Iguanas on Fiji's remote island may seem to have a cold life. But from the new research that they have to work for it: by floating over the ocean thousand miles on plants in the past 30 million years
The new investigation of the IGUANIDAE family – 2,100 types of trees from Iguanas from the sea of Galapagos to the tropical chamelers of the desert – indicate that Fiji Iguanas has a close relationship with the beast.
When considering the geographical distance between the two But their genetic intimacy, the researchers, concluded that in the past, ancient desert reptiles that were bound to sit on the fragments and never look back to -millions of the research of the team, namely Published Today in the implementation of the National Academy of Sciences
“Iguanas descent is separated from their sister's descent. Not long ago, close to 30 million years ago, whether ETT, San Francisco University and the author of the newspaper at the University of California Burtil release–
“The mechanism that is likely to spread is a rafting on a plant mat, so Igaa traveled from North America to Fiji. There may be food from the raft to travel across the Pacific Ocean.” Scarpetta told GizModo via email. ” Said that the previous estimates for traveling across the Pacific Ocean are between 4 and 12 months, although the latest simulation will introduce a duration of 2.5 to 4 months.
If the conclusion of the team is correct, Fiji's ancestors, Iguanas Schlepped, 5,000 miles (8,047 miles) from North America to Fiji, riding horses, plants in the ocean and dreams. Traveling is the longest Transoceanic of the on-sights.-Specific records. But one thing that talks about the excellent nature of finding
“In particular, Igua and the desert are resistant to starvation and dehydration. Therefore, my thoughts are if there are any spine or lizards groups that can travel 8,000 kilometers throughout the Pacific Ocean. The ancestors will be one, “said Scarpetta.
The genetic analysis of genes ikua is more than 4,000 genes taken from more than 200 samples of lizards, revealing the close relatives of Fiji Eguana: The desert in North America.Dipsosaurus Dorsalis–
Due to the islands of Fiji for about 34 million years ago and depends on the genetic differences of Fiji Iganas from the desert in the desert in North America. The researchers thought that the lizard had arrived in the island in the past 30 million years.
“They arrived directly from North America. It seemed to be crazy,” Jimmy McGuire, the author of UC Berkeley, said in the same launch, “but the alternatives related to colonies from the adjacent country. They arrived in Fijip in 34 million years ago or more. “
The idea that Iguanas floated from other places to the islands of the South Pacific Ocean. Floating– But the new research is effective in South America's original rule for Pacific Iguanas, as well as the idea that repreted from the old lineage that is previously widespread in the Pacific Ocean before extinction.
“One of the worthwhile questions that point out about our studies, although it is difficult to test, is that Iguanas jumps over the island in the Pacific Ocean from North America to Fiji or not instead of rafting in one event,” SCARPETTA added. “This is an interesting possibility, even though there is no fossil of Fiji Ekana, known from anywhere in the Pacific Fiji and Tongka, and the volcanic islands, or many places in the Pacific Ocean”.
Even being lonely on a remote island But the four -breed Igua on Fiji and Tongka are endangered due to the loss of housing, robbery, and exotic pet trade. The new research is a warning of the pain of living things that have to suffer for survival and give us another reason for the preservation of animals that have been done to this day.
