Recent scientific findings indicate that iguanas, a group of reptiles now found in various parts of the world, may have achieved an extraordinary feat of natural dispersal tens of millions of years ago. According to the research, some iguanas originating in North America are believed to have crossed the Pacific Ocean around 30 million years ago. The proposed method of travel was rafting: the iguanas likely clung to mats of vegetation or debris that were swept out to sea, possibly by storms or floods. This journey would have spanned about 8,000 kilometers, roughly one-fifth of the Earth's circumference, making it the longest documented ocean crossing by a flightless land vertebrate. The study is based on genetic analysis and fossil evidence, which suggest that the ancestors of certain iguana species found on Pacific islands share a common lineage with North American iguanas. This discovery provides new insights into the distribution and evolutionary history of iguanas, as well as the broader mechanisms by which animals can colonize distant lands. Such long-distance dispersal events, while rare, have played a significant role in shaping the biodiversity of isolated regions around the world.
