It is commonly thought today that the theory of evolution originated from Darwin in the nineteenth century. However, the idea that species mutate over meter has been around for a long time in ane cast or another. Therefore, by Darwins time the idea that species change from purr type into another was by no convey new, only when was rejected by virtually beca hire the prop singlents of evolution could not distinguish up with a satisfactory mechanics that would explain this change. The most influential evolutionary theories prior to Darwin were those of Lamarck and Geoffroy St. Hilaire, developed amidst 1794 and 1830. Lamarck suggested that species evolve through the use or disuse of giving up inicular organs. In the classic manakin a giraffe that stretches its know slightly to reach higher leaves allow for gain in neck length, and this small gain would be passed on to its event. Geoffroy, on the other hand suggested that the change was discontinuous, large in ma gnitude, and occurred at the production of offspring. However, these theories of evolution were based on a priori explanations that offered no exhibit mechanism. Darwins theory of evolution differs in that it is based on trey easily verified observations. First, individuals within a species transfigure from one another in morphology, physiology, and behavior. Second, variation is in most part heritable so that variant forms have offspring that resemble them. Third, varied variants leave different number of offspring. Darwin than proceeded to flesh out on the mechanism of evolution by suggesting that in the habitual struggle for life, nature selects those individuals who be best suited (fittest) for the struggle, and these individuals in turn reproduce more than those who are less fit, and then changing the composition of the population. In cast upition to natural selection, Darwin as well as suggested that species in like manner evolve through the complementary.. .
--References --> i am 10th grade stundent. this essay is in my book. it copied by raillery to newsworthiness . he only changed the last part and said Darwin has rightly earned his place in history as one of the giants of the scientific revolution. This is the only part which is not copied the essay is little broad. certain points shoild have been more resaerched and ellaborated on so add together across t he point more force estimabley. I am a teacher so i know.... I beleive that the suffice of this essay is good. oddly for a 10th grade paper, save even if it is copied from a book as jasdee states, it needs more elaboration. For example, what is Paleys idea or Lamaarcks idea, etc. Some of the info is also unnecessary. For example, Darwins grade schools teachers observe is irrelevant. A good paper for facts, entirely not for piece. If you want to get a full essay, order it on our website:
