Facts Of Evolution-The Molecules Of Life

FMost people do not really know what evolutionary science is; ... they rely on popular accounts, what someone else told them, or misconceptions, and base their beliefs on this erroneous information. It is difficult to even get a proper explanation if you look for it! Standard dictionaries are the worst place to look: "evolution: ...the doctrine according to which higher forms of life have gradually arisen out of lower.." - Chambers "evolution: ...the development of a species, organism, or organ from its original or primitive state to its present or specialized state; phylogeny or ontogeny" - Webster's These definitions are simply wrong! Unfortunately it is common for non-scientists to discuss evolution using just such definitions. When someone claims that they 'don't believe in evolution', they can't be referring to an acceptable scientific definition of evolution, because that would be denying something which is easy to demonstrate. It would be like saying that they don't 'believe' in gravity! The real problem is that the public, and creationists, do not understand what evolution is all about. Once we realize that evolution is simply "a process that results in heritable changes in a population spread over many generations" it seems a little silly to pretend that this doesn't happen!
