The mere arrival of an organism to the Galapagos Islands is just one piece of the early survival puzzle. The Templeton Crocker Expedition spent two months in the islands in 1932, and the Academy of Natural Sciences of Philadelphia made two expeditions, in 1936 and 1937, to the islands, with the support of Dennison Crockett on the Chiva and George Vanderbilt on the Cressida. To top off the astounding fauna, Galapagos islands plants are just as mind-blowing. With this theory, he, once again, used the Galapagos Islands to explain and prove his concept.

His social upbringing granted him a comfortable life and finally the chance of traveling with Captain Fitzroy, aboard the HMS Beagle. This raft theory of arrival also explains why there are no native amphibians, few mammals, and many reptiles in the Galapagos Islands reptiles are the best adapted to deal with the harsh salty and sunny conditions of weeks at sea.
