An introduction to aristotles and charles darwins teleological methods

In the Islamic Golden Age of the 8th to the 13th centuries, philosophers explored ideas about natural history. These ideas included transmutation from non-living to living: Conway Zirklewriting about the history of natural selection insaid that an excerpt from this work was the only relevant passage he had found from an Arabian scholar. He provided a quotation describing the struggle for existence, citing a Spanish translation of this work:

It was rejected by most, because the proponents of evolution could not come up with a satisfactory mechanism that would explain this change. The most influential evolutionary theories prior to Darwin were those of Lamarck and Geoffroy St. Hilaire, developed between and Lamarck suggested that species evolve through the use or disuse of particular organs.

In the classic example a giraffe that stretches its neck slightly to reach higher leaves will gain in neck length, and this small gain would be passed on to its offspring. Geoffroy, on the other hand suggested that the change was discontinuous, large in magnitude, and occurred at the production of offspring.

However, these theories of evolution were based on a priori explanations that offered no demonstrated mechanism. Individuals within a species vary from one another in morphology, physiology, and behavior.

Twentieth-century resurgence

Variation is in some part heritable so that variant forms have offsprings that resemble them. Different variants leave different number of offspring. Darwin then proceeded to elaborate on the mechanism of evolution by suggesting that in the universal struggle for life, nature "selects" those individuals who are best suited fittest for the struggle, and these individuals in turn reproduce more than those who are less fit, thus changing the composition of the population.

In addition to natural selection, Darwin also suggested that species also evolve through the complementary process of sexual selection. According to Darwin, in sexual selection, one gender of a species develops a preference for individuals of the other gender who possess certain features.

The individuals who possess these features will then have a reproductive advantage over others, resulting in a greater number of offsprings, and thus, again, a change in the composition of the population.

Therefore, it was Darwin who made the theory of evolution feasible by providing the mechanisms of natural and sexual selection.

Charles Darwin was born in England in to a wealthy and respectable family. His grandfather, Erasamus Darwin, was a noted botanical expert in his day who published two important books, Zoonomia, and The Botanic Garden. In these books, Erasamus speculated about various evolutionary ideas that were dismissed as too radical i.

Nevertheless, Erasamus may have unconsciously influenced Darwin in preparing the way for evolution by natural selection.

Inat the age of 9, Darwin entered the Shrewsbury school, which was run by Dr. Darwin later recalled that "nothing could have been worse for the development of my mind than Dr. The school as a means of education to me was simply a blank".

He was removed from the school inand was sent to Edinburgh to study medicine.

Foundational Issues

But before he left Edinburgh, he was introduced for the first time to the theories of Lamarck. To Darwin a good education meant instruction in the methods and logic of thought. For the rest, however, he judged Cambridge to be just as much a waste of time as Edinburgh and Shrewsbury.

Darwin later confessed that these books inspired in him "a burning zeal to add even the most humble contribution to the noble structure of Natural Science".In Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species ().

Unlike Lamarck, Darwin proposed common descent and a branching tree of life, meaning that two very different species could share a common ancestor.

That background is the Enlightenments abandonment of Aristotelianism, and in particular the Aristotelian concept of teleology, Renaissance science rejected Aristotles teleological physics as an incorrect and unnecessary account, which led Renaissance philosophy to make a .

Charles Darwin And The Theory of Evolution It is commonly thought today that the theory of evolution originated with Darwin in the nineteenth century, however, the idea that species mutate over time has been around for a long time in one form or another.
