Why evolution needs noise: in the light of QT45 ribozyme

~ Fadel Fakih ~ Leave a comment

A violet amethyst crystal, while beautiful on the outside, is a highly ordered structure at the microscopic level, and therefore cannot evolve. In contrast, a gas is highly random and cannot store any form of structure or information. Life sits right there in the middle, a highly structured and complex system with a tolerated degree … Continue reading Why evolution needs noise: in the light of QT45 ribozyme

DNA Replication and Convergent Evolution: How Life Reinvented a Core Process

~ Fadel Fakih ~ Leave a comment

Since the very beginning of life, organisms have needed a way to store and pass on information. Current knowledge suggests that the first form of genetic information was stored in ribonucleic acid (RNA). Over time, life invented DNA, a chemically more stable molecule, for long-term information storage and faithful inheritance across generations. This genetic information … Continue reading DNA Replication and Convergent Evolution: How Life Reinvented a Core Process
