"If our cells couldn't mutate, we could never get cancer, but we also couldn't evolve. We would be fixed forever. What this means in practice is that although evolution is sometimes tough on the individual, it's beneficial for the species." - Olaf Heidenreich (The Body, by Bill Bryson) And that's why you're reading this on a digital platform today, and not picking gnats off your mate as you two sit on a tree branch somewhere. Again, you should really read this book.
