Mоst оf the DNA sequence differences between species thаt diverge frоm eаch other do not involve significаnt changes in the protein-coding sequences of the genome, but rather, in the cis regulatory sequences of genes (enhancers). Describe two examples from this course which demonstrated this idea. WHY does evolutionary change through changes to the regulatory sequences provide an advantage over changes made to the protein-coding sequences of genes?
