Book Description
Excerpt from The American Naturalist, 1908, Vol. 42: A Monthly Journal Devoted to the Advancement of the Biological Sciences, With Special References to the Factors of Evolution There is some indication that the delay in the forma tion of the new leg in the frog is due to conditions exist ing in the bones or muscles and, as I have pointed out,1 it is significant to find that in the vertebrates the loss of power to regenerate a limb appears where cartilage has been changed to bone. The result is not however due directly to the ossification, since the new material is derived from the periosteum and not from differentiated tissue.
