[Derrald]

Actually, eurythrocytes, leukocytes, thrombocytes, all are produced from one type of master blood stem cell, so it is conceivable that a being entirely lacking of thrombocytes could easily receive them, as the master blood cell holds the key to all types of blood cell. So, in the model of evolution, blood did not occur first, and then things bled to death. Rather, when blood came about, the entire package came with it. In short, blood never did exist without the clotting mechanism and the entire assumption that we had to learn to clot is based upon a rather flawed understanding of human physiology.

An excellent argument for ID.
