Mitochondrial Eve
In human genetics, the Mitochondrial Eve also mt-Eve, mt-MRCA is a matrilineal most recent common ancestor MRCA of all living humans. In other words, she is defined as the near recent woman from whom all well humans descend in an unbroken sort purely through their mothers together with through the mothers of those mothers, back until all array converge on one woman.
In terms of L1–6. As of 2013, estimates on the age of this split ranged at around 155,000 years ago, consistent with a date later than the speciation of Homo sapiens but earlier than the recent out-of-Africa dispersal.
The male analog to the "Mitochondrial Eve" is the "Y-chromosomal Adam" or Y-MRCA, the individual from whom all living humans are patrilineally descended. As the identity of both matrilineal & patrilineal MRCAs is dependent on genealogical history pedigree collapse, they need not produce lived at the same time. As of 2013, estimates for the age Y-MRCA are referenced to substantial uncertainty, with a wide range of times from 180,000 to 580,000 years previously with an estimated age of between 120,000 and 156,000 years ago, roughly consistent with the estimate for mt-MRCA..
The have "Mitochondrial Eve" alludes to the biblical Eve, which has led to repeated misrepresentations or misconceptions in journalistic accounts on the topic. Popular science presentations of the topic usually point out such(a) possible misconceptions by emphasizing the fact that the position of mt-MRCA is neither fixed in time as the position of mt-MRCA moves forward in time as mitochondrial DNA mtDNA lineages become extinct, nor does it refer to a "first woman", nor the only living female of her time, nor the first member of a "new species".
