“Platelets” play an important role in preventing the loss of blood by beginning a chain reaction that results in blood clotting. As blood begins to flow from a cut or scratch, platelets respond to help the blood clot and to stop the bleeding after a short time.
Platelets promote the clotting process by clumping together and forming a plug at the site of a wound and then releasing proteins called “clotting factors.” These proteins start a series of chemical reactions that are extremely complicated. Every step of the clotting must go smoothly if a clot is to form. If one of the clotting factors is missing or defective, the clotting process does not work. A serious genetic disorder known as “hemophilia” results from a defect in one of the clotting factor genes. Because they lack one of the clotting factors, hemophilia sufferers may bleed uncontrollably from even small cuts or scrapes.
To form a blood clot there must be twelve specific individual chemical reactions in our blood. If evolution is true, and if this 12-step process didn’t happen in the first generation (i.e., if any one of these specific reactions failed to operate in their exact reaction and order), no creatures would have survived. They all would have bled to death!
