The best argument against evolution is the decline of all genomes, it’s devolution! The complexity and uniqueness for all genomes indicates an author of supreme ability and intelligence. Try randomly changing some computer code.
Consider that a perfectly designed new genome has no defects therefore sex between those closely related did not immediately lead to birth defects and other problems.
However, over thousands of years time we now use blood tests for those intending to marry to ensure these defects are not multiplied into more birth defects and quickening of devolution.
Sarah Palin is deeply saddened.
