By trying to speed up, molecular processes can become more reliable – a phenomenon that may have helped life evolve from relatively simple chemicals. Understanding how speed plays a role in cellular replication could add a crucial variable to Charles Darwin’s theory of evolution, in which natural selection drives reproductive success.

The finding comes from Kabir Husain at University College London, Riccardo Ravasio at the University of Chicago and their colleagues, who were frustrated by an experiment…
