Strange evolution revealed now extinct monkey who settled in Jamaica until several hundred years ago – ScienceDaily


Ancient DNA's mysterious monkey Xenothrix analysis – which shows the bizarre body characteristics of any live monkey – has shown that it is the closest to the South American titi monkeys (Callicebinae). On their way to Jamaica, presumably due to vegetation, their bones were revealed to be the next best evolutionary change.

The study was published today Works of the National Academy of Sciences (November 12, 2018) and the London Nature History Museum (NHM) and American Museum of Natural History from New York Nature Charity ZSL (Zoological Society of London), as well as monkeys colonization of islands once again. The research reports an incredible discovery of how unusual ecology of the islands can significantly affect the animal's evolution.

XenothrixIn contrast to other monkeys, the relatively small teeth were the dwelling of the creeping tree, and the fig bones as the rodents. His unusual appearance is that scientists have difficulty working on what it was and how it developed. However, the scientific team has successfully acquired the first ancient DNA storm, which was revealed from the bones found in the Jamaican cave and created a significant new evolutionary view.

Professor Samuel Turvey from the ZSL, co-author of the paper, said: "This new understanding of evolutionary history Xenothrix It shows that evolution can take unexpected paths when the islands' islands are colonized and subject to new environments. However, extinction Xenothrix, Which developed on the island without native mammals, emphasizes the unique island biodiversity vulnerability before the human impact. "

Professor Ian Barnes, who works at the oldest DNA laboratory in NHM, says: "Over the last few years, we've been able to eradicate DNA from bone, but it's still difficult to tropical specimens where temperatures and moisture are destroyed by DNA very quickly. I'm excited That we could extract the DNA from these samples and overwrite it We have a complex history of Caribbean primates.

It is likely that XenothrixFrom South America, Jamaica's colonies are colonized 11 million years ago and probably after the pollution of the natural forests of the southern coast. Many other animals, such as the Great Rogue Hautia (Capromyidae), survive on some Caribbean islands, probably colonized like the region.

Natural history Mammography Division American Museum Ross makpeis study co-author, said: "Ancient DNA believes that the Jamaican monkey really only hay ape, which is unusual morphological features and is not new to the world in a completely different branch of evolution affect the island environment in unexpected ways, miniature elephants, Ki Artur Bird & Suites primitebit similar forms, examples of such an old cliche that "Anatomy of a mistress."

Რa Xenothrix It may seem as long as we have discussed the proposals that looked kinkajou (Potos) Or night monkeyAotus). Live titi monkeys are small tree-monkeys found across tropical South America, long soft, brown, gray or black fur. They are active during the day, in extremely territorial and vocals and in 12 years live in the wild, and the father often takes care of young people.

Although the Galapagos Islands are known to inspire Charles Darwin's theory of evolution, the Caribbean Islands have also used the most unusual and mysterious species ever developed. However, the Caribbean countries also suffered the highest risk of mammals extinction after the end of the glaciers of the last ice age, most likely due to the loss of hunting and habitat by humans and the preliminary detection of invasive mammals.
