What a long word salad to try and hand wave the fact that there's no definition of "kind" away. The following sentence shows that the term "kind", along with all other sciency-sounding terms used in the pseudoscience of creationism is always pseudoscience.

The empirical evidence indicate the opposite.
We've got empirical evidence that the first cellular life forms (as we know it) were prokaryotic cells. We've got them in the form of fossils in the lowest and oldest rocks containing cellular fossils, indicating that the most complex form of life existed as prokaryotic unicellular organisms at that stage. No evidence of more complex life then.
What empirical evidence do you have that "biological diversity had a more complex starting point"? Just a whole variety of holy books and wishful thinking?
