There are 13 different species of Darwin’s finches, and the slight variance of these species, which are believed to all be from the same ancestor, and their ability to adapt to the specific island of the Galapagos each call home is what helped Darwin hone his theories on evolution.

Why are animals in the Galapagos Islands Unique?
Animals on the Galapagos islands are unique because they have evolved without fear of humans. Most of the land animals endemic to these islands evolved without natural predators for millions of years.
How did the Galapagos Islands become so diverse?
Repeated volcanic eruptions helped to form the rugged mountain landscape of the Galápagos Islands. 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 animals in the Galapagos not afraid of humans?
Wildlife on the Galapagos Islands, the Natural Treasures of Ecuador. The Galapagos Islands are a group of volcanic islands in the Pacific Ocean, near the Equator.It is likely that due to the absence of predators on the islands, the animals of the Galapagos are not afraid of humans.
How were animals adapted on the Galapagos Islands?
Because there were no large predators on these two Galapagos Islands, having wings was a disadvantage that prevented them from finding food easily. They’re wings therefore adapted to be smaller while they developed powerful legs and webbed feet to dive into the water to hunt for fish, eels and small octopus.
Why is the Galapagos island important?
Facts. 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 are the Galapagos island called as an unusual place?
The author calls the Galapagos Islands ‘an unusual place’ because some of the endangered species of are found here.
Why the Galapagos Islands had high diversity of the sea animal?
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.
How many animals are on the Galapagos Islands?
Nearly 9,000 species are found on the islands and their surrounding waters, many of them endemic.
Are there pink iguanas?
Pink iguanas are not just a different colour from other land iguanas; they are a completely separate species. There are only around 200 left, and they are confined to the slopes of Wolf Volcano on Isabela, making them one of the most vulnerable species in Galapagos, as the volcano is still active.
Why there were no predators on the island?
According to the authors, Charles Darwin believed that escape behavior evolved to be lower where predators were rare or absent on remote islands because unnecessary escape responses are costly in terms of time and energy.
What animal lives in the Galapagos Islands?
Compared to the enormity of the Amazon Basin, Galapagos is a very small archipelago lost far out in the ocean. To give one illustration, the Amazon is home to over three hundred species of reptiles: Galapagos has only iguanas, tortoises, lava lizards, geckos and snakes.
What wildlife is in the Galapagos Islands?

How do animals survive on islands?
Floating is one way animals get to islands. They may float on their own or they may take a kind of raft. This raft is often made up of plants, branches, or other things that blow out into the sea during a storm and are swept together in the ocean. Flying helps animals like bats and bugs get to islands.
What animal characteristics were unique on the Galapagos?
- Blue-footed boobies. The name “booby” comes from a corruption of the Spanish bobo, which means “clown” or “fool.” Blue-footed boobies, then, get their name from two places: their bright blue feet and their remarkable clumsiness on land.
- Flightless cormorants.
- Sally Lightfoot crabs.
- Waved albatross.
What kind of animals did Charles Darwin discover on the Galapagos Islands?
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.
Does anyone live on Galapagos?
The Galapagos Population Today – Do people live on the Galapagos Islands. Currently, four islands are inhabited, with a total of around 30,000 inhabitants. The largest ethnic group is Ecuadorian Mestizos. In 1959, only 1,000 to 2,000 people lived on the islands, growing to 15,000 by the 1980s.
What’s wrong with 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.
Why are the Galapagos Islands so well suited for the study of evolution?
“Galápagos are a wonderful place to study evolution, still, because, remarkably, several islands and their inhabitants are close to being in the fully natural state, with little or no influence of human activities,” says the evolutionary biologist and Princeton University professor emeritus Peter Grant who, with his
Who discovered the Galapagos Islands?
Fray Tomás de Berlanga
In 1535, the Islands were officially discovered by Fray Tomás de Berlanga (the Bishop of Panama at the time). He was ordered to sail to Peru by Charles V to provide a report on activities there. He set sail from Panama on 23 February 1535. The strong ocean current carried him out to the Galapagos Islands.
Why did animals on the Galapagos Islands change over a long time?
Lamarck and Darwin agreed that animals change over time to adapt to their environment. For example, giraffe necks became longer over the course of thousands of years in order to allow them to eat leaves no other animal can reach.
