The evidence for bone evolution from some nonbone substance was reviewed, concluding that all of the bone evolution proposals have been falsified. In the words of one researcher, bone magically appeared in life and left no trace of its evolution, even though bone and teeth are one of the materials that have the best record of preservation of all biomaterial in the fossil record. Bone is one of the most complex organs in the body and, if it evolved, there would be clear evidence of its evolution. The evolution theories proposed to explain bone evolution were also examined in some detail, showing they were all very problematic.
