Organic molecules but not amino-acids?
Amino acids
are organic molecules.
No matter what can be done in a lab, it nonetheless requires intelligence and specific conditions and the products have to be kept isolated so that they won't be destroyed.
This isn't so; amino acids have been observed to have formed, and remained formed, in interstellar matter (i.e. comets, interstellar dust, etc.). It isn't the case amino acids only form under lab conditions.
And again what about the left and right handed amino acids that form when conditions are just right?
What about it? Firstly, there's no
a priori reason to believe that just because the majority of amino acids (of those capable of chirality) used in extant life have the same chirality that the very first life also had specified chirality. Secondly, there are a number of means by which amino acids can be preferentially sorted by chirality; noteably simple clay will do it.
I would think that to be more honest we should admit our ignorance rather than continue to give the misleading impression that the Urey Miller experiment shows how life's building blocks could have originated on an early earth leading potentially to organization of early life forms.
Miller & Urey's experiment and subsequent research shows, beyond reasonable doubt, that inorganic processes can and do form organic molecules and together with the best evidence we have of early Earth conditions that there
were organic molecules formed on the early Earth. It does not show that this potentially leads to the organisation of early life forms.
Can you give me a specific example of where such a "misleading impression" has been given? Everytime I've seen the Urey-Miller experiment explained in a textbook it has been clearly described what it does and doesn't show; and that the conditions used in the experiment were different to those now thought likely for the early Earth. It's also been clearly explained that we just don't know how life first formed. Better texts have gone on to discuss some of the more promising ideas on how it did happen.
