Why Is Evolution Important To Darwin?

Evolution is the theory that all different kinds of living things have developed and diversified from earlier forms during the history of earth.
Carl Linnaeus
Linnaeus is a import figure in the theory of evolution because he developed a way to name and organize species. He is often referred to as the 'father of taxonomy.' He developed a system for naming that scientists all around the world could use to classify different organisms because each country had different names for different organisms. His theory was officially published in 1735. His theory helped scientists identify organisms world wide.
George Buffon
George Buffon developed the modern definition of a species. The definition he came up with was a "group of organisms which can breed
and produce fertile offspring. He also believed in evolution and believed that organisms do change over time. He also suggested that humans and apes are related. His theory was published in 1949. He is important figure in evolution because he believed in evolution when most people during that time believed everything was created by god.
James Hutton
James Hutton believed in the theory of uniformitarianism.
He believed that the present is key to understanding the past. This was important because he believed that the Earth was perpetually being formed and that the natural forces now changing the shape of the earth's surface have been operating the same way in the past. His paper was presented before the Royal Society of Edinburgh in 1788. His theory helped Darwin greatly because Darwin began observing rocks and fossils.
Jean-Baptiste Lamarck
Jean-Baptiste Lamarck believed that microscopic organisms appear randomly from lifeless materials and then evolve into more complex forms through a constant striving of perfection. He believed that evolution occurred due to the inheritance of acquired characteristics. This provided scientists around the world with a theory of evolution, evolution was now a theory not just a myth. Although his theory was incorrect he was one of the first scientists to introduce evolution and Darwin based his research according to his observations. His theory was introduced in 1793.
Thomas
Malthus
Thomas Malthus believed in the theory of population. His theory was that one day there would be too many humans and not enough food for everyone. Any further increase would lead to population crash and diseases. He also believed that man is a lazy animal, who only cares about feeding his family. He is also credited with the theory of natural selection. He noticed that humans grow geometrically,while food sources grow arithmetically. He had a strong influence on Darwin because he realized that there were natural factors affecting population growth. He began publishing his books between 1798 and 1826.
Georges Cuvier
Georges Cuvier introduced the theory of catastrophism.
His theory stated that natural catastrophes such as floods killed off different plants and animals. He was one of the first scientists to introduce ancient species that once lived on Earth. He obtained this information by researching fossils. Many scientists during his time also believed in his theory. Darwin also used used Cuvier's research on fossils to develop his theory. He presented his theory in 1813.
Charles Lyell
Charles Lyell was a English lawyer and geologists who provided conclusive evidence for the theory of uniformitarism. He did not believe in Cuvier's catastrophic theory. He was one of the first scientist to actually provide proof for a theory, all the other scientist belived their theories but had no proof to back up their theory. Darwin used to read his books that he published in 1933.
Steven and Niles
Both Steven Jay-Gould and Niles Eldredge proposed the theory of punctuated equilibrium in 1972. Their theory predicts that change takes place in short periods of time tied to spectation time. Very little change was observed through fossils. Their theory suggests that Darwin`s theory is incorrect. They also believe that organisms share a common
ancestor.
Charles Darwin
Charles Darwin`s theory suggests that all life is related. He believed that all forms of life share a common ancestor. He belived complex creatures evolve from simplistic ancestors naturally over time. He also believed that random mutations occur within an organisms genetic code and if it is a beneficial mutation it helps aid survival. Overtime benefical mutations accumulate and and it results in a entirely different organism. He is mostly known for his theory of natural selection and is sometimes referred to as `the father of evolution. His book was published in 1859.
Alfred Russel Wallace
Alfred Russel Wallace is best known for independently proposing a theory of evolution due to natural selection. Darwin later published the same theory in 1859. He did his reaserch in Indonesia where he noticed that animals on one side of the Wallace Line looked like animals in Australia and on the other side they looked like Asian animals. Some theorist argue that Darwin stole Alfred`s ideas and published them before him.
