You'll need to qualify this statement, thanks!
I would really be interested in how you explain the correlation between species groups and the ratio of isotopes in igneous rocks above and below them. As one example, how do you explain the fact that we can not find any non-avian dinosaurs above igneous rock that dates to 65 million years old by measuring the ratio of isotopes in that rock.
How do you also explain the complete lack of flowering plants, mammals, reptiles, birds, dinosaurs, and vast number of species groups in Carboniferous terrestrial sediments?

Speciation is quantifiable by measuring the divergence between genomes and the rate of gene flow between the populations.
One is scientific, the other is theoretic.
Theories are scientific. The whole point of the scientific method is to construct theories and test them.

When has a fly been anything but?
Just because a fly is Graced by God with the ability to adapt to various situational stressors, does not make it anything but a fly!
This is mutation, not speciation.
I am not, nor ever have been, a FLY!
Where are the test results, and are they quantifiable?
I argue the test results are inherently skewed due to the unquantifiable nature of the test.

If I got this right, you are ignoring my question and proposing your own?I would really be interested in how you explain the correlation between species groups and the ratio of isotopes in igneous rocks above and below them.

If the animals did drown in the flood, we would see them piled on top of each other in the same layer. Diosaurs with Mammals, all maner of creaters bundled together where they would have died. Instead they are spread out in the strata, separated by serveral feet of rock in some cases, never outside the layers of their era.
In short, we would find a bundle of bones in the same layer of rock if the flood was true. This is not what we find.
In fact the early geologists strungled with the flood story and had to abanden it do to the lack of evidence.

It is easy to quantify, simply count the number of times members of the two populations interbreed. There can be a little mixing but not much for them to be counted as separate species.
Not really a big deal.

Actually both are quantifiable. With the Biological Species Concept (which is the currently accepted model for sexually reproducing organisms) the key is reproductive isolation. You have two populations that will not normally interbreed. Sometimes they can't and sometimes they won't for various reasons. When this happens, the populations are reproductively and genetically isolated and usually considered to be separate species.

Simple, if evolution were false, we would find fossils of all previously living things in all layers of strata. In other words, humans, dinosaurs, rabbits, trilobites, andianthasaurus' would be found in all layers of strata. Do you understand now?

Once the piano showed up, you found out how to play it. Where the piano came from is of no consequence.

Yes they sometimes do and that is why, the domestic dog is considered by many to be a subspecies of Canis lupus (the common wolf). The two populations are becoming more reproductively isolated however as the process goes on.
Yes they are considered a subspecies by many but a mutation. Forget about the X-Men, it doesn't work that way.
I am not sure of the point of this but it supports the concept of evolution. These characteristics of a pug are generally heritable therefore are evolution in action. Also, a pug is unlikely to breed with a wolf which pushes many breeds of dog closer to true speciation.
The thing here is that it really helps to know something about a subject before attempting to criticize it. In this context, questions are good.
