Girls looking for sex Hazleton Simplified Human mitochondrial phylogeny The mitochondrial clade which Mitochondrial Eve defines is the species Homo sapiens sapiens itself, or at least the current population or " chronospecies " as it exists today.
In principle, earlier Eves can also be defined going beyond the species, for example one who is ancestral to Adult online chat hill cam sex cutie modern humanity and Neanderthalsor, further back, an "Eve" ancestral to all members of genus Homo and chimpanzees in genus Pan.
According to current nomenclature, Mitochondrial Eve's haplogroup was within mitochondrial haplogroup L because this macro-haplogroup contains all surviving human mitochondrial lineages today, and she must predate the emergence of L0.
The variation of mitochondrial DNA between different people can be used to estimate the time back to a common ancestor, such as Mitochondrial Eve.
This works because, along any particular line of descent, mitochondrial DNA accumulates mutations at the rate of approximately one every 3, years per nucleotide. At the same time some branches, including even very old ones, come to an end when the last family in a distinct branch has no daughters. Mitochondrial Eve is the most recent common matrilineal ancestor for all modern humans.
There's no such thing as a 'pure' European—or anyone else | Science | AAAS
Whenever one of the two most ancient branch lines dies out, the MRCA will move to a Ladies seeking sex Penacook New Hampshire recent female ancestor, always the most recent mother to have more than one daughter with living maternal line descendants alive today.
The of mutations that can be found distinguishing modern people is determined by two criteria: firstly and most obviously, the time back to her, but secondly and less obviously by the varying rates at which new branches have come into existence and old branches have become extinct.
By looking at the of mutations which have been accumulated in different branches of this family tree, Looking for fun over Michigan looking at which geographical regions have the widest range of least related branches, the region where Eve lived can be proposed.
