So the magic evolutionary wand is waved three independent times and three times coronary vessels appear. No one has ever observed anything like this occurring, it only occurs in the minds of evolutionists, not in the real world.
If we look at the distribution of coronary vessels in vertebrates, we can see that it is a disjunct one. They are present in birds, crocodiles (including alligators), mammals, some (but not all) teleost fish...<snip>
You have failed to make the slightest attempt to explain how coronary blood vessels supposedly evolved. You mention ‘distribution’, but you fail to explain how coronary blood vessels originated. Your arguments are nothing more than a futile attempt to hide the fact that you simply have no evolutionary explanations. As always, you completely fail to take into account the overall complexity of the CV system and you seem completely oblivious to the adverse effects (pathophysiology) of structural and functional changes to the CV system.

You have committed yet another logical fallacy. This time it is the either-or fallacy. Your problem is that attempting to discredit A does not prove B. The really pitiful thing about your argument is that, as I have been saying all along, a non functioning CV system will result in death and extinction, not evolution. Your argument here is powerful evidence against evolution because coronary blood vessels that cannot meet the metabolic needs of the myocardium will result in heart failure.

Your one word evolutionary explanation for the origin of coronary blood vessels (‘added’) is completely devoid of any scientific or any intellectual content. To say that coronary vessels were merely ‘added’ is about as scientific as saying a frog transformed itself into a prince.
