For several years many scientists have supported the idea that life got its start on our planet due to a series of events that led to the creation of RNA molecules—it seems like a strong candidate because it is able to both store information and act as a catalyst. A team of chemists at Ludwig Maximilian University of Munich has shown how the purines adenine and guanine can be synthesized easily and in reasonable yields, offering more evidence that RNA could have served as the origin of life on Earth. In their paper published in the journal Science, the team describes the process they took in looking for evidence that RNA could have been the first self-replicating molecule that eventually led to all life on our planet and what they found. http://phys.org/news/2016-05-chemists-evidence-rna-life.html http://www.sciencemag.org/news/2016/05/rna-world-inches-closer-explaining-origins-life Paper: http://science.sciencemag.org/content/352/6287/833
