i dont have much if any knowledge of this and was wondering if someone could explain this to me

Mitochondrial Eva is a common ancestor of all mankind correct?

does this mean that mankind went through this extreme bottleneck? or does it mean that its possible we all came from one woman?

I'm admittedly not well versed on the subject; But from what i do know, it all seems highly unlikely.

We may all be related through her not because of a bottleneck but because all later lineages died out. She and her "sisters" and "cousins" (because she wasn't a human in the homo sense) could all have had children and descendants for another many thousands of years, just their lineages all died out.

possibly a bottle neck...
but for consideration to understand this evolution and inheritance must be understood.
It may be as stated a few proto-humans which gave rise to the next...
or the one and her daughters (all having the same mitochondria)
gave rise to homo sapiens- where the rest of the tribe was homo erectus or something similar- all species show up somewhere as a mutation or variation of the surrounding like creatures.
so the primitive H.sapiens came from one mutation and here we see the link of that one change saved in the mitochondria of the first H.s...
there are other genetic markers in other animals showing lineage and a bottle neck or similar events
cheetahs for example all are more related than all humans are to each other
but that;s the gist so they call it the Eve story as we all derive from a single soure- and sadly the proto human 'adam' will never be identified

ok, this is what alot of people are saying but im having a problem with it alittle.

for us to be able to identify ME, wouldnt these lineages have to be COMPLETELY separate?



let me just illustrate this for a moment from the way im seeing it.

you have carmen.
carmen has (for the sake of simplicity) 2 daughters. eva and luisa.
eva and luisa both have many children for thousands of years (generations)

now basically what is being said is that we all are prodigy of eva. that luisa´s prodigy died out.

but lets say one of eva´s prodigy took a wife from one of luisa´s kin, luisa´s group dies off, but her M DNA would still live on correct?

i mean for all of us to be from eva´s kin, her kin would have to be in some way isolated.

am i mistaken?
