DNA analysis indicates that the species is a type of titi monkey, sister to the recently recognized northern South American genus Cheracebus, that colonized Jamaica around 11 million years ago. This is younger than the oldest fossils of monkeys on Cuba, meaning that the Jamaican monkey has a separate origin from the other monkeys of the Greater ...
A 2018 DNA study of the Jamaican monkey suggested that it diverged from its closest relative Cheracebus around 11 Ma, during the Late Miocene, which is younger than the 18 Ma Paralouatta from Cuba, meaning that the Jamaican monkey has a separate origin from the rest of the Antillean monkeys, making the group polyphyletic.

The species could have suffered from hurricanes devastating its mountain forest refugia in 1899, 1924, and 1929, and inability to recover in the lowlands due to deforestation for agriculture, competition with the Lesser Antillean bullfinch, and predation by introduced rats, cats, small Indian mongooses, and green monkeys.
The Chimpanzee Genome Project was an effort to determine the DNA sequence of the chimpanzee genome. Sequencing began in 2005 and by 2013 twenty-four individual chimpanzees had been sequenced. This project was folded into the Great Ape Genome Project. [1] Two juvenile central chimpanzees, the nominate subspecies

Scientists based in China have created a monkey chimera with two sets of DNA, experimental work they say could ultimately benefit medical research and the conservation of endangered species.
Jamaican monkey, X. mcgregori EX; Order: Rodentia (rodents) Rodents make up the largest order of mammals, with over 40% of mammalian species.
