Mitochondrial Eve .....




Mitochondrial Eve


my notes:


I love to incorporate history, mythology etc within my creations...so I research alot ...

I need to create and via my findings I try to send a spiritual message through my work - it may not always be clear , but it is present...created by the procedure itself.......



I have an interest in the Picts (although not a great deal is known) I mention this because they followed Matrilineality

( a system in which lineage is traced through the mother and maternal ancestors) ...

I feel a connection to the feminine, goddess and for a group of people to follow this method inspires me.



It was interesting that we discovered Mitochondrial Eve...and how far apart she was from y chromosomal Adam....we all derived from her...the female ... it makes sense the old ways of appreciation for the mother...the female deity...goddess....giver of life....the goddess statues unearthed....

We had forgotten the information over time...now it is beginning to re-earth....



Below is a scientific explanation of Mitochondrial Eve :



Mitochondrial Eve is the name given by researchers to the woman who is defined as the matrilineal most recent common ancestor (MRCA) for all currently living humans. Passed down from mother to offspring, her mitochondrial DNA is now found in all living humans: every mtDNA in every living person is derived from hers. Mitochondrial Eve is the female counterpart of Y-chromosomal Adam, the patrilineal most recent common ancestor, although they lived at different times.


She is believed to have lived about 140,000 years ago in what is now Ethiopia, Kenya or Tanzania.


All living humans can trace their ancestry back to the MRCA via at least one of their parents, but Mitochondrial Eve is defined via the maternal line.

Therefore, she necessarily lived at least as long, though likely much longer, ago than the MRCA of all humanity.
The existence of Mitochondrial Eve and Y-chromosomal Adam does not imply the existence of a first couple.


They each may have lived within a large human population at a different time.


To find the Mitochondrial Eve of all living humans, one can start by tracing a line from every individual to his/her mother, then continue those lines from each of those mothers to their mothers and so on, effectively tracing a family tree backward in time based purely on mitochondrial lineages.


Going back through time these mitochondrial lineages will converge when two or more women have the same mother. The further back in time one goes, the fewer mitochondrial ancestors of living humans there will be.


Eventually only one is left, and this one is the most recent common matrilineal ancestor of all

humans alive today, i.e. Mitochondrial Eve.


It is possible to draw the same matrilineal tree forward in time by starting with all human female contemporaries of Mitochondrial Eve.


Some of these women may have died childless. Others left only male children. For the rest who became mothers with at least one daughter, one can trace a line forward in time connecting them to their daughter(s).


As the forward lineages progress in time, more and more lineage lines become extinct, as the last female in a line dies childless or leaves no female children. Eventually, only one single lineage remains, which includes all mothers, and in the next generation, all people, and hence all people alive today.


Mitochondrial Eve is the most recent common matrilineal ancestor, not the MRCA of all humans. The MRCA's offspring have led to all living humans via sons and daughters, but Mitochondrial Eve must be traced only through female lineages, so she is estimated to have lived much longer ago than the MRCA (In genetics, the most recent common ancestor (MRCA) of any set of organisms is the most recent individual from which all organisms in the group are directly descended)


important note:


Mitochondrial Eve is estimated to have lived about 140,000 years ago. Y-chromosomal Adam is estimated to have lived around 60,000 years ago.
