Summary:
- A new study suggests that iguanas found in Fiji originated from North America around 34 million years ago, challenging the previous belief that they arrived in Fiji from South America.
- Researchers analyzed DNA samples from Fijian iguanas and found that they are more closely related to North American iguanas than South American ones, indicating that they likely dispersed across the Pacific Ocean from North America.
- This finding provides insights into the biogeographical history of iguanas and highlights the complex patterns of species dispersal and evolution across the globe.
