Evolution is the change that species undergo over time. To be more specific, evolution is the change in the gene pools of living populations of species which occurs over time. A hereditary unit that can be passed on unaltered for many generations is a gene and the set of all genes in a species or population is the gene pool. The first point stated by the theory of evolution, and possibly the most important, is that all life forms have developed from other species. It also states that all living things are related to one another to different degrees and that they all share common ancestors. The third point is that all life on Earth has a common origin. To make it simpler, all life arose from a once existing original life form. The process by which one species evolves into another requires genetic mutations, or changes, is the fourth and final statement in the theory of evolution. In order for evolution to occur, three main mechanisms must occur, natural selection, genetic drift, and mutation. Natural selection is the process by which traits that provide a reproductive advantage tend to increase in frequency in a given species over time. Also, traits that put individuals at a disadvantage most likely decrease over time. Genetic drift is the process in which traits change over time merely by chance, as to predetermined change in natural selection. A mutation is any change in the DNA base sequence of a gene, which occurs in both natural selection and genetic drift. Evolution can be found in fossil records and chemical and structural similarities. Genetic changes over generations and geographic distribution of related species are also two great pieces of evidence supporting the theory of evolution.
Probably the most popular evidence for evolution is the numerous fossils found over time. The remains of plants and animals found in sedimentary rock deposits give scientists an indisputable record of past changes through time.
What is evolution? ... Evolution also has two subunits which can be divided into micro evolution and macro evolution. The kind of evolution documented above is micro evolution. ... I think the difference between the two is senseless because macro evolution is cumulative micro evolution. ... The word evolution has many different meanings. ...
Evolution The origins of mankind is an extremely controversial issue within today's society. ... One such argument is the conflict involving the theory of evolution versus the theory of creation. After extensive scientific research, it is apparent that the theory of evolution is correct. ... Similarities in these categories link species together and are therefore studied to support evolutionism. ... Darwin proposed that evolution occurred as the result of natural selection. ...
Discussion Assignment # 2, Topic 2 Conflicts between scientists and nonscientist's beliefs of evolution are nothing new to the scientific community. Scientists spend years solely on the research of evolution theories to provide evidence for evolution. This enables them to present facts and defend evolution as a truth. However, showing clear-cut evidence to a nonscientist that evolution exists still presents a major problem. ... Archeological fossils have been found that creates some evidence that points to more or less evolution. ...
Today's human being is the product of millions of years of trial and error through the process of evolution. Charles Darwin was the first to bring fourth the idea of evolution. ... Evolution is the most logical explanation for mans place on earth. ... Almost all scientists believe in some sort of evolution, though they may not agree on all the details they all agree that evolution is the reason for mans place on earth. ...

The Theory of Evolution The theory of evolution creates tremendous controversy in today's society. Anything as controversial as the creation/evolution debate is bound to generate a diversity of opinions. ... I believe the theory of evolution should be banned from educational courses because of religious conflict. ... Much evidence can be provided against the theory of evolution. ... Evolution supports the idea that humans and apes evolved from a single common ancestor. ...
Creationists say that the evolution theory is biased and incomplete. ... The process of evolution, which all living things developed from unicellular organisms, over billions of years Exactly how evolution occurs is still debated but it is a scientific fact that it does occur. ... Evolution apparently has no built-in direction or purpose. ... It is clear that evolution is much clearer to understand and accept than the creationism theory.
