More about Darwin Finches
Darwin finches are a group of about 14 birds that gained notoriety when Charles Darwin studied them back in his voyage with the HMS Beagle in 1835. Darwin arrived in the Galapagos and was fascinated by collecting species he found in his trip — the species were taken back to the UK for further studies.
Back home, Darwin studied the birds with ornithologist John Gould and found fascinating similarities between these birds and a common South American ancestor finch. They noticed that finches had slight differences in the beaks and were also as a whole different from the original continental ancestor. Each finch had adapted to their own island environment and food source availability with variations in their claws, size, and beaks — deriving from this they were acknowledged as endemic to the Galapagos Islands.
Some finches have adapted to eat insects, others to eat nuts, others are completely vegetarian. Charles Darwin, years later, gathered all his findings in his famous book On the Origin of Species and concluded that species have the ability to change throughout time making favorable adaptations to their environment and becoming new species. This is what we commonly know as the theory of evolution by means of natural selection.
