The finches that inhabit the Galápagos Islands rely on a variety of seed types as their primary food source. Although these birds face different environmental conditions and dietary needs, their beaks exhibit a generally similar structure across the different species.

I calculated the distance from South America to the Galapagos on my journey here and it is approximately 605 miles, which is quite far. I assumed that since all the finches did not make it to this island they had to have different mutations that they did not share due to the distance. They adapted to their environments. So here began my study of all the different kinds of finches on different parts of the Galapagos compared back to the ones in South America.

I found it interesting as to how these birds flew all the way to the Galapagos. I decided to do some research to figure out why they came here and how they knew there was an island here. Then I discovered that they in fact did not migrate here on purpose. They were pushed over here by wind from South America.

I, Charles Darwin have discovered evolution and its relation to natural selection. Thank you for coming along with me on my journey to discover the functions of the species modifications over time.

In conclusion my discovery was that the Galapagos Finches showed evolution through adaptations to their environment when migrating from South America to the Galapagos Islands.
