First, I would like to say that I am a scientist and I do believe in the theory of evolution. This does not, however, mean that I do not believe in a God, or Supreme Being. Many scientists who believe in the theory of evolution are also devout religious people. Second, I would like to say that before you say something like "the idea of evolution is BS," you should really learn more about what you are talking about. I will do my best to enlighten you on Darwin's theories.
Darwin's theory of evolution is now over 130 years old. Darwinism encompasses several different, although mutually compatible, theories. Many respectable scientists argue that Darwinism should be viewed as five major theories. These five theories have somewhat different origins and different fates and cannot be discussed accurately as if they were only a single statement. The theories are: 1. Perpetual change 2. Common descent 3. Multiplication of species 4. Gradualism 5. Natural selection
The first three theories are genearlly accepted as having universal application throughout the living world. The theories of gradualism and natural selection are controversial among evolutionists. Gradualism and natural selection are clearly part of the evolutionary process, but they might not be as pervasive as Darwin thought. Legitimate controversies regarding gradualism and nautral selection often are misrepresented by creationists as challenges to the first three theories, whose validity is strongly supported by all relevant facts.
1. Perpetual Change. This is a basic theory of evolution on which the others are based. It states that the living world is neither constant nor perpetually cycling, but is always changing. The properties of organisms undergo modification across generations throughout time. Perpetual change is documented by the fossil record, which clearly refutes creationists' claims for a recent origin of all living forms. Because it has withstood repeated testing and is supported by an overwhelming number of observations (fossil records, etc.), we now regard perpetual change as a scientific fact.
2. Common Descent. The second Darwinian theory, common descent, states that all forms of life descended from a common ancestor through a branching of lineages. The opposing argument, that the different forms of life arose independently and descended to the present in linear, unbrached genealogies, has been refuted by comparative studies of organismal form, cell structure, and macromolecular structures (including those of the genetic material, DNA). All of these studies confirm the theory that life's history has the structure of a branching evolutionary tree. Species that share relatively recent common ancestry have more similar features at all levels than do species that have only an ancient common ancestry.
3. Multiplication of Species. Darwin's third theory states that the evolutionary process produces new species by the splitting and transformation of older ones. Species are now generally viewed as reproductively distinct populations of organisms that usually but not always differ from each other in organismal form. Once species are fully formed, interbreeding does not occur among members of different species. Evolutionsists generally agree that the splitting and transformation of lineages produce new species, although much controversy remains concerning the details of this process and the precise meaning of the term "species".
4. Gradualism. Darwin's theory of gradualism states that the large differences in anatomical traits that characterize different species originate by accumulation of many small incremental changes over very long periods of time. This theory opposes the notion that large anatomical differences arise by sudden genetic changes. This theory is important because genetic changes having very large effects on the organism are nonethless sufficiently beneficial to be favored by natural selection. Therefore, although gradual evolution is known to occur, it may not explain the origin of all structural differences that we observe among species.
5. Natural selection. Natural selection explains why organisms are constructed to meet the demands of their environments, a phenomenon called adaptation. This theory describes a natural process by which populations accumulate favorable characteristics throughout long periods of evolutionary time. Adaptation was viewed previously as strong evidence against evolution. Darwin's theory of natural selection was therefore important for convincing people that a natural process, capable of being studied scientifically, could produce new adaptations and new species. Demonstration that natural processes could produce adaptation was important to the eventual acceptance of all five Darwinian theories. Darwin developed his theory of natural selection as a series of five observations and three inferences from them:
Observation 1: Organisms have great potential fertility. Observation 2: Natural populations normally remain constant in size, except for minor fluxuations. Observation 3: Natural resources are limited. Inference 1- There exists a continuing struggle for existence among members of a population. Observation 4: All organisms show variation. Observation 5: Variation is heritable. Inference 2- There is differential survival and reproduction among varying organisms in a population. Inference 3: Over many generations, differentieal survival and reproduction generate new adaptations and new species.
In summary, the fact that these theories have been around for over 130 years and are continuing to be validated and confirmed by new technology and observations, I believe, is proof enough that the statement "the idea of evolution is BS" is not only ignorant, but false. At the same time, evolution does not discount the idea of a God or Supreme Being. In the second part of Darwin's theory, "common descent," he propsed that all plants and animals have descended from "some one form into which life was first breathed." Thus, believing in evolution does not mean you do not believe in God.
