How does the discovery of catalytic RNA help to solve the chicken-and egg problem in the origin of life?

Answer 1

If RNA can indeed self-replicate, then the egg could have come first from a single strand of RNA and then produced the chicken

Answer 2

The discovery of catalytic RNA, also known as ribozymes, suggests that RNA molecules could have played a dual role in the early stages of life by both storing genetic information and catalyzing chemical reactions. This finding provides a possible solution to the chicken-and-egg problem because it implies that RNA molecules could have self-replicated and carried out enzymatic functions before the emergence of proteins. This supports the idea of an RNA world preceding the evolution of modern cells with DNA and proteins.
