Seven pairs of clean animals.
Also, a favorable mutation is not necessarily a one of event.
Oh, so the duck-billed platypus arose in different locales independent of other populations of duck-billed platypus?
When examined, none of the worldwide flood propositions hold up.
On the contrary, over the course of my less-than-five-decades on this planet, geology has moved from near lock-step uniformitarian to increasingly catastrophic. There are evidences of massive flooding worldwide. There are legends among every people on earth of a massive flood. That is no accident.
The proof of just what happened is literally in the ground you walk on.
What happened? You say you have proof in the ground we walk on. Lay it out for me.
Clean animals?
Of course the mutation my only occur within the species but it may be a common mutation which becomes favorable as climate changes.
Plate tectonics and specifically structural geology explain much of what we see in faults, folds, earthquakes, volcanos, etc. More is discovered, proven, disproven and observed as time goes by as is the case with science. In the presentations of flood geology, much is made of the discovery of fossil bearing sedimentary rock at the top of the Himalayan Mountains. Geology and plate collisions between the Eurasian and Indian plates will lead one to the conclusion that it would be surprising is there were not such sedimentary rocks on the peaks.
I’ve taken the time and watched some videos on flood geology. You should look at something on current geological thought. The flood geology videos encourage believers to confront and ridicule contemporary scientific theories. At least you should understand in some detail what you reject.
Also, flood geology is full of straw men and other logical fallacies. The definitions and premises that flood geologists attribute to contemporary geology and evolutionary biology often are total misrepresentation.
