The main genetic marker for the Neolithic farmers is the female side mitochondrial DNA haplogroup H. A mitochondria is an organelle in the cell body which generates energy for the cell. Thus it only exists in the egg and from there it is transmitted to future offspring only by the mother.
Haplogroup H had frequency of 19% among Neolithic Early European Farmers and is virtually absent among Mesolithic European hunter gatherers. (Brotherton and all 2013)
Haplogroup H was also present in the Cucuteni–Trypillia culture. Nikitin and all (2017)
The clade has been observed among ancient Egyptian mummies excavated at the Abusir el-Meleq archaeological site in Middle Egypt, which date from the pre-Ptolemaic/late New Kingdom and Ptolemaic periods. Schuenemann and all (2017)
Additionally, haplogroup H has been found among specimens at the mainland cemetery in Kulubnarti, Sudan, which date from the Early Christian period (AD 550–800). Sirak (2016)
