Nearly all mutations are harmful or neutral at best.
This is a patently false premise propounded by creationists over and over:

This though, LOL:
This is blatantly false. On the contrary, the creation axiom has been overwhelmingly supported by ALL of these fields, particularly genetics, archeology, geology and physics. 700,000 layers don't correspond to years but to snowfalls. How else can you account for the fact that an abandoned plane left there just a few years earlier was found miles under the ice?
I'm not sure what science journals you read but they aren't the ones actual scientists are publishing in. To date there has been not one single iota of scientific evidence supporting the "creationist axiom". Your third sentence displays a complete lack of understanding of ice core dating and the general climate of Antarctica, the DRIEST continent on the planet. So please cite some sources for a plane found under miles of ice. Aside from that check out a few laymen’s sites on how ice cores are dated:

TYPO3 ExceptionThis doesn't pertain to finches so further discussion should be continued in a new post (after you've read the ascribed above).
So far, finches or no, your science is bad.
PS, the "evolutionary axiom" postulates nothing about abiogenisis. That too is a creationist attempt to make the argument philosophical rather than evidential.
Back to finches somebody.
