 Some researchers assumed that the C-value paradox was fully resolved by the recognition that there is non-coding DNA in genomes (Gregory 2001). Larger genome size in ‘simpler’ organisms merely means that they have large quantities of non-coding DNA. But as Gregory points out, the fact that the majority of DNA in our genomes is non-coding might make the C-value discrepancies less of a paradox, but it gives rise to a whole range of further puzzles (Where does this extra DNA come from? What is its function? Etc.), which is why he proposes to talk of the C-value as an enigma rather than a paradox (Gregory 2001). The C-value enigma consists of many different and layered problems and these require a pluralistic approach to answering them, or so Gregory claims.
