answer The main tenet of the neutral theory is that the great majority of evolutionary changes at the molecular level are caused not by Darwinian selection but by random fixation of selectively neutral or very nearly neutral alleles through random sampling drift under continued mutation pressure The theory also asserts that the majority of protein and DNA polymorphisms are selectively neutral and that they are maintained in the species by mutational input balanced by random extinction rather than by balancing selectionThe neutral theory claims that the great majority of evolutionary changes at the molecular DNA level are caused not by Darwinian selection but by random fixation of selectively neutral or nearly neutral mutants The theory also asserts that the majority of protein and DNA polymorphisms are selectively neutral and that they See Answer
