The [[genetic entropy]] theory by [[Cornell University]] Professor Dr. [[John Sanford]] on eroding [[genome]]s of all living organisms due to [[mutations]] inherited from one generation to the next is declared to be one of the major challenges to [[evolutionary theory]]. The central part of Sanford’s argument is that mutations, represented by spelling mistakes in [[DNA]], are accumulating so quickly in some creatures (and particularly in people) that [[natural selection]] cannot stop the ''functional degradation'' of the genome, let alone drive an evolutionary process that could lead for example, from apes into people.<ref>{{cite web | The [[genetic entropy]] theory by [[Cornell University]] Professor Dr. [[John Sanford]] on eroding [[genome]]s of all living organisms due to [[mutations]] inherited from one generation to the next is declared to be one of the major challenges to [[evolutionary theory]].
