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
Information is one of the first words that comes up whenever people try to define life. Any living system must be able to store information and pass them on to the next generation. The stored information are instructions used to build the structures and functions necessary for cellular life to operate such as metabolism, membranes, … Continue reading Origin of protein translation: a factory that built itself
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
