Bonnet macaque Bonnet macaque The bonnet macaque also known as zati ("Macaca radiata") is a macaque endemic to southern India. Its distribution is limited by the Indian Ocean on three sides and the Godavari and Tapti Rivers along with a related competing species of rhesus macaque in the north. Land use changes in the last few decades have resulted in changes in its distribution boundaries with the rhesus macaque, raising concern for its status in the wild. This Old World monkey is a diurnal animal. It is 35–60 cm long plus a tail of 35–68 cm. Males weigh 5.5 to 9.0 kg,
Rhesus macaque from the common ancestors of the primate clade to "Homo sapiens"," said Bruce Lahn, University of Chicago. After the human and chimpanzee genomes were sequenced and compared, it was usually impossible to tell whether differences were the result of the human or chimpanzee gene changing from the common ancestor. After the rhesus macaque genome was sequenced, three genes could be compared. If two genes were the same, they were presumed to be the original gene. The chimpanzee and human genome diverged 6 million years ago. They have 98% identity and many conserved regulatory regions. Comparing the macaque and human genomes,
