To avoid semantic misunderstanding, lets consider some definitions. The word evolution, could technically speaking refer to practically anything, since so many things can evolve one way or the other. However when most people use the word evolution without clarifying which evolution they are referring to, they usually mean "the evolution of the different species". I can understand why people would simply say "evolution" for practical reasons, but that is somewhat confusing. Because of this, many people think that the the term "evolution of the different species" refers to exactly the same as "biological evolution". I would disagree and say that although the evolution of the different species is indeed a part of biological evolution, the term biological evolution entails a lot more than just that.<ul> <li data-xf-list-type="ul">Biological evolution.</li> </ul>This general term can be split up into two separate theories: <ul> <li data-xf-list-type="ul">Evolution of life out of lifeless matter a.k.a. abiogenesis.</li> <li data-xf-list-type="ul">This is the theory on how the first biological life evolved out of lifeless matter on earth.</li> </ul>Evolution of the different species a.k.a. origin of the different species. This is a group name for several other theories such as the theory of genetic mutation, survival of the fittest, genetic drift, and so on. These theories can be mainly categorized into three segments: <ul> <li data-xf-list-type="ul">The theory of micro evolution.</li> </ul>How genetic drift trough variation and mutation creates new breeds of a certain specie that then grow larger in numbers trough survival of the fittest. The theory of macro evolution.How mutations on a genetic level can cause new species. <ul> <li data-xf-list-type="ul">The theory of common descent.</li> </ul>How trough micro and macro evolution, all existing creatures evolved out of the same ancestral  being. This is not a scientific theory but a historical one. In other words it doesn't tell us something about the nature of physics, or the physics of nature, instead it speculates on how the currently existing organisms have evolved in the past.<a href="http://seemyparadigm.webs.com/evolution.htm" target="_blank">more....</a></blockquote>
