The Galapagos Islands are uniquely located on both sides of the equator in both the Northern and Southern Hemispheres. The islands are situated at a point in the Pacific Ocean where three ocean currents collide, creating a unique area in the sea where warm and varying degrees of cold water meet.

What makes Galapagos Islands special?
The Galápagos Islands are a chain of islands, or archipelago, in the eastern Pacific Ocean. They are part of the country of Ecuador, in South America.The Galápagos are best known for their diverse array of plant and animal species. Many species are endemic, which means they are not found anywhere else in the world.
Why are the Galapagos Islands so important and unique?
Six hundred miles off the coast of Ecuador lie the volcanic islands of the Galápagos, famous for a wealth of unique plants and animals found nowhere else in the world. The Galápagos Islands were the source of Darwin’s theory of evolution and remain a priceless living laboratory for scientists today.
Why do the Galapagos Islands have so many unique species?
The Galapagos Islands are home to a wide range of species ranging from the iconic giant tortoises to lesser known plant and bug life that are often hidden away in the hard-to-reach areas. The Galapagos Islands are so biodiverse because of the many different habitat zones that can be found across the Islands.
Why do islands have unique species?
An island, especially a remote one, may be colonised by relatively few species. This allows the members of one species to exploit numerous different lifestyles, or ‘niches’ – a phenomenon called adaptive radiation. As the individual groups adapt to their different niches, they may evolve into distinct species.
Why are the Galapagos Islands important to the theory of evolution?
His discoveries on the islands were paramount to the development of his Theory of Evolution by Natural Selection. On the islands, Charles Darwin discovered several species of finches. Thanks to his close observations, he discovered that the different species of finches varied from island to island.
What do scientists say makes the Galapagos Islands unique quizlet?
What makes the Galapagos Islands unique? The animals that live there have evolved there and nowhere else and the huge crosss-section and diversity of life.
Why is it important to save the Galapagos Islands?
The Galapagos Islands are a fragile environment, easily affected by weather phenomena and sudden changes in the world’s patterns that make us realize how all our actions are inextricably connected. To care about and protect the Galapagos means to care about and protect the world’s threatened environments and resources.
Why does it matter what is happening to the Galapagos Islands?
The Galapagos Islands face many environmental threats. Ecosystem degradation could be caused by: climate change, deforestation, pollution, overfishing, eutrophication and the introduction of invasive species.
What is Galapagos Islands known for?
Six hundred miles off the coast of Ecuador lies the Galápagos Archipelago: a world unto itself, forged of lava and isolated for thousands of years. The islands are known for their famously fearless wildlife and as a source of inspiration for Darwin’s theory of evolution.

- Any time is a great time to visit.
What is unique about islands?
Islands seem to have it all: ample sunshine, white sand beaches, and species you can’t find anywhere else on Earth.They predicted that islands closest to the mainland would be the least unique and that the islands with the highest biodiversity would have been separate from the mainland for the longest period of time.
Do islands have unique species?
Islands boast some of the most diverse collections of plants and animals on Earth. With a unique set of influences and conditions, island life has evolved very differently from life on larger landmasses. Islands preserve habitats for a wealth of unique and endemic plants and animals on land and in the water.
Why do islands tend to have unique animals on them and make great study areas for natural selection?
A higher level of species turnover on islands indicates that islands had more unique species than similar-sized areas of the mainland.This meant that that the species on two islands were more likely to be different from each other than were the species in two mainland samples.
Why did Darwin choose the Galapagos Islands?
Charles Darwin in the Galapagos.During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands’ inhabitants.
Why are the Galapagos finches beaks different from each other?
In other words, beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti. Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits. Shorter, stouter beaks served best for eating seeds found on the ground.
How do the Galapagos Islands clearly demonstrate natural selection?
Studies of Natural Selection After Darwin
The Grants found changes from one generation to the next in the beak shapes of the medium ground finches on the Galápagos island of Daphne Major.This was clear evidence for natural selection of bill size caused by the availability of seeds.
Are the Galapagos Islands similar to each other?
The individual Galapagos Islands are all similar to each other. Malthus argued that human populations grow faster than their resources. Lamarck was one of the first scientists to propose that species evolve by natural selection.According to Darwin, natural selection is what occurs, and evolution is how it happens.
What are the Galapagos Islands known for having giant?
Located 906 km (563 mi) west of continental Ecuador, the islands are known for their large number of endemic species that were studied by Charles Darwin during the second voyage of HMS Beagle. His observations and collections contributed to the inception of Darwin’s theory of evolution by means of natural selection.
Why do Galapagos tortoises have different shells?
The iconic giant tortoise of the Galapagos Islands has a strange shell to help it get back on its feet when it flips over on the rocky islands, according to new research. It was thought that the weird shell, shaped like a saddle, was to enable it to reach higher vegetation, such as cactus.
What is the Galapagos special law?
The Special Law is a lengthy piece of legislation passed by the Ecuadorian government in March of 1998.The constitution of the Ecuadorian Republic grants permission for Galápagos to be run by a Special Regime, and for its protection, the rights of free residence, property, and commerce can be restricted.
