So no examples of a species going extinct due to high mutation rates, and yet you somehow seem sure that it will happen despite the COMPLETE AND TOTAL ABSENCE OF EVIDENCE.

Error prone DNA polymerase introduces changes randomly over the entire genome that is being copied. It is not like the immune system where specific elements are shuffled randomly in a directed manner. It is the introduction of a error prone copy mechanism over the ENTIRE bacterial genome, not “hot spots”.

So why would bacteria even HAVE a gene for an error prone DNA polymerase? Of course they NEED their regular DNA polymerase, but why do they carry around a copy of an error prone one? Moreover, why do they express this error prone DNA polymerase in response to stress?

What might happen to a bacteria undergoing stress that is using an error prone DNA polymerase that is less likely to happen to a bacteria undergoing stress that is using a high fidelity DNA polymerase?

I asked you, do you have PROOF that mutations did NOT cause extinctions of species?

\ Please answer the question.

[Nathan Zachary]

how about Spontaneous deleterious mutation in Arabidopsis thaliana?

[Nathan Zachary]

Gee, even EVO's admit mutation causes extiction.
