MtDNA
Les mitochondries sont des organites présents dans la grande majorité des cellules eucaryotes qui seraient issues de l'endosymbiose d'une alpha-protéobactérie, il y a environ deux milliards d'années (Théorie endosymbiotique).
Au cours de l'évolution, les mitochondries ont conservé leur propre génome, qui, bien que très réduit par rapport à celui d'une bactérie, est essentiel au bon fonctionnement de ces organites. Confiné à l'intérieur des mitochondries, organites qui produisent l'énergie cellulaire, le génome mitochondrial (ADNmt) est distinct de l'ADN contenu dans le noyau . La transmission de cet ADN est généralement dite non mendélienne, dans la plupart des cas, il est transmis par la mère. Mais il existe de nombreuses exceptions chez les plantes, les champignons et même chez les animaux .
Le génome mitochondrial est particulièrement utilisé en génétique des populations humaines, ou en agronomie, comme marqueur génétique pour la biologie évolutive (« marqueur direct et non ambigu de la généalogie maternelle et de la structuration géographique au sein d’une espèce, ainsi que des échanges génétiques entre populations, entre sous-espèces »). Il se distingue du reste du génome des cellules eucaryotes par son asexualité, qui est à l'origine du phénomène de « stérilité mâle cytoplasmique ».

Dienekes’ Anthropology Blog: Ancient mtDNA haplogroup M from Syria
This is quite an unexpected finding; there has been a paucity of ancient DNA from the Middle East, perhaps due to a combination of high temperature, less scientific development, and well-known recent problems in many parts of the region, and it would be great if additional research in the area is possible. PLoS ONE 8(9): e73682.
