American biologists from the University of California in Berkeley and the University of Southern Florida found an incredible journey of about 8,000 kilometers long from North America to Fiji and Tonga Islands. This is the longest famous transocean re -settlement among the terrestrial vertebrates. The study was published scientifically magazine National Academy of Sciences (PNA) procedures.
Experts carried out a genetic analysis that shows that Fiji Iguans (Brachylophus genus) was the closest relatives of the North American Desert Iguan (Dopsosaurus). His lines were divided about 34 million years ago, which coincided with the formation of Fiji’s volcanic islands.
Scientists believe that about 34 million years ago, the Iguans overcome the Pacific Ocean in pieces of trees that float. This improvisation shakes can provide reptiles to food and protection during a long journey. The stability of hunger and dehydration made them ideal candidates for such a risky initiative.
“You can imagine how the cyclone, iguans or eggs fall into the trees where the cyclone, iguans or eggs fall into the new shores,” he said.
Previously, scientists suggested that Fiji iguans could come from South America or could be part of a common line around the Pacific Ocean. However, the genetic analysis conducted by Scarpetta and his colleagues excluded these hypotheses and confirmed the connection with the North American desert iguans.
Biologists added that Fiji iguans is the only representative of the Iguan family in the western part of the Pacific Ocean, which made them a unique example for the settlement.
