“There is no agreement on the extent to which metabolism could develop independently of a genetic material. In my opinion, there is no basis in known chemistry for the belief that long sequences of reactions can organize spontaneously -- and every reason to believe that they cannot. The problem of achieving sufficient specificity, whether in aqueous solution or on the surface of a mineral, is so severe that the chance of closing a cycle of reactions as complex as the reverse citric acid cycle, for example, is negligible.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
He argues that metabolism cannot arise spontaneously without genetic templates due to chemical specificity limits.
In simple terms: Metabolism likely needs genetic guidance.
Key Takeaway
Seek evidence before assuming spontaneous complexity.
