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.
Charles Darwin
Darwin observed different species of finches with specialized beaks for different diets on the Galapagos Islands. He also noticed variations in tortoise shells and iguana sizes across different islands. These observations contributed to his development of the theory of natural selection and evolution.
Galapagos Islands are the islands where Charles Darwin observed variation among organisms.
Charles Darwin observed variations in the characteristics of animals and plants on the different islands of the Galapagos during his voyage on the HMS Beagle in 1835. These observations played a key role in the development of his theory of natural selection.
~Darwin observed that the characteristics of many animals and plants varied noticeably among the different Galapagos Islands. They also had different adaptations, such as beak size and shape, and tortoises' shell shape, with helped them survive in their environment.

The Galapagos Islands
No, evolution has created different species of finches on the Galapagos Islands. There are 15 different species that are found on the Galapagos islands.

Darwin discovered unique species of finches and tortoises in the Galapagos Islands that helped shape his theory of evolution by natural selection. He observed how these species had adapted to different environments on different islands, leading him to propose that species can evolve over time to better suit their surroundings.
No , False
On the Galapagos Islands, Charles Darwin observed unique species of birds, tortoises, finches, and marine iguanas. These observations contributed to the development of his theory of evolution by natural selection.
Charles Darwin reached the Galapagos islands in 1835. He observed many finches, tortoises and many other animals. He observed that the animals in the Galapagos were different than the animals in other places like south America. This may be because the climate is different in the Galapagos than in other places so the animals may have involved to suit the temperatures in the Galapagos.
