Blind mole rat (Spalax ehrenbergi). [1] The hystricognath mole-rats of the family Bathyergidae are completely unrelated, but some other forms are also in the family Spalacidae. This study investigates the causal chain of dorsal coloration in Israeli subterranean blind mole rats, Spalax ehrenbergi. The four Israeli allospecies climatically and adaptively radiated into the cooler, mesic northern domain (N) and warmer, xeric southern domain (S). One study showed that in adaptation to a higher tendency of cell death, blind mole rats evolved a mutation in the tumor suppressor protein p53, also used in humans, to prevent cells from undergoing apoptosis. Blind mole rats may have evolved from spalacids that used their front limbs to dig, because their olecranon processes are relatively large relative to the rest of their arms. It is found in Russia and Ukraine. The olecranon process is a part of the ulna bone where muscles attach, and digging animals tend to have enlarged olecranon processes to provide a large surface for their large and powerful muscles to attach.
