Original sentence: Biologists propose that natural selection of self replicating RNA molecules is possible and this has been confirmed  invitro.It is evident that AiG are aware of the concept of natural selection about which they have written (at least one) article.This brings into question whether life should be arbitrarily defined as post-first-cell or post-first-replicating-molecule.This criticisms is also at odds with how mainstream science understands the process.Yet such arguments conflict with current ideas with respect to the RNA world hypothesis
Edited sentence: Biologists propose that natural selection of self replicating RNA molecules is possible, e.However, this is template-directed replication rather than self-replication, and one of the co-authors, Gerald Joyce, wrote:.It is evident that AiG are aware of the concept of natural selection about which they have written a number of articles.The most reasonable assumption is that life did not start with RNA ….The transition to an RNA world, like the origins of life in general, is fraught with uncertainty and is plagued by a lack of experimental data.Yet such arguments conflict with current ideas with respect to the RNA world hypothesis, although this is still a hypothesis, hence its name, and has a number of difficulties.[RNA evolution and the origins of life, Nature 338:217–224, 1989]
