Throughout time, great minds have produced ideas that have changed the world we live in. Similarly, in the Victorian times, Charles Darwin fathomed ideas that altered the way we look at ourselves and fellow creatures. By chance, Darwin met and learned of certain individuals who opened doors that laid the foundation for his theories which shook the world.
Darwin\'s initial direction in life was not the same as his final. He grew up in a wealthy sophisticated English family and at the age of sixteen, Darwin went to the University of Edinburgh to study medicine.(Darwin) Two years later, he decided to leave medical school and attended the University of Cambridge to become a clergyman of the Church of England.(Darwin) While at Cambridge, Darwin met Adam Sedgewick, a geologist, and John Stevens Henslow, a naturalist. Henslow built Darwin\'s self confidence and taught him how to be an exact and painstaking observer of nature and collector of specimens.(Spruce) After graduating from Cambridge University, Darwin went aboard the English survey ship HMS Beagle, largely because of Henslow\'s recommendation, as an unpaid naturalist on a scientific expedition around the world.(Darwin)
Before the time of Darwin, most geologists believed in the catastrophist theory that the earth had experienced a succession of creations of animal and plant life, and that each creation had been destroyed by a sudden catastrophe.(Somervell 127) According to this theory, the most recent catastrophe, Noah\'s flood, wiped away all life except those forms taken into the ark. The rest of the organisms were only visible in the form of fossils. "In the view of the catastrophists, species were individually created and did not change over time"(Darwin). This catastophist theory was widely accepted before such scientists as Darwin published their theories.
Darwin\'s job on the Beagle gave him the opportunity to observe the "different geological formations and climates, as well as a large variety of fossils and living organisms"(Spruce). He was impressed with the effect that natural forces had on the shaping of the earth\'s surface.(Darwin) Darwin found himself fitting many of his observations into the theory that the earth is undergoing constant change.(Spruce) He realized that some of his own observations of fossils and living plants and animals cast doubt on the accepted theory that species were specifically created.(Spruce) He noted, for example, that fossils of organisms said to be extinct closely resembled living species in the same area. In the Galapagos Islands, Darwin also observed that each island had its own kind of tortoise, mockingbird, and finch; the various kinds were closely related but were different in the aspects of structure and eating habits from island to island.(Darwin) Both observations, raised the !
question, for Darwin, of possible links between distinct but similar species. Darwin\'s opportunity of sailing around the world laid the basis for his theories.
After returning to England, Darwin began recording his ideas about the changeability of species in his notebooks on the "Transmutation of Species". Darwin\'s explanation for how organisms evolved was brought into sharp focus after he read "An essay on the Principle of Population" by Robert Malthus, who explained how human populations remain in balance.(Darwin) Malthus argued that the availability of "food for basic human survival could not match the rate of growth in the population. The population was altered by natural limitations such as disease, famine, and war"(Darwin). Darwin immediately applied Malthus\'s argument to animals and plants. By 1838, Darwin had arrived at a sketch of a theory of evolution through natural selection.(Spruce) For the next two decades, Darwin worked on his theory and other natural projects. Darwin\'s complete theory was published in 1859, in On the Origin of Species. The book was often referred to as "the book that shook the world".(Somerv!
ell 128) Darwin\'s book sold out on the first day of publication and it went through six editions.
Darwin created many theories which were published in his book. Darwin\'s theory of evolution by natural selection is that because of the food supply problem described by Malthus, the young born to any species must compete for survival.(Spruce) Those young that survive to produce the next generation tend to embody favorable natural variations.(Spruce) This process was called the process of natural selection. These variations are passed on from generation to generation. Therefore, each generation will improve adaptively over the

The Sepoy Mutiny of 1857The Sepoy Mutiny of 1857 As with any conflict or controversy there are always two sides to the debate, and the events in India during 1857 are certainly no exception. Given the situation in India during the nineteenth century it is hardly surprising that such a polarisation of opinion exists regarding the context of the rebellious events during that year. The British being in control of the subcontinent and their sense of superiority over their Indian subjects, would naturally seek to downplay a
Charles DarwinCharlesDarwin In 1859 when CharlesDarwin published his book The Origin of Species, it caused much controversy between the scientific and religious worlds. It caused many people to question their belief in the teaching of the Bible. The strongly held belief that the Bible was the literal truth clashed with the Darwin theory. Some people rejected and scorned Darwin while others tried to reevaluate their beliefs. Darwin theorized that species evolved from other species. The belief that God dire

The Theory of EvolutionThe Theory of Evolution The theory of evolution, as set forth by CharlesDarwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a warm warm little pond and that it took billions of years for the present diversity of living things to evolve. At the time, it was thoug
