How did tortoises get to the Galapagos Islands?

Answer 1

These special Birds called "Darwin's or Galapagos Finches" have special adaptations to various habitats were important evidence considered by Charles Darwin in formulating the theory of evolution; they are a striking example of adaptive radiation. They evolved because of their surroundings, the beaks their ancestors had couldn't function properly on the island.

Answer 2

Giant tortoises, up to 5 feet in length, were widespread on all continents except Australia and Antarctica before and during the Pleistocene .Now extinct from large landmasses, giant tortoises have persisted through historical times only on remote oceanic islands: the Galápagos, Seychelles, and Mascarenes. The tortoises of the Mascarenes are now extinct; the last animal died in 1804. The tortoises of the Seychelles are represented by a single surviving population on the Aldabra atoll. Only in the Galápagos have distinct populations survived in multiple localities. The Galápagos tortoises remain the largest living tortoises (up to 400 kg) and belong to a pantropical genus of some 21 species. The Galápagos tortoises most likeely floated from the beaches of the mainland.

Answer 3

Five to ten million years ago, the tops of underwater Galapagos volcanoes appeared above water for the first time about 600 km from mainland Ecuador in the middle of the Pacific Ocean. Those volcanic peaks were completely devoid of plant and animal life. All plants and animals that are now native to the islands must have arrived to the islands originally through some form of long-distance dispersal.

When considering the diversity of species that do inhabit the Galapagos Islands, it is important to note how "unbalanced," in comparison to continental species diversity, the variety of Galapagos species are. For instance, there are many native reptile species, but no amphibians; there is an abundance of land and sea bird species, but very few mammals. When considering plants, those with large flowers and big seeds are absent while grasses and ferns abound.

There are two main ways for species to make their way to remote islands (aside from any methods involving humans). The first method is by air in the form of flying or being blown by wind, and the second method is by sea while swimming or floating, sometimes with the aid of rafts of tangled vegetation What ever now these animals are being points of attractions for tourist who are comes here for enjoy the Galapagos wildlife under touring guide as Ecuadorgreentravel.net

Answer 4

Charles Darwin studied animals on the Galapagos Islands. One of the animals he studied was finches. As Darwin studied the finches he concluded a theory that the Galapagos finches were descendants of South American finches, blown to the Galapagos Islands by a huge storm. The finches them adapted to the environment and thrive there today ~

Answer 5

Probably by rafting (for the smaller species and the iguanas) floating (turtles; yes, they float, and can stay alive without food or water for very long) or just flying (birds, bats, insects, could be aided by a storm).

Bear in mind the Galapagos are volcanic, and on the one end islands are emerging anew while they disappear under the sea on the other end. Rafting, floating and flying are continually going on (in evolutionary time) to keep the archipelago inhabited!

Answer 6

animals got there by sturdy rafts made of plants.

Answer 7

it was a sea animal first then went on to land then spent more time
