...producing a chirally pure polypetide length of significance is another.
Since the link provided only gets me to the login page of the magazine, I do not know what it said. Could you either copy a short summery from the article or summerize it yourself?
Some thoughts before even finding out what the article said:
Chirality is still, to my knowledge, a BIG problem for abiogenesis as all modern living cells use exclusively L-form amino acids. Since one of the shortest protein chains known, insulin, is about 150 peptides in length, it would seem reasonable to look for a naturalistic process that can produce polypeptide chains of at least 150 all L-form amino acids... I don't think they have found it yet but there isn't much sense in discusssing the next level of problems unless a significant answer for naturally producing pure chirality is found first.
Does this article address this problem?
Is the faith of naturalists any better than the faith of creationists?
