Our genome is littered with scraps of DNA, termed 'junk' DNAs, that serve no apparent purpose. Junk DNAs make up as much as 98.5 per cent of our genome. Scientists believe that some junk DNAs came into existence millions of years ago, when viruses inserted their DNA into that of the human host. This book offers various answers.
