The story that iguanas tell

So most of us know that the islands of the Pacific are either volcanoes that emerged from the ocean floor or atolls of ancient coral. I did not know until today that two of them, however, formed in a completely different way. Tonga and Fiji were actually part of an ancient supercontinent, which is now submerged except for them. And lizards help provide the evidence!
