How Iguanas obtained millions of years ago in North America
Genetic analysis shows that Fiji’s Iguana is closest to the lizard in the North American desert. How is this possible?
no way MercuryIn general, it is known as Iguana, the central Fiji band of Fiji Ovala Island.
Fijie Anas, with bright green scales and powder blue and white splins, look right from Fiji’s tropical island. But scientists have long been embarrassed by how this bulky lizard reached this remote place in the South Pacific.
A new analysis of iguana genetics published on Monday National Science Academy Procedure in the United States, It supports the hypotheses they impose Ripstems actually traveled to southwestern North America.-As more than 5,000 miles in one of the greatest marine Odyssey in nature.
Iguana sent a colonial island throughout the Caribbean and Galapagos Islands. However, either of these travels cannot be compared with Fiji Travel, which is more than 1,600 miles from Australia to east.

There was some It was speculated that the lizard arrived at the island through land bridges. Southern SUPERCONTINENET, gondwana, flintered. Others insisted that Iguana had a few months of sailing by floating on the “raft” of wooden branches and other debris or other debris in South America.
To learn more in new studies, researchers compared one of the four or species in the four. Bracket It is found with several species found in America in Fiji and Tonga. Genetic data showed that sebaceous reptiles are closest to Iguana in the inside. Dipsosaurus, He is an indigenous people in the southwestern North American desert, more than 5,000 miles away from Fiji.
Desert Iguana (Dipsosaurus Dorsalis).

Fijian Iguanas (some of them are extinct) and the close relationship between Desert Iguanas are the International Nature Conservation Union, which is not involved in new studies, or Christina de Jesus Villanueva, a member of an expert group. It was surprised. “A common ancestor between green Iguana [Iguana iguana] And Galápagos Marine Iguana [Amblyrhynchus cristatus] It would have been the first speculation as a predecessor of Figi Iguana.
According to the researchers of this study, Figi Iguanas has developed the most raping hypotheses by developing from 34 million to 33 million years ago, shortly after Gonde and Naga broke up. The vast open sea between North America and Fiji was able to cross the vegetation swept into the sea. Such sailing would be the longest marine dispersion by ground vertebrates known in science.
Simon Scarpetta, an evolutionary biologist at the University of San Francisco, says that research co -author Simon Scarpetta says that many iguana is resistant to heat and hunger due to slow metabolism and often crushed between the vegetation clump to the island. “If you need to think of a vertebrate group that can survive the rafting event in thousands of kilometers of a wide sea, Iguana is a great choice.”
