Why don't the writers on this subject include contradictions, arguments and mistakes in regards to evolution theory. I will be very disappointed if Wiki is bias or one side. Thank You

That's because from a scientific standpoint, there are no major substantiated contradictions and mistakes in evolutionary theory, and the minor or unsubstantiated issues do not belong in an overview article. There is a brief discussion of the "arguments" as presented from a non-scientific perspective in this section and related articles: Evolution#Social_and_cultural_responses. Essentially, the point is that the article covers the science and theory of evolution, and not random objections presented by non-experts without scientific backing. This is not seen as a bias within Wikipedia's rules, as it is a policy to cover scientific subjects from a scientific perspective, and discuss secondary or sociological impacts separately from the actual content. 162.111.235.36 (talk) 19:22, 10 July 2012 (UTC)Reply
