KARYOLGICAL PECULIARITIES OF SPALACIDAE FAMILY (MAMMALIA: RODENTIA) SPECIES IN NORTH-IRAQ (KURDISTAN REGION)
Zaitoon Ahmad Hamad
Abstract: Spalacidae (Mole Rat) are highly adapted for life underground and have limited movement. Morphologically, they are cylindrical, powerful, heavy-bodied animals with short limbs and claws, and projecting incisors. Spalacidae occur in southeastern Europe, Asia Minor, the Caucasus and Transcaucasia; through the chernozem belt of the Russian plain to the Caspian, Syria, Palestine, Egypt and Libya. Spalacids are good model for speciation and explain to chromosomal variation in biology science especially evolution of living and to understand the inadequacy of morphologic species (typology) concept because of they have chromosomal polymorphism, sibling species and active speciation.
