Fossils - 11 of 15

For your consideration...the following is an excerpt from a radio spot on KAPL radio, Jacksonville, Oregon, called " Akin For the Truth". To listen to the entire spot (a few minutes long), click the little microphone icon....Jack

Various similarities and differences found in fossil fishes and amphibians in limb structure, head attachment, elbow and knee joints, skull patterns and internal gills, are used to support the idea of transitional forms, attempting to obscure the line between the two classes. As we brought to light last time, however, the fact that there are very distinct skeletal differences between amphibians and fishes presents us with only one of the many problems encountered in trying to link fishes and amphibians. The internal organs...gills, ears, eyes, pelvic girdle, etc., are quite different also, and major changes would have had to occur in just the right order to accomplish the transition. But. alas, no "fishibian" has ever been found. Every fish, living or fossil, even those with unusual characteristics, is fully fish, and every amphibian, living or fossil, is fully amphibian.”
