This theory was accepted as a fact by the scientific community. However his notion of evolution through natural selection was not considered as the primary explanation of the evolutionary process until the 1930s. Today Natural Selection is the basis of the modern evolutionary scientific thought.
To achieve and carry out its work, Darwin obtained important elements during a trip to the Galapagos Islands. This trip to the Islands lasted two weeks and was enough to appreciate what Natural selection means. However, this naturalist not sensed then that it would take nearly 25 years after his visit to the Galapagos Islands, to publish his book "Origin of Species".
This trip took place in 1831, when Darwin joined the crew of the ship of the Royal Navy HMS Beagle, as a naturalist. The ship had the objective of mapping around the world during 5 years." This trip was essential in Charles Darwin thought”.
In the Galapagos Islands, in the Pacific Ocean, just in front of South America, he was very fascinated by species of animals he saw and, above all, the subtle differences between birds of the islands of the archipelago. Based on these observations, Darwin was aware that these differences could be connected with the fact that each species live in a different environment, with different feeding. At that time Darwin began to outline his ideas of evolution.
Darwin affirmed that entire population can be defined as groups of individuals slightly different one from another. The variations that exist between individuals make each one have different capacities to adapt to the natural environment, successfully reproduce and pass their traits to their descendants.
When the generation changes, the traits of individuals who were better adapted to natural conditions become more common and the population evolves. Darwin called this process "descent with modification". In the same way, nature selects the best adapted species to survive and reproduce. This process is known as "natural selection".
More than 20 years after from the moment he began to develop his ideas of evolution, Darwin published his theory on the Origin of Species (1859). Its publication caused great controversy and religious thinkers were opposed to the book because the creationist theory destroyed and moved humans from the Center of the creation. This book convinced the scientists and the public that living things change over time.
Just to remember, we have to consider that the Galapagos Islands are famous for its numerous endemic species, which motivated Charles Darwin studies and led him to establish his theory of evolution by natural selection; this is why the archipelago has the nickname of "Enchanted Islands".
In Galapagos you have an appointment that cannot be put off: visit the Charles Darwin station. This is an international non-profit organization dedicated to providing scientific research, support and technical information in order to ensure the proper conservation of the Galapagos Islands.
In the station work more than hundred scientists, educators, volunteers, research students and support staff from all parts of the world. 90% of the employees are Ecuadorian and the Foundation is committed long ago in the training of residents of the Galapagos so that they become scientists and conservationists of the Islands and Ecuador.
Charles Darwin visited the Galapagos Islands in 1835, and during his research here he conceived the theory of evolution.
Charles Darwin is a very important historical figure within the modern scientific.
The main Foundation responsible for the conservation and research in the Galapagos Islands is named after him: Charles Darwin Foundation.
