Organic evolution is better known as the "theory of evolution." There are three main theories of evolution, which are, the early theories proposed by Comte de Buffon, Baron Cuvier, and Lamarck, the synthetic theory, and the Darwin theory.In the 1700s, French naturalists, Comte de Buffon and Baron Cuvier concluded with the studies of fossils and comparative anatomy that life on earth had endured many changes through a long period of time. In the early 1800s, another French naturalist named Lamarck, proposed the first complete theory of evolution. He observed through his observations, depending on the extent to which the use of the structure, that an animal's body structure is able to change during its life span. He also noted that organs and muscles, which were used often, tended to become larger and stronger. On the contrary, the organs and muscles, which were used seldom, tended to become smaller and diminish.
With these observations, Lamarck concluded that these characteristics were hereditary. Proposed during two decades, the 1930s and 1940s, the synthetic theory involved a group of scientists. The group of scientists included two American biologists, Russian Theodosius and German Ernst Mayr, and the British geneticist and statistician Ronald A. Fisher. Together, they proposed the synthetic theory which combined Darwin's theory of natural selection with the ideals of genetics.
In 1808, French naturalist Chevalier de Lamarck contemplated a theory of evolution, although, his theory of evolution did not gain any recognition until 1858. In 1858, British naturalist Charles R. Darwin furnished his theory of evolution, also known as Darwin's theory. Along with Darwin's theory of evolution there early theories and t...

.... The Neanderthal Man was a survivor. It had a cranial capacity, which was similar in size to modern humans. The Neanderthal Man had basic advances in life style. The Neanderthal Man made basic clothes and constructed tools of advanced design.
The Cro-Magnon Man is regarded has the first fine artist on earth. Proof of this fine artistry is that of rich records of accomplishments in cave paintings, which Cro-Magnon made. He made these records From stone engravings and carved figures. Cro-Magnon amazingly spread to all habitable parts of the world. Modern Man, us, has learned from the teaching and evolvement of the Cro-Magnon. We have learned to grow our own food and domesticate our animals.
In addition we possessed the control over the environment and created cites and established civilizations. We act like animals, we eat like animals, and we are animals. The many theories of evolution such as Darwin's theory of evolution prove to us that we choose to believe that we are not animals when we really are. With the amazing changes and evolvement our species has undergone and as the twenty first century approaches us, who knows what forms of evolutionary change will come of us.

- Health Benefits of Going Organic – Just the Facts Step into any grocery store and you are sure to be bombarded with signs promoting the health benefits of going organic. “Eat healthy by going organic” is a common calling-card for all sorts of foods endorsing the advantages of switching to diet filled with organic foods. It seems to make sense to switch to organic foods, but unfortunately, research findings concerning the health benefits of an organic diet isn’t discussed and most consumers would probably be surprised at the factual findings....

- Controversy of the origin of life has increased. People feel evidence is necessary to determine a faith and many fear going against the word of God or nature of science. These people have established their own “religion” or belief called the intelligent design theory. Through a combination of scientific evidence and Biblical moralities, the intelligent design theory was established to accommodate believers in the divine Christ and the theory of evolution. This group believes that evolution is occurring, but that God created the start of all life.... [tags: evolution, organisms, creationism]

- Despite great efforts to convince the opposing side, a battle still brews amongst creationists and evolutionists over the beginning of life and the universe, but neither opinions’ palpability can be firmly upheld through scientific manners. Since science can only prove hypotheses that are testable and based on current observations, neither creation nor evolutionary concepts can be proven with irrefutable evidence. However, regardless of the inability to prove either concept, most public school systems promote evolution as a scientific fact.... [tags: Creation vs. Evolution Essays]

- It would be an understatement to claim that the realms of faith and reason rarely conflict. Since the earliest days of scientific inquiry, these two spheres of thought have been locked in a vicious battle, only letting up as religion has gradually modernized to accommodate newer understandings of the universe. But, as is the nature of any age-old debate, the fires fueling this conflict have once again been fed, this time with the controversy surrounding the teaching of Intelligent Design in public schools....

- The definition of the term ‘evolution’ summarized into one sentence refers to the changes in genetic traits or mutation between several generations. This change in genetic traits usually occurs during the breeding process, where the genes are copied passed on to the offspring. As a result the mutation, the genetic variation would occur between individuals. The new character/s could transfer within the specie due to the horizontal transfer of gene and migration. As the genetic variation/s become common between the specie through ‘natural selection’ or random genetic drift effect, evolution occurred to this specie....

- In Charles Darwin’s ‘Origin of Species’ the theory of evolution argues that the appearance of design in creatures are favourable chance mutations that have developed over time. Species have adapted to their habitats over a period, possessing many unfavourable traits that have slowly diminished over time due to not being able to survive in that particular environment (Darwin 1906: 97). Darwin’s theory has posed multiple problems for the Christian doctrine of creation, from the effect it has had on the concept of intelligent design to undermining the idea that humankind was made in the image of God....

- More and more scientists are daring to step away from evolution, as a basic argument for how life came to be and develop on the planet. It just does not hold water to explain how life started and develops. The conclusion favouring these scientists is intelligent design but at the moment this has not got the well thought out theories which evolution has. It is still in its early stages of understanding and requires far more research into what it means before it can be defined scientifically, it only can be said to imply there is a god or gods which made life and matter....

- There have been many ideas on the theory of evolution. Some simply take our existence for granted, others prefer to explain all evolution in terms of the bible and the presence of a God. However, there are those who have researched the topic of evolution and have offered an explanation as to where a species comes from and how they evolved in the manner that they did. This type of science has been studied for a very long time, and one of the most famous minds in the field of evolution was a man named Charles Darwin.... [tags: Natural Selection, Evolution Essays]

- "On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life," usually shortened to "the Origin of Species," is the full title of Charles Darwin's book, first published in 1859, in which Darwin formalized what we know today as the Theory of Evolution. Although Darwin is the most famous exponent of this theory, he was by no means the first person to suspect the workings of evolution. In fact, Charles owed a considerable debt to his grandfather Erasmus, a leading scientist and intellectual, who published a paper in 1794, calledZoonomia, or, The Laws of Organic Life....

- Evolution Theories explaining biological evolution have been bandied about since the ancient Greeks, but it was not until the Enlightment of the 18th century that widespread acceptance and development of this theory emerged. In the mid 19th century english naturalist Charles Darwin - who has been called the "father of evolution" - conceived of the most comprehensive findings about organic evolution ever1. Today many of his principles still entail modern interpretation of evolution. I've assessed and interpreted the basis of Darwin's theories on evolution, incorporating a number of other factors concerning evolutionary theory in the process.... [tags: Papers]
