Acquiring somatic mutations is not "rewriting its own DNA", it's just acquiring mutations. You can't replicate a piece of DNA without the chance of a mutation happening. The error rate in humans is about 1e-9 mutations/base, so by the time you've grown a brain you're likely to have a whole bunch of somatic mutations just by chance.
