Evolutionary History
Researchers theorize that land iguanas and marine iguanas evolved from a common ancestor since arriving on the islands from South America, presumably by rafting. It is thought that the ancestral species inhabited a part of the volcanic archipelago that is now submerged. The two species remain mutually fertile, and occasionally hybridize where their ranges overlap.
