Because this is essentially the same theory for creationists and non-creationists there is no testable differentiation between the two models for the period of time where they overlap. To find a testable differentiation we need to look back into the past, to the point where the two models diverge.

From Two of Every Kind (see box at bottom):



So we should see the effect of the orchard vs tree arrangement in the fossil and genetic record. If creationism were true we should see the orchard, and further, it should be repeated after the flood event, which should also show up as an extinction event that winnows species down to the original kinds again, with the same kinds before and after the flood:

[color:"red"]Theory #1b (a corollary of theory #1 if creationism is true):
That as we go back in time from generation to generation, the species will converge on their parent "original kinds" at the same time and in one general location ... once for the hypothetical flood event and once again for creation.[/color]

ie - there should be a clear delineation in the fossil and geological record, at two different times and places, and we should not find any evidence that continues at all below the second delineation, to say nothing of evidence that forms a tree of relationships:

However if evolution\geology were true then there should be no repeated period of species before and after an extinction event and the record should continue as far as there is evidence.

[color:"blue"]Theory #1c (a corollary of theory #1 if evolution\geology is true):
That as we go back in time from generation to generation, the species will converge on their individual parent species at different times and different places ... in a fairly continuous process that forms a tree-like pattern of relationships.[/color]

And then, if all life is related to some original population of life, we should find evidence that forms a tree (if not a bush) showing the relationships:

If we can agree on this and the tests for the different corollaries then we can move on to the evidence for descent from parent species or kinds and see if

(1) the theory #1 can, or cannot, explain the evidence,
(2) the theory #1b can, or cannot, explain the evidence,
(3) the theory #1c can, or cannot, explain the evidence.

Enjoy.
