Not necessarily. Why isn't it possible that other things evolved later, but we had clotting from the beginning? I am not an evolutionist, but that is something that could be a logical explanation from their side.

Saying that we had clotting blood from the beginning, that it did not evolve is NOT an argument for evolution.

True. They could exlain it away as not necessarily being an argument against it though; it could be neutral if their explanation is correct.

What I am more interested in knowing due to their explanation is how blood started (since in the earliest creatures according to evolutionists did not have blood). How the heck could it just "show up" with all the necessary parts coming together at ONCE? How on Earth could the different blood types just come together for different species?
