started is still mostly an unknown, though.[This message has been edited by nos482, 09-23-2002]

I have no real opinion on abiogenesis to begin with since it is currently unknowable how life actually got started on Earth. It could be god, or it could have been the Big Blue Banana for all we know. At least the scientists are looking for a rational explaination instead of "Puff, GOD DID IT!".

I know there are other theories out there... however, the primordial soup theory is the main evolutionist model right now and taught in almost every school. Now, you are talking about numerous problems with my idea. What idea are you talking about? What I posted was just about how organic molecules cannot survive in salty water. Experimentally provable. So this is just further evidence that the primordial soup theory is wrong.

Evolution has nothing to do with how life got started.

Didn't I say that before?

Then why bring this up?"the primordial soup theory is the main 'evolutionist' model right now and taught in almost every school."[This message has been edited by nos482, 09-25-2002]
