Charles R. Darwin


Charles Robert Darwin was the fifth child of Robert Waring Darwin


and Susannah Wedgewood. He was born on February 12, 1809 in Shrewsbury,


England where his father practiced medicine. He attended Shrewsbury


Grammar School which was a well-kn own secondary school which concentrated


on teaching classic languages. Even as a boy Darwin loved science and his


enthusiasm for chemical studies earned him the name “Gas” from his


friends.


The headmaster at Shrewsbury, Dr. Samuel Butler noted, “Here’s a boy,


plays


around with his gases and the rest of his rubbish and works at nothing


useful.” He was also an avid collector. Anything he could get his hands


on- shells, eggs, minerals and coins interested him.


Darwin was expected to follow his father and become a doctor and in


1825, at the age of sixteen, his father removed him from Shrewsbury and


entered him in the University of Edenburgh to study medicine. He found all


of his classes except chem istry dull. After two years at Edenburg, he


quit school and went to live with his Uncle Josiah Wedgewood. After he


abandoned medicine, his father urged him to attend Cambridge University to


study to be a clergyman. At Cambridge he met John Steven Henslow who


helped him regain his interest in nature. It was Henslow who was


influential in getting Darwin the position of naturalist on the boat The


Beagle. In April of 1831, he graduated from the University.


In the fall following his graduation, the government decided to


send the H.M.S. Beagle, under the command of Captain Fitzroy, to complete


an unfinished survey of Patagonia and Tierra Del Fuego to help map out the


shores of Chile and Peru. Th e voyage was to last two years. Darwin


volunteered his services without salary and offered to pay his own


expenses


on the condition that he was allowed to keep all the plants and animals he


collected. On Henslow’s recommendation, Darwin was chosen to serve as


naturalist for the exploration. The Beagle set sail from Devonport on


December 27, 1831 and returned on October 2, 1836. Throughout the journey,


Darwin shipped back to England crate loads of tropical plants, insects,


flowers, spiders, s hells and fossil animals. He was very popular with the


crew and was given the name “Fly Catcher.”


During the five year journey, he was exposed to different species


of birds, insects and reptiles. He noted that in the different


environments that he visited changes occurred in the same species that


helped them to adapt to their surrounding s. It was as a result of these


observations and observations of other naturalists and geologists that


Darwin began to formulate his theory of evolution known as “Natural


Selection.” Darwin had left England as a youthful collector and returned


as a dedicated naturalist. Before the journey, he believed like Henslow,


that the history of the earth was short and whatever changes occurred were


the result of vast catastrophes. By his return, he was convinced that the


earth was extremely old and its evolution was the result of many small


changes.


Natural Selection, proposed by Darwin, is the most widely accepted


theory on evolution today. The theory is based upon five basic principles.


The first states that organisms increase at a higher rate than their food


supply. However, while there is overproduction of organisms, there is


never


overpopulation because many young never reach adulthood. The second


>principle notes that because the resources of nature are limited, all life


engages in a struggle for survival in which only thos e with superior


characteristics survive. The third principle states that no two


individuals are identical. No matter how slight the difference may be,


all show some variation from one another. The fourth principle notes that


some individuals poss ess variations that are most helpful in adapting to


an environment, increasing their chances for survival. This in turn


enables them to produce more offspring. Darwin’s fifth principle concludes


that these offspring will inherit the favored charact eristics of their


parents and pass them on to their children. Each generation maintains and


improves the characteristics which help them diverge further from the


original type. Ultimately the new forms will be so different in structure


and behavior from the original, that they will not be able to breed with


them and are therefore considered a new species. In summary evolution is


based on the survival of the fittest. The individual who’s best suited to


its environment will have a higher survi val rate. Those not favorably


equipped will die preventing overpopulation of the earth. In November,


1859, Darwin published The Origin of Species in which he proposed his


ideas of evolution. The first edition was sold out on the day of


publicatio n and by 1860 over five thousand copies had been sold.


Instantaneously conflict arose and “Darwinism” was put on trial. Darwin


was attacked as a blasphemous radical by the church. Scientific journals


contained articles critical of his theory. Eve n some of Darwin’s closest


friends turned on him. Darwin, himself, stayed clear of the debate and


arguments knowing he had done his work well and it would be its own best


defense. Samuel Wilberforce, the Bishop of Oxford, spoke for the church


and c harged that Darwin and his followers were atheists who denied that


God was the creator. T.H. Huxley, Britain’s leading zoologist, defended


Darwin in the debate with the bishop and by using careful reasoning


convinced many to at least consider Darwin ’s theory as plausible. The


idea of evolution became popular with scientist all over the world.


Darwin lived another twenty-two years after the book was published,


but the major accomplishments of his life had concluded. However, he


continued to work observing earthworms, plants and anything else that


seemed interesting. His work beca me the foundation of modern biology and


established two new sciences- animal behavior and ecology. When asked what


drove him on he answered,”From my early youth I have had the strongest


desire to understand or explain whatever I observed and group a ll facts


under some general laws…”


On April 19, 1882 Darwin died of a heart attack. The family wanted


Darwin to be buried in his home, the village of Downe. However, Parliament


requested that he be buried in Westminster Abbey, a cemetery for Britain’s


kings and queens and i ntellectual giants. This was an indication of how


far Darwin had come towards universal acceptance and respectability.


Darwin’s coffin lies next to Issac Newton which is only fitting because


Darwin has been called “The Newton of Biology.” Darwin w as modest of his


monumental achievements to the very end and said of himself shortly before


his death,”With such moderate abilities as I possess, it is truly


surprising that I should have influenced to a considerable extent the


belief of scientific men on some important points.”
