More than a century after his death, and four generations after the
publication of his chief work, "The Origin of Species", Charles Darwin may still
be considered the most controversial scientist in the world. His name is
synonymous with the debate that continues to swirl around the theory of
evolution, a theory that deeply shook the Western view of humanity and its place
in the world.

We tend to speak simply of the theory of evolution, leaving off the
explanatory phrase, "through natural selection." At most, perhaps, the general
public has heard of "survival of the fittest" a poor phrase as far as I'm
concerned, since fitness in everyday usage is associated with physical
conditioning and athletic ability. "Survival of the most suited to its
environment" would be a more accurate, and convincing expression for this
pedicular concept. But to most of us, "evolution" simply means that human beings
are descended from apes, a slight misunderstanding, since both humans and modern
apes are descendants of a mutual ancestor that is now extinct. It's not
evolution but the theory of natural selection and the evidence he collected to
prove to fellow scientists, peers, students, and most importantly the masses of
public and the church that were at the heart of Darwin's contribution to
biological science.

Charles Darwin did not invent the concept of evolution. A number of prominent
scientists and other thinkers during the eighteenth century and the first half
of the nineteenth century (among them Charles Darwin's grandfather, Erasmus
Darwin) had offered detailed theories of evolution (Clark, 1984, pg.24-25).
Therefor the idea of evolution went very far back in Western history.

At that time this concept was referred to as The Great Chain Of Life and was
conceived in the middle ages, based on a mixture of classical and Biblical ideas.
The ranking order ranged from the "lowest" forms of life to "higher" living
beings (lion), through the various classes of human beings from peasants to
nobles to Popes, and upwards through the hierarchy of angles to God.

This concept, in and of itself, has nothing to do with evolution, in fact it
seems to be anti-evolutionary, since every member is fixed in its own place.
This chain was created in a time when the world was considered to ...

... the principle of natural selection.

Natural selection, as Darwin saw it, simply can not be ignored. For just as a
largely barren earth is re-colonized by the survivors descendants, which must
adapt through either variation or mutation to fill the ecological niches left
empty by the prior extinctions. Just as an area devastated by a forest fire are
filled by an evolution of new forms, not by the existing ones from unburned
areas. We may not be able to see the entire history of evolution but from our
viewpoint we have hundreds of examples of natural selection taking place all
around us each and every second of each and every day. Fortunately, Charles
Darwin (and maybe I should credit Alfred Lord Wallace) had the insight and
boldness to conceive and develop a theory so controversial to his time and
culture.

Essay about Charles Darwin 's Theory Of Natural Selection

- Charles Darwin’s theory of natural selection is viewed by many as one of the most significant and influential ideas ever conceived. However it took Darwin 20 years to publish his book ‘the origin of species’, one of the primary reasons for this was that he feared the implications his theory would have on the world. Although the theory of evolution greatly enhanced and progressed science as well as deepen human understanding of nature, it came at a cost. The theory led to the development of Social Darwinism, which further created a variety of different sociological and political ideologies....   [tags: Natural selection, Charles Darwin, Evolution]

Essay on Charles Darwin 's Theory Of Natural Selection

- For centuries on end, the utmost importance and appraisal was given to God. God was the driving force of various civilizations; he was the reason behind every animal that was caught for food, every dollar that was made, and every large-scale phenomenon that occurred. Charles Darwin was one of the first men to challenge this global spirit in the 1860s through his theory of natural selection, one of many theories delineated in his book, On the Origin of Species. Natural selection was described by Darwin as: “any variation, however slight and from whatever cause proceeding if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic bei...   [tags: Natural selection, Charles Darwin]

Charles Darwin 's Theory Of Natural Selection Essay example

- Charles Darwin’s theory of natural selection has pointed out that all species have changed over time. It processed different identifications of natural selection which later in time brought newer developments of variations in species (Lewis, et al., 2013). As a result, individuals have been reproducing. Species continue to evolve over generations. The world in which individuals live in has progressed and has become more modern and therefore has strayed away from the boundaries of natural selection....   [tags: Charles Darwin, Natural selection, Evolution]

Essay on Charles Darwin 's Theory Of Evolution And Natural Selection

- The ideas that Charles Darwin presented in his Origin of Species went against basically all the accepted views at the time. He proposed theories such as evolution and natural selection. This strongly went against the ideas at the time, which were centered on the church, and God being responsible for all life and everything that was here on earth. Charles Darwin’s theories were first started on his expedition on the Beagle, where he observed many different species, and in particular the finches he saw on his journey....   [tags: Evolution, Charles Darwin, Natural selection]

- In 1859, Charles Darwin published On the Origin of Species: by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, a work which was set change the ideas on how people think about the natural world, how it works, ways in which it develops itself. Although making the briefest of commentaries about the human, parallels in thinking can be drawn on the behaviour of the natural world to the way of humans. It is important to understand nature first to be able to analyse the behaviour as humans is similar to that of the natural world, to understand the barriers that may effect change or to an extreme evolution....   [tags: Natural selection, Charles Darwin]

Charles Darwin 's Theory Of Natural Selection Essay

- There must be very few people from biology or evolutionary background who are not aware of the work of Charles Darwin. Charles Darwin proposed that evolution occurs through the process of natural selection. Natural selection is the process by which species adapt to their environment in order to survive. Species evolve from one to the next through random genetic mutation, if the said mutation is beneficial then it is preserved and is passed down to the next generation to help with the survival of that species....   [tags: Evolution, Natural selection, Gene]

Charles Darwin had first noticed the similarities of plants and animals when he took a five-year cruise on the H.M.S. Beagle, which was available to him through a friend from school. During the cruise Charles Darwin started becoming interested with the similarities between the plants and animals that were similar on different islands with similar climates, so he decided to study them more closely....   [tags: Natural Selection, Evolution Essays]

Charles Darwin's Theory of Evolution by Natural Selection Essay

-      Other than Mendellson and his studies with genetics, Darwin has by far contributed the most to our modern science. From his theories on variation of species to his explanation of natural selection Charles Darwin has shocked the world by proving the world older than previously thought and creatures not immutable. In this present day these theories are as common belief as a simple mathematical equation such as two plus two equals four; but in the year eighteen hundred and fifty nine Darwin not only risked his reputation with these far fetched findings but also the risk of being excommunicated from the church....   [tags: Natural Selection, Evolution Essays]

Charles Darwin’s Theory of Natural Selection Essay

- The famous naturalist Charles Darwin presented the theory of natural selection. He went on many journeys on sea and on land, following his interests of the nature and the change that happens in the nature, i.e., the change in species. Following his exposure to many different kinds of birds, insects and animals, he explained Natural Selection as "presentation of favorable variations and the rejecting of injurious variations."(131). Darwin used analogies and metaphors to demonstrate that different alterations occurred in the same specie, which helped them to adapt to their surroundings....   [tags: Natural Selection Essays]
