Barbary macaque this monkey are longer than its hind limbs. Females are smaller than males. The Barbary macaque is mainly found in the Atlas and Rif Mountain ranges of Morocco and Algeria. It is the only species of macaque that is distributed outside Asia. These animals can occupy a variety of habitats, such as cedar, fir, and oak forests, or grasslands, scrub, rocky ridges full of vegetation. Most Barbary macaques inhabit cedar forests currently in the Atlas Mountains, however, this could reflect the present habitat availability rather than a specific preference for this habitat. The diet of a Barbary macaque consists of
Rhesus macaque significance because the macaque is used as an experimental model of the human immune system. In humans, the preferentially expressed antigen of melanoma (PRAME) gene family is expanded. It is actively expressed in cancers, but normally is testis-specific, possibly involved in spermatogenesis. The PRAME family has 26 members on human chromosome 1. In the macaque, it has eight, and has been very simple and stable for millions of years. The PRAME family arose in translocations in the common mouse-primate ancestor 85 million years ago, and is expanded on mouse chromosome 4. DNA microarrays are used in macaque research. For example,
