Darwin's Theory on Natural Selection
Though his writing can be difficult to understand and at times boring, the structure is organized. His smooth and fluent style, helps the reader gracefully follow along. Though his findings inspired many scientists to scientifically analyze his claims, Darwin's studies were not with in the realm of science. Rather, his findings are logical which he found by studying various species among the natural world over a long period of time. The use of constant examples, scientific lingo and inductive reasoning all factor into Darwin's effectiveness in persuading the reader to accept his claims.

In his argument, he states, "...that a change in the conditions of life, by specially acting on the reproductive system, causes or increases variability". Those varieties who do not eventually adapt to sudden changes, decrease the likelihood of their survival. Any modification in structure, however, only benefits the species' likelihood of survival; such as green leaf eating insects, or mottled grey bark-feeders. Both of these critters camouflage to their advantage to sneak past their mighty predators. though these changes are beneficial, they develop only over a long and slow period of time. None of these changes are strikingly noticeable, only until further generations come to exist can we distinguish any difference from precious ancestors.

To further support his claims, Darwin uses the comparison between Man verse Nature.He states that unlike Man, Mother Nature takes her own course. caring nothing for appearance, unlike Man, Mother Nature only acts on what is "useful" or necessary for a species to survive. Declaring that "Man selects only for his own good; Nature only for that of the being which she tends" allows us to reasonably believe that Mother Nature is far more suited in adapting to the natural conditions of life. He argues that because man is so well capable to manipulate factors in his life, the productions of nature are...
