Please, don't be too aggressive.I am just trying to make a sound argument here. Almost anything is possible, but it is very, very, very unlikely that Y-Adam and M-Eve lived at the same time. In addition, the evidence does not mean that either was the only one of their sex at the time. Finally, all the evidence points to bottleneck events where larger populations were reduced as opposed to founder populations. Anyone so limited that they can only spell a word one way is severely handicapped!

... with all the knowledge we have, there is no way "Adam" and "Eve" lived at the same time. Yes.But even "all the knowledge we have" today about ME and YcAdam cannot be considered sound knowledge. Isn't the knowldge we have about ME and YcA pretty primitive?

Yes. Both use a fundamentally similar methodology.

That's just inevitable. Humans are one species, everyone has a mother, and no-one has more than one mother. Given these facts, one can prove the existence of ME from one's armchair. Just curious ...Is it (theoretically) possible to have two MEs even though we are all a single species?

No, not really; I mean the calibration could be better, and we could collect more data but what we have is well supported. One thing that would indicate that our methods are fundamentally flawed is if YcA and ME came out as living at the same time or if YcA lived before ME.

We know absolutely nothing about "Adam" and "Eve". What we do know about are genetics. And everything we know about genetics says they did not live at the same time. If you have data that questions this finding, please present it. Until that time, there is no reason at all to question the outcome. Your preferred belief that they lived at the same time does not replace the data we do have that says they didn't.

No. At most we could share a ME who isn't human. In theory we could trace that ME right back to the dawnings of sexual reproduction but the odds against that are so high as to mean it's practically certain not to be the case.

The Theory of Evolution does not contradict that statement. The evidence of evolution does contradict it.I may be wrong but my understanding of evolution does not contradict the statement: "All human beings are descendants of Adam." The Australian Aborigines were already in Australia well before the time of Adam and Eve. If you read Genesis without prior doctrinal commitment, it comes across quite clearly that the A&E story is a "Just So" story, a kind of fable, and never intended as history.

Is it (theoretically) possible to have two MEs even though we are all a single species? I'm going to slightly disagree with Mr. Jack here and say that we could but not at the same time. The coalescence for Mitochondrial eve is around ~170,000 years based on the distribution of modern mitochondrial genotypes, if we were able to go in a time machine back a few 10's of thousands of years and do a similar experiment with that population of humans we might identify a different mitochondrial eve at a different coalescence point. Although as Mr. Jack points out, at some point that ancestor is not themselves going to be of the species Homo sapiens sapiens By definition any given population can only have 1 mitochondrial eve at a time since the whole point is that ME is the common matrilineal ancestor, if there is more than one candidate genome then you haven't gone back far enough and aren't looking at the common ancestor. The human race could even have a different mitochondrial eve in the future since novel mitochondrial genotypes are being produced all the time and in the right circumstances one of these could reach fixation. There is a simulation on a site hosted by the North Carolina state university showing how a mixture of maternal mitochondrial genotypes resolve down to one as the result of random sampling.

Is it (theoretically) possible to have two MEs even though we are all a single species? Mitochondrial Eve is by definition our most recent common ancestor in the female line. There can only be one of those. This is not to say that you'd have noticed anything special about her at the time. She's unique because she's been carefully defined so as to be unique.

It's worth noting that every little chunk of our genome has its own most recent common ancestor, not just mitochondrial DNA and the Y chromosome. Most of these ancestors lived much longer ago than ME or Y-Adam -- typically on the order of half a million or a million years ago.

Huntard writes: she is just the only woman with an unbroken female line until the present day. You are overstating the uniqueness of ME. ME is merely the most recently born ancestor of all of us. ME's mother and ME's mother's mother would each be in the same unbroken line.

quote: You are right, but not for the reasons you give. ME is not our oldest female common ancestor. She is instead our most recent common ancestor. Assuming the Bible to be correct regarding the creation of Adam, we would not expect mitochondrial Eve to be the Biblical Adam's mate. ME might have been born any number of generations after Biblical Eve died. Edited by NoNukes, : No reason given.

Except that mitochondrial eve lived at least 70000 years before the so called biblical eve would have lived.
From the Ancestor's Tale:
And indeed, today's best 'molecular clock' estimates for their respective dates are about 140,000 years ago for [mito]Eve and about 60,000 for [y-chrome]Adam. There is no better love between 2 people than mutual respect for each other WT Young, 2002 Who gave anyone the authority to call me an authority on anything. WT Young, 1969 Since Evolution is only ~90% correct it should be thrown out and replaced by Creation which has even a lower % of correctness. W T Young, 2008
