Galapagos Islands information

Every island in the Galapagos is different one from the other and all this is due to how they were formed. If the 4,600 million years of Earth´s history will be simulated in 24 hours, the Galapagos Islands had been formed in the last two minutes of that day. The 19 islands and 219 islets were created by successive volcanic eruptions over a hot spot located on the seafloor of the Nazca Plate. The first of them emerged in the middle of the Pacific Ocean about 5 million years ago. The islands are settled on the Nazca Plate and move about 5 centimeters a year eastward. That is why the oldest islands of the archipelago are far about 200 kilometers east from the youngest islands that are still above the hot spot.

Darwin Finches - Landbirs | Galapagos Islands Animals and Wildlife

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.
