What did Charles Darwin observe on the Galapagos Islands?
different finch populations that appeared closely related Charles Darwin, while on the Galapagos Islands, studied finches and their beak structure as their ability to eat fruits, nuts and bugs.
Why did Darwin say the finches on the galapagos lslands were new species of finches?
Darwin did not say this. Darwin collected finches from the Galapagos islands, believing them to be other words. It was the famous ornithologist, John Gould, who confirmed that 12 samples were all finches, but with enough minor differences for them to be considered new species. While it was Gould who called them new species, it confirmed to Darwin some of the ideas he'd had about the stability of species, how one colony of organisms can split up and adapt to a new environment.
What evidence of evolution did darwin present to the world?
Charles Darwin visited Galapagos Island during his famous voyage around the world. He did research on finches and the Galapagos Giant Tortoises during his stay there. He found that these animals have developed themselves according to their habitat. The tortoises living in the surroundings where food was available at low height had round carapace while those who lived in the surroundings where food available at high height had saddle back carapace. Similar with the finches, It was sound that there was difference in the same species of animals at all the seven islands at Galapagos. This observations made by Charles Darwin lead him to came up with the Theory of evolution.
What accounts for the large number of different species of finches that Darwin observed on the Galapagos Islands?
The varying local conditions on each of the islands. Each group of finches was bred, through natural selection, to have the characteristics that would optimize finch survival on that island. For example, an island might have a unique food source, say a type of nut, so the finches that had more robust beaks and could break these nuts more easily got to eat more food, survived more often, and could provide for their young better, so over time they became more numerous on the island while the less fit ones declined in number until only finches with robust beaks were left. This is the basics of the idea.
True or false while in galapagos islands did darwin notice a slight difference in the animals from one island to the next?
It is true that while in the Galapagos Islands, Darwin noticed slight differences in the animals from one island to the next. Charles Darwin was an English naturalist.
What did Darwin study while sailing?
he study finches on his way back

What was Charles Darwin's Education?
While he was studying finches (small birds) in different islands, he noticed that although they were from the same species, they were different. He realised that over time species change and adapt to their environment. This is how he came up with the Theory of Evolution.
What led Darwin to theory of evolution?
Charles Darwin observed that the beaks of several finches on the Galapagos Islands were adapted to specific purposes, and that, while they were all finches, they had adapted different characteristics to perform different functions (different feeding for differently shaped beaks). This led him to conclude that organisms can and do change to perform necessary tasks more conveniently. He expounded upon this conclusion, eventually publishing his renowned On the Origin of Species.
How were Darwin's finches different?
The Darwin finches were the finches of which Darwin studied and analysed so that he could notice the natural selection process. He stuided finches on different islands, all with different beaks. This showed that by natural selection these finches had adapted and evolved into their own environments.
During Darwin voyages to the Galoagos Islands he saw 13 species of finches How did the finches differ and what was Darwin explanation for the differences?
When Charles Darwin saw the different species of finches on the Galapagos Islands, he recored many hand drawn pictures of them. They differed in beak style. Some had beaks better suited for pecking bugs out of trees, while others were better at picking them out of the ground. His explanation for the differences was that they evolved over time to adapt better to their surounding and to have a greater chance of surviving. This was his theory of Natural Selection.

What did Darwin infer from his observations of organisms in south America and the Galapagos's islands?
All the species of finches on the Galapagos Islands appear morphologically very similar, varying mostly in terms of beak size and behavior; they all look very much like a species of finch from the mainland of South America. This suggests that all the finches on the Galapagos are descended from one original colonist species that went through an adaptive radiation. Because of the small, isolated environment of the Galapagos, the finches have become the topic of extensive study into natural selection. The studies that have been conducted on the finches show strong selection for larger beaks during droughts. These data show that climatic changes can have profound effects on the morphology of a species and potentially lead to the formation of new species. When Darwin visited the Galapagos, he observed and collected some of the finch species, believing that they represented a very diverse set of birds that were not closely related. Their significance was not recognized until later, when ornithologist John Gould pointed out that the birds were all closely related finches (Desmond and Moore 1991). But because Darwin originally collected some of the specimens and because the finches showed so much evidence for evolution and natural selection, they have been dubbed "Darwin's finches." This has led many people to conclude (mistakenly) that Darwin's theory of evolution was specifically inspired by the finches The zoologist Thomas Bell showed that the Galápagos tortoises were native to the islands. By mid-March, Darwin was convinced that creatures arriving in the islands had become altered in some way to form new species on the different islands, and investigated transmutation while noting his speculations in his "Red Notebook" which he had begun on the Beagle. In mid-July, he began his secret "B" notebook on transmutation

What includes all of the knowledge gained while exploring the Natural World?
One method of obtaining knowledge about nature is to observe and record. This was the method used by scientists like Jane Goodall and Charles Darwin.
