Each of these kinds was created with a vast amount of information. There was enough variety in the information in the original creatures so their descendants could adapt to a wide variety of environments. All sexually reproducing organisms contain their genetic information in paired form.
Ellwood University of Missouri It often happens in the history of science that the influence of a great thinker and investigator in one field penetrates to many related fields.
It is not often, however, that the influence of such a man comes to dominate in other fields than his own. Yet this is undoubtedly what has happened in the case of Darwin ; and perhaps in no field outside of his own is the dominance of Darwin's influence to be seen more clearly to-day than in sociology.
John Fiske said, that Herbert Spencer was the most eminent thinker that England produced in the nineteenth century: When one reflects upon the immense influence which Darwin's work has had on practically all lines of human thought, and especially on the biological, psychological, and social sciences, one is forced to conclude that Fiske's estimate must be revised, and that Darwin must be given the seat of highest honor as the most fructifying thinker which the nineteenth century produced, not only in England, but in the whole world.
And the social significance of Darwin's teachings is even yet only beginning to be apprehended. Not that Darwin had any theory of his own regarding human society. Outside of a couple of chapters in his Descent of Man lie says little specifically regarding Charles darwin s work has influenced evolutionary psychology problems of human society ; and it must be admitted that what little he says is not peculiarly valuable or profound, but only suggestive.
In spite of the vast range of his mind and of his scientific labors, Darwin, then, was not especially interested in social problems and made no direct contribution to sociology. On the other hand, Spencer was primarily interested in social problems.
His first considerable work, Social Statics, was along sociological lines, while his whole synthetic philosophy was confessedly developed to support his social and political theories.
Nevertheless, as was said above, it has come about that Spencer's influence in sociology is waning, while the influence of Darwin, who was not a sociologist at all and not even greatly interested in social problems, is growing.
The reasons for the decrease of Spencer's influence in sociology and the increase of Darwin's are not far to seek. Spencer sought his principles of social interpretation in the physical sciences, as his work on First Principles clearly shows.
He aimed at explaining social phenomena in terms of the redistribution of matter and energy. While he found it impossible to carry out an interpretation of social life in these terms, his conception of evolution, and even of social evolution, remained mechanical to the last.
Spencer's social interpretations, then, being fundamentally in terms alien to the social life, were fore-doomed to failure. Again, Spencer's social and political theories were largely based upon the ideas and prejudices of the average middle-class Englishman of his time ; and his knowledge of biology and psychology did not greatly alter his social theories, but rather the latter powerfully influenced his biological and psychological views.
Under these circumstances it is not surprising that many of Spencer's social theories were of a temporary character. Darwin's methods, on the other hand, were totally different. We find in him no appeal to vague principles borrowed from the physical sciences ; but on the contrary he attempts to explain the life-process in terms of its own elements.
As is well known Darwin got the key to his natural selection theory of organic development from Malthus, a writer on social and economic problems. Malthus, in his sociologic study of the growth of population, demonstrated that the normal rate of reproduction in man is in some geometric ratio, and consequently, to use Malthus's own metaphor, nature invited more guests to her banquet than she laid covers.
Hence arose, according to Malthus, a struggle for existence in human society, in which the weaker succumbed to poverty, disease and death, while the stronger survived. Darwin seized upon this idea and generalized it, applying it to all organic nature and deducing therefrom his famous doctrine of the natural elimination of the inferior and the evolution of higher types through the 'natural selection' of the better adapted.
It may be suggested that Darwin's principle of natural selection found ready acceptance in sociology because it was a principle which had already been recognized and applied, though in a negative way, in social theory.
However, the deeper reason for the strong influence which Darwin's work has had upon sociology is probably the simple fact that his work was upon a part of sociology's foundations. Sociology, as a body of theory regarding the origin and development, structure and function of human society, could not develop until biology had developed.
Spencer worked largely at rearing a sociological superstructure for which the necessary biological and psychological foundations had not been laid, while Darwin worked at these foundations. However much Darwin's selection theory of organic evolution may have to be modified by the biologists of the future, there is no doubt that his work established biology upon a secure scientific basis.
The inevitable consequence has been that Darwin's work has reacted to enrich immeasurably all the sciences in any way connected with biology. The greatest effect of Darwin's work on sociology has been of course in connection with the theory which is particularly associated with his name: While it is one of the moot points in biology just now whether natural selection operating upon minute variations even through immense periods of time is capable of producing new species, there has never been any doubt since Darwin wrote that selection is a powerful modifying influence upon all forms of life through its 'fixing' certain variations.
In this sense Darwin demonstrated that selection is the chief creative force in the biological realm.Fulfillment by Amazon (FBA) is a service we offer sellers that lets them store their products in Amazon's fulfillment centers, and we directly pack, ship, and provide customer service for these products.

Charles Darwin's Legacy.
Charles Darwin's theories were controversial in his day because they centered on the idea that humans and animals shared a common evolution and ancestry. Natural selection is the differential survival and reproduction of individuals due to differences in regardbouddhiste.com is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection .
Late in Charles Darwin's life, Darwin told the Duke of Argyll that he frequently had overwhelming thoughts that the natural world was the result of design. See also: 15 questions for evolutionists.
