What did Darwin collect on the Galapagos Islands?
During his time on the islands, Darwin was not aware of the importance the archipelago had as evidence for his theory, and he still had no clue of the information he was gathering on each excursion. He collected lots of reptiles, plants, and birds among which were the famous Darwin finches.
What did Darwin discover?
natural selection
With Darwin’s discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science. The adaptive features of organisms could now be explained, like the phenomena of the inanimate world, as the result of natural processes, without recourse to an Intelligent Designer.
How did Darwin think plants and animals had originally come to the Galapagos Islands?
Charles Darwin Galapagos Adventure
The inspiration brought by Galapagos came through these voyages in the HMS Beagle:The Beagle itself was far too large to land, so it cruised around the islands and smaller boats would take Darwin and the other crew members ashore, where they could mingle with the endemic wildlife.
How did Darwin find the Galapagos?
Darwin first went ashore in Galapagos on September 18, while the crew captured several San Cristobal giant tortoises for food. Darwin was intrigued by the tortoises and collected a handful of plant specimens. Darwin was impressed by the rocky island and the lava that formed it.
What animals did Darwin see on his voyage?
Darwin noticed that the plants and animals on the different islands also differed. For example, the giant tortoises on one island had saddle-shaped shells, while those on another island had dome-shaped shells (see Figure below). People who lived on the islands could even tell the island a turtle came from by its shell.
What did Darwin discover about Galápagos tortoises?
Darwin noticed that different tortoise species lived on islands with different environments. He realized that the tortoises had traits that allowed them to live in their particular environments. For example, tortoises that ate plants near the ground had rounded shells and shorter necks.
What was Darwin famous for?
British naturalist Charles Darwin is credited for the theory of natural selection. While he is indeed most famous, Alfred Wallace, simultaneously came to a similar conclusion and the two corresponded on the topic. Charles Darwin was born in 1809 in Shrewsbury, England.
How did animals get to Galapagos Islands?
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.
How many animals did Charles Darwin discover?
As he observed those wonders for himself, Darwin pocketed thousands of specimens. His assemblage of fossils and rocks, along with animal and plant samples, included those of 13 mammal species.
Which island did Charles Darwin discover?
the Galapagos Islands
On September 15, 1835 on the return route across the Pacific, the Beagle arrived in the Galapagos Islands. Darwin disembarked on San Cristóbal (September 17-22), Floreana (September 24-27), Isabela (September 29-October 2) and Santiago (October 8-17).
What did Darwin discover on the Beagle?
His observations led him to his famous theory of natural selection. According to Darwin’s theory, variations within species occur randomly and the survival or extinction of an organism is determined by its ability to adapt to its environment.
What organism and trait did Darwin observe in the Galapagos Island?
Visible Evidence of Ongoing Evolution: Darwin’s Finches
From 1831 to 1836, Darwin traveled around the world, observing animals on different continents and islands. On the Galapagos Islands, Darwin observed several species of finches with unique beak shapes.
What unusual feature did Darwin find in the tortoises on the Galapagos Islands?
For example, Darwin observed a population of giant tortoises in the Galápagos Archipelago to have longer necks than those that lived on other islands with dry lowlands. These tortoises were “selected” because they could reach more leaves and access more food than those with short necks.
How did the Galapagos tortoise get to the Galapagos Islands?
Scientists believe the first tortoises arrived to Galapagos 2–3 million years ago by drifting 600 miles from the South American coast on vegetation rafts or on their own. They were already large animals before arriving in Galapagos.
What was Charles Darwin’s Favourite animal?
In high spirits: meet Charles Darwin’s favourite octopus. Aboard HMS Beagle in 1832, near the Cape Verde island of Santiago (then called St Jago), the young naturalist Charles Darwin met his match in the form of a common octopus.
Why did Charles Darwin eat exotic animals?
Darwin developed his exotic appetite at a young age. During his student days at Christ’s College, Cambridge, he presided over the University’s Glutton Club. The main objective of the club was to seek out “strange flesh” and consume the “birds and beasts which were before unknown to human palate.”
What animals did Charles Darwin eat?
During the voyage of The Beagle, he ate puma (“remarkably like veal in taste”), iguanas, giant tortoises, armadillos. He even accidentally ate part of a bird called a lesser rhea, after spending months trying to catch it so that he could describe the species.
How many species of animals are on the Galapagos Islands?
Nearly 9,000 species are found on the islands and their surrounding waters, many of them endemic.

What animals were the first visitors to the Galapagos Islands?
For the most part, the first settlers of the Galapagos Islands were British sailors who arrived motivated by the whales, sperm whales, sea lions, and mainly by the giant tortoises that inhabited the islands. However, the discovery of sperm whale blubber and its primary use as lamp fuel also attracted whalers.
