Origins Of Life: Chemistry And Evolution - Astrobiology

Direct chemical synthesis and chemical evolution are conceptually different models for the prebiotic origin of RNA and other biopolymers. These models generate distinct predictions and motivate different experimental approaches. Here, we compare these two models. In the direct chemical synthesis model, the inherent chemical reactivities of prebiotic compounds on the ancient Earth led to RNA, […] The post Origins Of Life: Chemistry And Evolution …
