The current Galapagos Islands are a volcanic island chain which formed around 4 million years ago. However, there have been islands, forming and being slowly destroyed, for over 80 million years. Scientists have found evidence of this in submerged seamounts. This constant creation of new islands is due to a suspected plume of hotter material under the crust, similar to the one which formed the Hawaiian islands. Thus, animal life could have been migrating to and evolving on these islands for close to 80 million years.
