The life and contributions of charles robert darwin to modern biology

Darwin, Charles English naturalist — Charles Darwin was the founder of modern evolutionary thought, and the developer, along with Alfred Russel Wallace, of the theory that natural selection is a principle driving force in evolution. And by these means, humanity has attained, for better or worse, an unprecedented dominance over the entire globe.

His father, considering the year-old a wastrel interested only in game shooting, sent him to study medicine at Edinburgh University in Hooker increasingly doubted the traditional view that species were fixed, but their young friend Thomas Henry Huxley was still firmly against the transmutation of species.

Three Fuegians on board had been seized during the first Beagle voyage , then during a year in England were educated as missionaries. Lyell's uniformitarianism view opposed the generally-accepted catastrophism view proposed by Georges Cuvier. Lyell was intrigued by Darwin's speculations without realising their extent. Darwin was witnessing the social penalties of holding deviant views. Darwin is generally recognized as the single greatest thinker in the history of biology, whose contributions provided the basis for understanding the immense diversity that characterizes the natural world. Second, Darwinism refutes typology. But no consensus exists as to the source of this revolutionary change. The finds brought great interest when they reached England. He developed the theory of uniformitarianism, which holds that the Earth is very old, and that geological changes are due to slow, continuous processes. The application of the theory of common descent to Man deprived man of his former unique position. These biological concepts, and the theories based on them, cannot be reduced to the laws and theories of the physical sciences. A highly methodical scholar, constantly collecting and observing, he spent many years comparing and analysing specimens before finally declaring that evolution occurs by a process of natural selection. Uniformatarianism held that major geologic features, such as mountains and canyons, were formed not by rapid and short-lived catastrophic events such as floods, but rather by the slow, steady action of forces such as erosion. An caricature following publication of The Descent of Man was typical of many showing Darwin with an ape body, identifying him in popular culture as the leading author of evolutionary theory. Charles Darwin: history's most famous biologist By Kerry Lotzof First published 9 February Charles Robert Darwin transformed the way we understand the natural world with ideas that, in his day, were nothing short of revolutionary.

Darwin's pigeons From his travels on HMS Beagle, Darwin suspected that the environment might naturally manipulate species, causing them to change over time - but he couldn't find a means to explore this effectively in the wild.

By mid-March ofbarely six months after his return to England, Darwin was speculating in his Red Notebook on the possibility that "one species does change into another" to explain the geographical distribution of living species such as the rheas, and extinct ones such as the strange extinct mammal Macraucheniawhich resembled a giant guanacoa llama relative.

It no longer requires God as creator or designer although one is certainly still free to believe in God even if one accepts evolution.

On his death inin recognition of his scientific achievements, Darwin was buried in Westminster Abbey, along with Isaac Newton, Michael Faraday, and other great English scientists.

Part of his success has been attributed to his conversational and approachable writing style. Natural selection had produced 13 different species of finch.

Despite the initial resistance by physicists and philosophers, the role of contingency and chance in natural processes is now almost universally acknowledged. Darwin himself rarely commented on any connections between his theories and human society.

This viewpoint is called typology, or essentialism. The sample included small, medium, and large beaks. Despite the attacks, Darwin's conviction in the scientific explanation that best fit the available evidence remained unshaken. He now renewed a fascination and expertise in marine invertebrates , dating back to his student days with Grant , by dissecting and classifying the barnacles he had collected on the voyage, enjoying observing beautiful structures and thinking about comparisons with allied structures. Kin selection and reciprocal helpfulness in particular will be greatly favored in a social group. I shall be delighted to hear how you think that this change may have taken place, as no presently conceived opinions satisfy me on the subject. Darwinism swept such considerations away.

The world they inhabited had been created by God, and as the natural theologians claimed, He had instituted wise laws that brought about the perfect adaptation of all organisms to one another and to their environment.
