Ancient monkeys are being developed to resemble slack after arriving at Jamaica – About 10 million years ago, a group of Apafamilians left South America and sailed to Jamaica. Arriving there, the life of the old monkey changed dramatically, they resembled lazy nonsense.

For generations, the legs became slower when climbing tropical trees. Then the molar teeth or moles become larger so the other teeth become smaller. This group of primates spends more of the rest of the day on the tree, making it more like a lazy sloth than a monkey.

This strange Jamaican slothapa is better known as Xenothrix mcgregori, They are really real and have been extinct since 900 years ago.

There is nothing to deny that this group of primates is the strangest ever lived in the Western Hemisphere. But what's still a puzzle is that took them to Jamaica and what their ancestors really were.

Now, a new study published in the newspaper Negotiations by the National Academy of SciencesOn Monday (11/12/2018), which gave the first proof that grandmother retrieved X. mcgregori From Jamaica, there may be an explorer native to South America.

The new study of the International Zoological Team from the United States analyzed two-legged DNA samples X. mcgregori which lived about 1500 years ago.

With the help of the Natural History Museum at Antigens DNA Laboratory, experts survey the genome X. mcgregori and compare it with Caribbean primates and other monkeys still living in the mainland of South America.

As reported Live ScienceOn Tuesday (11/13/2018), the analysis showed that the closest relatives X. mcgregori is a subfamily of South American primates called Titi Monkeys (Callicebinae). Titi monkeys are an active and flexible group of small monkeys, living in many forests in South America.

"Ancient DNA shows that the Jamaican King of Kangaroo is actually a titiapa with some unusual morphological characteristics. It's not a completely different new monkey," says co-author Ross MacPhee of the American Museum of Natural History Department of Mammalogy.

"Evolution can work unexpectedly in the environment, for example producing miniature elephants, giant birds, and no exception for primitive primates," he added.

In his report, experts suspect monkeys and X. mcgregori developed about 11 million years ago.

Earlier, Jamaica and South America separated the sea. Chances are that the group of monkeys accidentally sailed using a "fleet" of vegetation that came out of a large river in South America until it finally stranded in Jamaica.

When they arrived in Jamaica and started colonizing the area, they adapted to the new environment for several million years until finally extinct due to human existence.

"eradication X. mcgregori developed on an island without domestic predators, emphasizes the great vulnerability of the unique biodiversity in the face of human presence, says study writer Samuel Truvey of the Zoological Society of London.

In this case X. mcgregori maybe not alone. The remains of fossils of other unique Caribbean apheres that were up to 18.5 million years ago indicate the presence of several groups of "colonizing" primates landing on different Caribbean islands for centuries.
