NUMT, pronounced "new might," is an acronym for "nuclear mitochondrial DNA" segment coined by evolutionary geneticist, Jose V. Lopez, which describes a transposition of any type of cytoplasmic mitochondrial DNA into the nuclear genome of eukaryotic organisms. In 2022, scientists reported the discovery of ongoing transfer of mitochondrial DNA into DNA in the cell nucleus. Previously, NUMT were thought to have arisen only long ago. 66 thousand whole-genome sequences indicate this currently occurs as frequent as once in every ~4,000 human births.
