text: Researchers probed the feedback networks that regulate these mechanisms, first in viruses and bacteria, then in complex, multicellular organisms; mapped and modified the specific DNA sequence of organisms; compared sequences among taxonomic groups (i.e., groups in different branches of the classification of life) so as to assess the degree of genetic variation in populations and to classify taxonomic groups into phylogenies; traced where and when in development specific genes are active; and examined the role of DNA sequences not associated with genes (Griffiths & Stotz 2013).
