Re: The math
1. How many times has it been observed in a science lab that a mutation resulted in an increase of information to a Genome?
A few thousand times, I would bet. I'll start you with just one:
"Conversion of a Peroxiredoxin into a Disulfide Reductase by a Triplet Repeat Expansion," Science 5 October 2001:
Vol. 294. no. 5540, pp. 158 - 160.
Pathways for the reduction of protein disulfide bonds are found in all organisms and are required for the reductive recycling of certain enzymes including the essential protein ribonucleotide reductase. An Escherichia coli strain that lacks both thioredoxin reductase and glutathione reductase grows extremely poorly. Here, we show that a mutation occurring at high frequencies in the gene ahpC, encoding a peroxiredoxin, restores normal growth to this strain. This mutation is the result of a reversible expansion of a triplet nucleotide repeat sequence, leading to the addition of one amino acid that converts the AhpC protein from a peroxidase to a disulfide reductase. The ready mutational interconversion between the two activities could provide an evolutionary advantage to E. coli.
And it's beneficial, besides.

Re: Mutation Rates
You guys got nothing but evobabble to offer and I'm out of here.
That quick, huh? I wanted to talk about human hemoglobin C!

Re: Observed instances of speciation
A dog has been and always will be a dog.
Dogs have no relation at all to coyotes or wolves, huh? They just like to interbreed when they get the chance, but they aren't even cousins? Is that what you're telling us?
