Toque macaque Toque macaque The toque macaque ("Macaca sinica") is a reddish-brown-coloured Old World monkey endemic to Sri Lanka, where it is known as the "rilewa" or "rilawa" (Sinhala රිළවා), (hence "rillow" in the "Oxford English Dictionary"). With age, the face of females turn slightly pink, prominent in the subsp. "sinica". "M. s. sinica" is found from the Vavuniya, Mannar, up to the lowlands of Anuradhapura, Polonnaruwa, Puttalam, and Kurunegala along the arid zone of Monaragala, and Hambantota districts. "M. s. aurifrons" can be found sympatrically with subsp. "sinica" within intermediate regions of the country, such as Kegalle, parts of Kurunegala. They
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,
