The second thing Charles Darwin studied was Volcanic islands in 1844. I did a project on him and it has been checked so you can rely on this information.
Charles Darwin had no knowledge of genetics, which had not yet been discovered.
The most challenging thing that happened to Darwin in his life was that his daughter died when she was 10 years old, and that took the heart out of him.
The key thing that Darwin realised soon after arriving at the Galapagos was that the islands had been formed relatively recently. Because of this, a relatively small number of species had arrived at the islands and variations on these species had arisen on the different islands. This made Darwin ask how the variations had occurred; leading, eventually, to the theory of Natural Selection.
He didn't. Charles Darwin did not like the rough and tumble of public debate about his idea, though scientific debate was another thing altogether. The debate had spilled over into the public arena and needed on the spot debaters, which Charles Darwin was not. So, Darwin's friends that he first convinced of the rightness of his theory went to bat for him. Thomas Huxley, Darwin's bulldog, was foremost among them, but there were also others. Hooker, Lyell, and Wallace were the other main defenders of the theory in Darwin's stead.
Charles Darwin was amazed by the variations in the beaks of Galápagos finches, which seemed to be adapted to their specific diets on each island. This observation ultimately led Darwin to propose his theory of natural selection and evolution.
Darwin first went to the university of Edinburgh to study medicine but he didn't like the sight of blood. He then moved to Christ's College, Cambridge to study to become a preist. He didn't finish the course.
No. There was a rumor circulating that Darwin recanted evolution on his death bed, but that rumor has no foundation or plausible evidence. And even if Darwin ever had said such a thing, it would be meaningless. Galileo recanted is heliocentric theory, under pressure from a religious group. That in no way alters the fact the earth orbits the sun, and not the other way around.

In the finches, Charles Darwin observed the different beak shapes according to where they lived in the Galapagos. He later linked their beak shapes to the food they ate. Their beaks were shaped to make it more convenient to get their food. In tortoises, he observed the shapes of their shells. The shell shapes got either progressively curvier or progressively less curvy as you travel up or down the island. And I'm not 100% sure about the theory thing, but I think it's the Theory of Evolution
Yes, and no. Yes, back then it was the most accurate possible assessment of the data available at the time. But evolutionary theory today is much different from the model that Darwin first proposed. For one thing, evolutionary theory now includes modern knowledge of genetics. For another, we no longer believe, like Darwin did, that evolution is uniformly gradual.
the animal Darwin examined were finches on the Galapagos islands (at least finches were the main thing he studied)
