Evolution is the change of inherited characteristics within a population over time through natural selection, which may result in the formation of a new species.
Charles DarwinAn English naturalist (1809-1882). In 1859 Darwin published On the Origin of Species, which outlined his theory of evolution. was an English naturalist who studied variation in plants, animals and fossils during a five-year voyage around the world in the 19th century. Darwin visited four continents on the ship HMS Beagle.
Darwin observed many organisms including finches, tortoises and mocking birds, during his five week visit to the Galap谩gos IslandsIslands in the Pacific Ocean, visited by Charles Darwin., near Ecuador in the Pacific Ocean. He continued to work and develop his ideas once he returned from his voyages.
Darwin's theory of evolution challenged the idea that God made all the animals and plants that live on Earth, which contradicted the commonly held Christian views of his era. He did not publish his scientific work and ideas until 28 years after his voyage.
Finally, as a result of Darwin's world expedition and observations, which were backed by many years of experimentation; his discussions with like-minded scientists and his developing knowledge of geology and fossils; he proposed the theory of evolution by natural selection.
Darwin proposed that:
individual organisms within a particular species show a wide range of variation for a characteristic
individuals with characteristics most suited to the environment are more likely to survive to breed successfully
the characteristics that have enabled these individuals to survive are then passed on to the next generation
