>Stuart, you hit the nail on the head! Yes, evolution is inextricably tied to error rate, and DNA transcription enzymes allowing a particular error rate (which varies from organism to organism) IS indeed a feature not a bug! Many have written on this, Manfred Eigen derived specific error rates that led to the so-called "error catastrophe".

Yup not only do different organisms have different mutation rates but mutation rates can change fro gene to gene in a single organism. For example, the genes expressed in the human brain are mutating faster than most other human genes. And our lymphocytes have the ability to deliberately mutate their antigen receptor genes, such as antibodies, within the lifetime of single cell, in order to keep up with mutating bacteria and viruses and protect us from infections.
