Molecular biology, contrary to the article, does not support evolution by natural chance because evolution can not occur without inheritance, inheritance can not occur without DNA and DNA is so complex it could not have evolved by chance unless we are to assume that molecules just happened to arrange themselves into the DNA molecule at the same times as a nucleus formed to hold the DNA, at the same time as the cell membrane just happened to form around it, at the sametime as all the cell maintaining process in the cytoplasm just happened to come into existence to form a single cell and that all these aspects just happened to come together and work harmoniously.
