What observations did Darwin make during his time on the Galapagos Islands? He also discovered everything else the Galapagos is known for, including the giant tortoise and the marine iguana. Darwin hypothesized that finches naturally have a diversity of beak size, with some birds having larger ones than others in a population. If the island these birds are on has only large nuts, then the birds with smaller beaks will die off, not being able to crack those nuts and, thus, starving.

Charles Darwin Charles Robert Darwin, FRS FRGS FLS FZS was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. He established that all species of life have descended over time from common ancestors and, in a joint publication with Alfred Russel Wallace, introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artific

Charles Darwin Charles Robert Darwin, FRS (12 February 1809 – 19 April 1882) was an English naturalist and geologist, best known for his contributions to evolutionary theory.[I] He established that all species of life have descended over time from common ancestors, and in a joint publication with Alfred Russel Wallace introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

- Three hundred years later, in 1835, these “worthless” islands—with their vast number of endemic species—contributed to Charles Darwin’s theory of evolution. Now a UNESCO World Heritage Site, the Galápagos Islands are considered a “living laboratory” of evolution, and draw scientists and visitors worldwide. Credit: © Top-Pics TBK / Alamy.

CH 14 Some of Darwin's most important discoveries were based on studies of birds and tortoises he observed in: the Galápagos Islands. The theory of natural selection states that:

- Darwin discovered that finches he collected in the Galápagos were similar, yet distinctly different from one another and also different from the similar species on the mainland. He concluded that the finches could have descended with modification from a common mainland ancestor.

What adaptations did Darwin notice in finches? He noticed that the finches all had different beaks which varied in sizes. He concluded that this could be due to them living on different islands where the food sources were … different so the would have had to adapt themselves to suit their living environment. 11 people found this useful.

Galapagos Islands Discovered, Deemed Worthless Unbeknownst to him, Berlanga had just discovered the Galápagos Islands. After an initial exploration, Berlanga considered the islands useless. In a letter to the King of Spain, he described them as uninhabited, barren, and useless, with only birds, seals, and reptiles populating the desolate landscape.

Darwin's finches Darwin's finches. Darwin's finches (also known as the Galápagos finches) are a group of about fourteen species of passerine birds. They are often classified as the subfamily Geospizinae or tribe Geospizini. They belong to the tanager family and are not closely related to the true finches.

Each currently holds the position of emeritus professor. They are known for their work with Darwin's finches on Daphne Major, one of the Galápagos Islands. Since 1973, the Grants have spent six months of every year capturing, tagging, and taking blood samples from finches on the island. They have worked to show that natural selection can be ...

- Darwin would later base some of his thought from the supposing that these finches were all descendents of the same lineage. Years later in 1859, Darwin finally consolidated all of his observations into his famous book On The Origin of Species, drastically and controversially altering the scientific view on the biological origins of life.

Charles Darwin Charles Robert Darwin (12 February 1809 – 19 April 1882) was an English naturalist. He was born in Shrewsbury, Shropshire. He is famous for his work on the theory of evolution. His book On the Origin of Species (1859) did two things. First, it provided a great deal of evidence that evolution has taken place. Second, it proposed a theory to explain how evolution works.
