"Many mutations are not caused by anything mutagenic - it is the replication system itself that allows for "errors" to creep in, as a major source of normal variation. ... If DNA replication were normally "error"-free we likely wouldn't have enough variation to speciate at all."

Wonderful statement of 'faith' - you have supporting peer reviewed research documentation?

Without reading this idiot thread closely (I'm going to die within the next 30 years) have you (Foule) never heard of the "genetic clock" so well documented that it's utterly uncontroversial, except about it's rate (i.e. did chimps and humans separate 3.5 million years ago, or 3.25, or 3.75?)

I'll spell it out clearer... you have PROOF that it is the replication system itself that allows for "errors" to creep in with no external mutagenic factors?

Hint: It's tricky to prove a total negative .... :-)
