About this episode
The idea that mutations are random is an important concept for evolutionary theory. Yet, multiple areas of research are telling us that mutation placement and type are not at all random. There is also no reason to believe that mutation rates have remained constant over history. Join Dr Rob and he wades into the deep waters of mutation theory.
