THE MIRACLE OF THE

                       Dioxide
                       It's not only hemoglobin's oxygen-carrying ability that rep-
                   resents an insoluble dilemma for Darwinists. Hemoglobin also
                   possesses the ability to collect the carbon dioxide molecules
                   from the cells.
                       The transport of carbon dioxide in the blood is not as risky
                   as carrying oxygen. For that reason, red blood cells can carry
                   much larger quantities of carbon dioxide than they can of oxy-
                   gen. During rest, 100 milliliters of blood carries an average of 4
                   milliliters of carbon dioxide from the tissues to the lungs.
                   While the oxygen-carrying hemoglobin imparts a red color to
                   the blood, on its return to the lungs hemoglobin loaded with
                   carbon dioxide loses its bright color and assumes a dark red-
                   dish shade, akin to purple. That is why the veins close to the
                   skin surface appear dark red or even blue.
                       The blood generally carries carbon dioxide in the form of
                   carbonic acid. An average of only 5% is forwarded to the lungs
                   by binding itself to hemoglobin. Another 10% of carbon diox-
                   ide is in a dissolved gaseous state.
                       Carbon dioxide attaches to hemoglobin with a rather weak
                   bond. Once again, oxygen is the main factor at the stage of its
                   being released from hemoglobin. In this chemical phenome-
                   non, due to the hemoglobin's one particular property known
                   as the Haldane effect, when oxygen binds with hemoglobin,
                   carbon dioxide is released. When the tissues need oxygen, the
                    Haldane effect separates hemoglobin from oxygen and causes
                         it to bind more carbon dioxide. In the lungs, the same
                            property has an opposite effect. There, where the level
                             of oxygen is higher, oxygen behaves most expertly
