Fijian iguanas pose a conundrum to biologists: How did these lizards normally found in the Americas wind up thousands of ...

NEW YORK — Researchers have long wondered how iguanas got to Fiji, a collection of remote islands in the South Pacific. Most modern-day iguanas live in the Americas — thousands of miles and ...

By Asher Elbein For decades, the native iguanas of Fiji and Tonga have presented ... Spencer, an evolutionary geneticist at the University of Otago in New Zealand who was not involved in the ...

But new research suggests that millions of years ago, iguanas pulled off the 5,000 mile (8,000 kilometer) odyssey on a raft of floating vegetation — masses of uprooted trees and small plants.

these iguanas traveled nearly 5,000 miles (8,000 kilometers) — one-fifth of the Earth’s circumference — across the Pacific Ocean, eventually arriving in Fiji, according to a new study.

Understanding this type of water dispersal could offer new insights into how other species have colonized isolated areas over time, Scarpetta added. Iguanas have already demonstrated an ability to ...
