In fact there are too many to list, so you better rethink your assertion that "mutation doesn't cause extinction".
There is more than ample proof to the contrary.
DDT doesn't cause a MUTATION (temporary or otherwise)that interferes with egg shell formation, it interferes with the chemical process. Moreover Bald Eagles have not gone extinct.
Prion disease is also not a mutation, nor causes or is caused by a mutation, neither has it caused elk or any other species to go extinct.
You have yet to provide even a SINGLE example of an extinction event that was caused by mutation.
Neither have you put forth a “scientific” theory of creationism, and the idiotic source you cited DID talk about Noah's Ark on the very first figure, titled FIGURE ONE.
And once again, evidence in science is not “proof”, ample or otherwise. Moreover there is not a shred of evidence in anything you provided that either...
a) in the past a species has gone extinct due to mutation
or...
b) we are threatened with extinction at some point in the future due to mutation.
