  • Because genomes are products of natural processes rather than “intelligent design,” all genomes contain functional and nonfunctional parts. The fraction of the genome that has no biological function is called “rubbish DNA.” Rubbish DNA consists of “junk DNA,” i.e., the fraction of the genome on which selection does not operate, and “garbage DNA,” i.e., sequences that lower the fitness of the organism but exist in the genome because purifying selection is neither omnipotent nor instantaneous.
