CHARLES Darwin was a great Victorian geologist, naturalist and one of the most important scientists in history. On his birthday, 12 February, we celebrate and honour the man behind the theory of evolution.
He looked closely at the natural world, studying organisms and their environment, and developed ideas about how the Earth and its inhabitants had evolved. Darwin’s scientific theories were very different from those of other people at the time, and it took great courage for him to publish his ideas. Today, Darwin’s most significant idea, the Theory of Evolution, shapes the way that many of us think about our past and where we came from. him later develop his theory of evolution. outlined his controversial idea that members of the same species could change over time in order to adapt more successfully to their environment. Darwin used the beak types of finches as an example. Over many years, finches that had moved to new environments had developed different types of beak to enable them to make use of new food sources. Darwin further argued that existence is a competition and individuals with an advantage over those around them (such as a finch with a beak better adapted to its surroundings) would survive longer and be able to reproduce, passing on that advantage to the next generation. Eventually, these small advantages or changes could add together to create an entirely new species. Darwin later discussed this idea in relation to people, arguing that over thousands of years, humans and apes had descended from the same ancestor in this way.
