On the Galapagos Islands
Galápagos Islands
The Galápagos Islands, part of the Republic of Ecuador, are an archipelago of volcanic islands distributed on either side of the equator in the Pacific Ocean surrounding the centre of the Western Hemisphere, 906 km west of continental Ecuador. The islands are known for their large nu…
Finch
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwi…
What did Charles Darwin discovered at the galapangos Islands?
Charles Darwin’s Theory of Evolution. During Darwin’s expedition to the Galapagos aboard the HMS Beagle in the 1830s, he realized that certain animal species (finches for instance) were typically the same from one island to the next, but each one of them had succeeded in adapting to their specific environs in different ways.. One of the features that puzzled Darwin was the bird’s beaks.
Why did Darwin travel to the Galapagos?
Why did Charles Darwin go to the Galapagos Islands? Darwin theorized that the beaks were adaptations that helped each species of finch eat a different type of food, such as seeds, fruits, or insects. Darwin's study of the plants and animals of the Galapagos was integral to his theory of natural selection, a part of the larger process of evolution.
What did Darwin observe while studying finches?
One key observation Darwin made occurred while he was studying the specimens from the Galapagos Islands. He noticed the finches on the island were similar to the finches from the mainland, but each showed certain characteristics that helped them to gather food more easily in their specific habitat.
What did Darwin observe about species on islands?
Darwin suggested that the animals on the Galapagos Islands had become new species because they were adapting to new, local environments. Upon observing the 12 types of finches he encountered on the Galápagos Islands, Charles Darwin knew immediately that they were closely related.

What did Charles Darwin want to see in the Galapagos Islands?
Remember, Darwin was initially only interested in the island’s volcanoes, but it’s the unique flora and fauna that would leave a lasting impression on him.
What was Darwin's last destination before he reached the Galapagos Islands?
The last destination they checked out before reaching the Galapagos Islands was Chile. Here, Darwin saw a powerful earthquake that awarded him the chance to witness the uplifting of the layers.
What was Darwin's second island?
The second Island he explored aboard the Beagle was Floreana. At Floreana, Darwin had the opportunity to gather species and collect the second bird that would lead to his important conclusions later on. This bird was the Floreana Mockingbird. The third island was Isabela, and he went there on September 29 th, 1835.
What islands did the Beagle explore?
Here, he carefully studied how the lava flows then went on to theorize about its formation. The second Island he explored aboard the Beagle was Floreana.
What did Darwin learn from the mountainous regions of Peru?
This, coupled with the marine evidence that he came across in the mountainous regions of Peru, led Darwin to better understand that geological uplifting and movements usually result in the formation of coral reefs and sinking of islands.
What were the first specimens Darwin collected?
The first specimens Darwin collected were plankton and marine invertebrates that he found on the boat. Captain Fitzroy’s mission, on the other hand, was to create accurate maps and charts of the region since new trade relations were being established with South America and the coastline was uncharted at the time.
How many species of birds are there in the Galapagos Islands?
Today, there are 26 species of birds native to the Galapagos Islands and 14 of them make up the cluster known as Darwin’s Finches. This group of birds is also considered one of the fastest evolving vertebrates in the world.
Where did Darwin discover the Galápagos?
Discovering wildlife never seen before. After circling San Cristóbal, Darwin's journey continued along Santa Cruz (the unofficial capital of the islands), Santa Fe (which is home to its own breed of Galápagos Giant Tortoise ), Floreana (home of the first person to live in the Galápagos full time) and around the southern end of Isabela.
How long did Darwin spend in the Galápagos?
Darwin spent a total of five weeks in the Galápagos, collecting animals, plants, rocks, and data. Interestingly, it was only after he returned to Cambridge that he realized the significance of the specimen he had caught and proceeded to examine them further. Together with his observations regarding the different types of Galápagos tortoises and the help of John Gould, who identified his birds, Darwin was able to form his theories. After presenting his revolutionary findings to the Zoological Society of London, his story made the newspapers. Darwin subsequently published his diaries from the voyage on the HMS Beagle to give further insight into his studies. By the time the first edition of The Voyage of the Beagle was published, he had already started working on further publications on his theory of evolution and natural selection.
Why did Charles Darwin publish his diaries?
After presenting his revolutionary findings to the Zoological Society of London, his story made the newspapers. Darwin subsequently published his diaries from the voyage on the HMS Beagle to give further insight into his studies.
Where did Charles Darwin first set foot?
Darwin probably first set foot on Galápagos in San Cristóbal where he arrived in 1835. This is also where he observed and caught the first specimen of finches and other birds to support his theory of evolution. During the course of his travels, Darwin collected a variety of larger animals, birds, and insects, as well as plants ...
What did Darwin collect during his travels?
During the course of his travels, Darwin collected a variety of larger animals, birds, and insects, as well as plants and rocks to study them further and bring them back with him.
Where did Darwin find finches?
While the finches Darwin collected from Santiago and San Cristóbal, which are in relatively close proximity to each other, were rather similar, the ones he found on Floreana and Isabela differed from each other significantly.
Where did the HMS Beagle sail?
After spending some time on Isabela, the HMS Beagle set sail again and headed towards some of the most remote islands of the Galápagos: Pinta (the original home of the famous Lonesome George ), Genovesa (formed from the collapse of a volcanic crater), and Marchena (to this day the least visited island).
