why did darwin go on the beagle

What did Darwin notice about the animals on these islands?

In this island Darwin noticed that most species were similar but different from other in the other islands, giving enough evidence to theorize that species change and this is related to their feeding and surroundings. He collected finches that helped him to understand this resolution.

What influenced Darwin’s theory of evolution?

During his voyage on the Beagle, Darwin made many observations that helped him develop his Theory of Evolution. … Darwin was influenced by other early thinkers, including Lamarck, Lyell, and Malthus. He was also influenced by his knowledge of artificial selection.

What did Darwin and Gould conclude about the finches found on the islands?

When did Darwin return from the voyage of the Beagle?

We now know that Darwin deserves most of the credit. In 1837, one year after he returned from the voyage on the Beagle, he made detailed notes on the idea of evolution by means of natural selection. At that time, Wallace was only 14 years old.

What did Darwin discover on the HMS Beagle?
