I Therapsid Reptiles a. As I have come to understand the argument, the Evolutionist claims that the lower jaw and the three ear bones of canine mammals evolved from the lower jaw of therapsid reptiles. LOWER JAW of the therapsid reptile has 6 bones on the right side of the face and six bones on the left side of the face. The LOWER JAW of Canine mammals (dogs, wolves etc.) has only one bone on each side of the face. Also, therapsid reptiles have ONE EAR BONE between the drum and inner ear, whereas canine mammals have THREE EAR BONES. Finally, the jaw joint for the therapsid reptiles hinges at a different part of the skull than the canine jaw does. Compared side by side it looks like this: Canine mammals: three ear bones go from the drum to inner ear Therapsid reptiles: one ear bone goes from drum to inner ear Canine mammals: lower jaw is one bone on each side of face Therapsid reptiles: lower jaw is six bones on each side of face Canine Mammals: lower jaw hinges with the skull at the squamosal area Therapsid reptiles: lower jaw hinges with the skull at the quadrate bone. A bone not found in mammals. c. Now, Evolutionists believe that the many jaw bones of the reptile (the small bones near the hinge) evolved into the three ear bones of the mammal (jaw bones evolved into ear bones). And, the reason canines only have one jaw bone is because the "other jaw bones" are now evolved into their ear (six jaw bones evolved into one jaw bone). And the reason the jaw bone has "moved" to a new hinge is due to some of the bones shifting into the ear. d. On the face of it it sounds quite incredulous. In fact, one school text book which taught evolution put it this way: "Of course, there are numerous unresolved questions about this story; for example, how did [they] hear, and chew while these fantastic changes were taking place? But, despite such functional problems there is little doubt that it happened." e. Now the evidence against these changes come from a simple consideration of what the transformation would require. The hinge would have to shift to a new location, five bones of the lower jaw would have to break away from the largest bone. The top of the jaw bone ( up where the hinge was) would have to force its way into the middle ear and form itself into an entirely new kind of hearing mechanism. While all this was happening two NEW complicated structures would have to develop in the inner ear simultaneously, the organ of Corti and the vestibular component of balance. f. The organ of Corti, peculiar to mammals, comprises some 3000 arches placed side by side so as to form a tunnel, and along with its nervous connections it makes for a tremendously complex formation. Add to this the vestibular component of balance, which includes the semi-circular canals in planes at right angles to each other, and you have plenty of reason to doubt evolution could have effected such changes. g. In other words I doubt seriously that the skulls offered by evolutionists as intermediate transitions are correctly interpreted. But, at the same time I have no affirmative explanation to offer for them. So although I am unsure as to what they are I am more sure as to what they are not. h. I think you could appreciate my doubts a little better if you were to imagine what would happen to your interpretation if a fully developed mammal jaw was discovered at a level lower than the fossils it was supposed to have evolved from. If that were to occur it would prove these fossils had not been transitional to start with, and the entire interpretation would have to be reworked. My point? I feel the interpretation could be reworked with little difficulty. i. Creationists have a more scientific argument, however. They argue that a modern understanding of genetics would make your interpretation impossible. In view of the fact generations upon generations of fruit flies and e-coli bacteria have been interbreeded, isolated, bombarded with radiation and exposed to diverse heat and cold environments, the lab has been unable to get any thing to evolve except fruit flies, and ecoli bacteria! It is true that micro evolutionary changes are brought about, but in no case is a macro evolutionary change achieved. Fruit flies beget fruit flies and ecoli begets ecoli. Apply that principle to your fossils and you have good reason to doubt they could be a bridge between reptiles and mammals. j. For the evolutionist the entire argument rests upon a similarity in structure. But, Creationists point out that similarities (homologies) are known to develop independently. Here I quote one such example: "An edifice of presumed relationships has been built up from the careful study of homologous structures-not least from the study of bones in the skull of reptiles. However, does such study still support evolution? Recently a bone in the floor of the skull that lies between the eyes of amphisbaenian lizards has been causing trouble. In other lizards this bone, the orbitosphenoid, is formed in the normal way from a cartilaginous precursor. It was presumed that this also occurred in amphisbaenians and that the bones unusual thickness was an adaptation to their burrowing habit. Now it has been found out it develops in the embryo in quite a different way-from soft tissue instead of cartilage. Because of this it fails the test of homology, although it completely mimics `normal' orbitosphenoid bones in other lizards. Does it derive from a similar genotype? Could this kind of phenomenon have been more widespread than previously believed? An anatomist, Dr R. Presley of University College, Cardiff, has written: `...this apparently obscure finding seems to me in light of my present knowledge of the subject to have shaken the philosophical and logical framework of comparative biology to a very serious extent, and lots of people ought to be worried by it. I bet they aren't" (Adam and Evolution pg 41,42 by Michael Pitman) II. What, you want me to wait ANOTHER few hundred years? You will find I answered that argument before you even made it. In message 67 item 4 I pointed out that millions of years had already gone by. Nascent organs and appendages ought to be emerging even now. Yet they are not. To say that the right conditions haven't occurred yet requires us to reject the evidence before our own eyes in favor of a secondary assumption. III. Is Evolution Testable? I made two comments in message 67 regarding the non-testability of Macro Evolution. First, I pointed out it did not fall into the same realm of testable science as does the theory of electricity or the theory of gravity. I then went on to compare it to a forensic science which reconstructs circumstantial evidence. It is not testable because it can not be demonstrated in the lab or directly observed. The fruit fly and e-coli experiments have failed to produce a macro evolutionary change and the whole theory is over burdened with hypothesis. It is not testably proven. Second, I said that Macro Evolution was not falsifiable. I feel you have answered this second statement quite well. Your point about the man tracks was well taken, and my own point about what would happen if a mammal fossil was found falls in line with your argument. In other words Evolution is theoretically falsifiable and I concede that point to you. However, Creationism falls into the same category. I think you are equally in a position to admit that Creationism is falsifiable. It could be falsified if macroevolution ever resulted from the fruit fly experiments or if a living example of macro evolution occurred today, or if a fossil was discovered which removed all reasonable doubt. IN Summary I think the evidence you offer falls considerably short of what I had in mind as a transitional form. However, I see why you regard it as transitional. I pointed out though that your evidence does contain a hypothetical element that could be reinterpreted. I also pointed out that modern genetic theory as evidenced in the fruit fly experiments would indicate your interpretation had to be wrong. Also, the fact that homologies (similar structures) are capable of independent formation would cast reasonable doubt on your interpretation as well. You ask me to wait another few hundred years, but the millions that I have waited should be enough. Nascent organs and appendages should be emerging today, but none are. Evolution is overburdened with hypothesis. Evolution is a forensic science, and is not testably proven. However, it is theoretically falsifiable, but then again Creationism is also. Arminius2
