Recommended: Charles Darwin’s theory of evolution and adaption
The theory of evolution is a very interesting, but also a bit of a controversial topic. The Merriam Webster dictionary defines evolution as “a theory that the differences between modern plants and animals are because of changes that happened by a natural process over a very long time.” Even though many people would and have disagreed with this following statement, the theory of evolution as of now is the best the best way of explaining why people and the animals which are, are on earth today.
Like all scientific discoveries the theory of evolution had to be discovered by someone, and this someone’s name was Charles Darwin. Charles Darwin was an English biologist who was born in 1809; he was also a writer and known to be the father of biology. The following is based on the book “The Natural History of the Galapagos,” written by Ian Thornton. Darwin came up with the theory of evolution after he had spent time in the Galapagos Islands. While he was in the Galapagos Islands Darwin had noticed a specific breed of birds, these birds were known as the Galapagos Finches. What Charles had specifically noticed about the Galapagos finches was that the finches were made up of many different species; it was obvious that these birds were all related but each species had a specific variation. For example the birds would have different sized or shaped beaks. From this Darwin noticed that each separate groups of finches had separate habits, specifically eating habits. Charles noticed that the species which he referred to as ground finches were designed to obviously feed on what they could mainly find on the ground such as seeds and insects, also that the tree finches were designed to feed off of higher ground. Finally from all of this he was ...

Darwin did not come up with his theory out of nowhere. Like anyone else who has made discoveries, he was influenced by others. For quite a long time before Darwin, people didn't look beyond the Biblical creation story. Such things as fossils, primitive stone tools and visible layers in rock were said to have been placed on earth by God. There wasn't a great deal of work done on what we now call evolution, until the age of exploration began. Around that time people noticed that there were different types of humans in different parts of the world. There were several attempts to classify the various types of humans, but such classifications were generally extremely ethnocentric, and included ideas that have been proved incorrect. For a time people believed that creatures like Dr. Moreau's Beast People could and did exist in the world; explorers told fantastic tales of humans with the heads of dogs, or mermaids, or islands populated by only humans of only one gender. In the seventeenth century John Ray coined the term "species," but he believed that none of the species had changed since the day of creation. Linnaeus, who invented the system of binomial nomenclature used today to classify different species, was also a creationist.
Charles Darwin was an English biologist who, along with a few others, developed a biological concept that has been vulgarized and attacked from the moment his major work, The Origin of Species, was published in 1859. An accurate and brief picture of his contribution to biology is probably his own: Evolution is transmission with adaptation. Darwin saw in his epochal trip aboard the ship The Beagle in the 1830s what many others had seen but did not draw the proper conclusions. In the Galapagos Islands, off South America, Darwin noted that very large tortoises differed slightly from one island to the next. He noted also that finches also differed from one geographical location to the next. Some had shorter beaks, useful for cracking seeds. Some had long, sharp beaks, useful for prying insects out of their hiding places. Some had long tail feathers, others short ones.
What is evolution? Evolution in modern terms is fairly easy to understand. Evolution is the theory that life on earth began with a single celled organism that lived more that 3.5 billion years ago that slowly evolved into many diverse creatures over time. When you break down this theory into sections you get 6 factors: evolution, gradualism, speciation, common ancestry, natural selection and nonselective mechanisms of evolutionary change.
of ideas and predetermined extractions from other already written short texts on evolution. Still, what is evolution? Evolution is the change in the inherited characteristics of biological populations over successive generations (N.A.), but is it a belief, dependent and trusted on and through faith, or is it a science; a proven, cold hard fact, which is observable and repeatable? Many, if not all, evolutionists would say that it is the latter, ...
There are many different theories as to what evolution is, but they all conclude that evolution is a change in species over time. The modern theory of evolution is based on the concept of natural selection. Natural selection is the metapho...
What is evolution and how does it work? Evolution is the theory of how one form of life changes into another form. Evolution also is the change of a population’s inherited traits from generation to generation. Evolution helps to explain why an animal, human, and plant looks the way it does and acts the way it does; it gives an explanation of the history of life. Genes come in many varieties and the evolution helps to make it happen. Mutation, natural selection, genetic drift, and gene flow: the four forces that make the evolution work.
Charles Darwin came up with the theory of evolution and used the term natural selection to describe it. He proposed that all living species derived from a common ancestor. In On the Origin of Species (1859), Darwin explained: “if variations useful to any organic being do occur, assuredly individuals thus characterised will have the best chance of being preserved in the struggle for life; and from the strong principles of inheritance, will then tend to produce offspring similarly characterised” (p127).
While the theory of evolution is very commonly accepted amongst most scholars and intellectuals, when the scientific facts used to 'support' it are closely examined, it becomes apparent that it is merely that: a theory. Inaccurate information, misguided philosophers, and in some cases, just plain ignorance, have all contributed to this 'scientific religion' that does nothing but lead people away from the true nature of our existence, the Genesis creation. The creation 'story' is much more than just a story, it is a scientifically provable fact, and one that should be treated as more than just a parable or story, as the Word of God is pure and the absolute truth.
The facts and research on evolution is so important in our wold today that we all must really understand it. Correctly understanding evolution is crucial for understanding biology as well. Scientist Theodosius Dobzhansky said, “Nothing in biology makes sense except in the light of evolution.” Evolution proves to be the only scientifically backed up explanation for human diversity. It shows us the connection between vastly different forms of life. As well as showing the changes and evolution of popul...
The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence ("Evolution Resources from the National Academies"). The idea of evolution is a widely accepted theory around the world; there are people who still hold their religious and often bronze aged ideas to explain how the life on earth started and continued. In a creation versus evolution debate, these ideas may help you explain evolution.
The evolutionary theory is the concept that species evolve over time through the mechanism of natural selection of survival and reproduction. Natural selection means acting on the assumption that various living organisms were produced by genetic diversity and mutation. The evolution theory may also be referred to as the philosophizing science. This theory states that all phenomena are derived from natural causes and can be explained by scientific laws without reference to a plan or purpose.
The Galapagos Island has a natural treasure of a distinct ecosystem because of various endemic species. As a result of the significant environmental and ecological characteristic of the Galapagos Island, it stimulates the development of sustainable ecotourism industry. Accounting to observe and collect the important information about the unique species which cannot find anywhere else on Earth, this inspiring Charles Darwin to form his famous theory of evolution by natural selection. However, similar with other isolated islands, the Galapagos Islands also face some serious challenges about their ecosystems for introduced species, fishing and human impacts. On the other hand, the development of ecotourism is beneficial to Galapagos residents

One of the greatest questions of all time is: "Where the heck did we come from?" One of the most popular answers to this question is creationism, the idea that everything was created by a higher being. Another idea is evolution, the idea that all living organisms descended from a less complex organism. Up and coming in the last century, evolution possesses a new way of thinking that is being greatly accepted by the scientific community. Despite this fact many people argue that evolution has no facts to support it and there are several reasons why evolution can't happen.
Evolution is the scientific theory of the development of living organisms during their period on earth. The theory takes into consideration the biological processes of natural selection, mutation, symbiosis, gene transfer and genetic drift.
