New York (AP) – Researchers have long questioned how Iguanas reached Fiji, a group of remote islands in the South Pacific. most Iguanas modern era Living in the Americas – thousands of miles and one giant.
They thought they might hurry there across Asia or Australia before the Vie Feji’s volcanic activity pushed away.
But new research indicates that millions of years ago, Agwanas, 5,000 miles (8,000 km), launched a group of floating plants – blocks of uprooted trees and small plants. This trip is believed to record-farther from any other paragraphs preceding the lands that have ever traveled on the ocean.
Scientists believe this is how Iguanas has reached Galapagos Islands Supporting Ecuador and between the islands in the Caribbean Sea. Initially, they thought that Fiji might be very far from such a trip, but in a new study, researchers searched the genes of 14 types of Eguana that extend to the Americas, the Caribbean and Figi. They discovered that the Agwanas Vijian was closely linked to the desert Eiganas from North America, and that the two groups had separated about 31 million years ago.
The researchers created a statistical model using that and other stories about the place where IGuanas lives today and how they can spread. He suggested that Igoanna is likely to float to Fiji from North America.
“Given what we know now, their results are largely the most supportive,” said Kevin de Cueruz, an evolutionary biologist at the Smithsonian National Museum of Natural History, who did not participate in the new study.
The research was published on Monday in the Journal of the National Academy of Sciences.
It was possible that the trip from North America to Fiji would take a few months, but these desert universes would have got perfect passengers because they were drought resistance and could eat a snack.
“If you have to choose vertebrates to survive on a long journey on the ocean, it will be the Iguanas that will be what will be,” said study author Simon Scarpeta of the University of San Francisco, in an email.
The author of the study, Robert Fisher, of the United States’s geological survey, said that many types of fijian eguana are threatened with extinction, and Igwana Al -Akhdar Gazzi wanders on the islands today. To find out where these creatures came from scientists with tools to protect them better in the future.
