“ Holliger’s team looked for catalytic activity in small RNAs (between 20 and 40 nucleotides in length), allowing for small changes in length in each cycle of mutation. They found a 45-nucleotide molecule that they christened QT45 (“quite tiny”) that could seize another RNA strand and copy it. “In principle it can copy any sequence,” Holliger said.”
replyYou need evolution to have life. Why is mutation a deal-breaker?
reply> You need evolution to have life.
replyI don't think you can say this with certainty. It is assumed that life and evolution go hand-in-hand from the beginning but it is not proven to be the case.
How exactly can it be proven? Even if we create life from scratch and see it evolve, it won't be a definitive proof
replyIt could be proven if there was a record found of something that predated the currently known fossilized bits from really long ago that would give a hint about how life at that stage was put together. This is highly unlikely to happen.
