Research Suggests One To Three Men Fathered Most Western Europeans
Taco Cowboy writes "'While the distribution of Y-chromosome haplogroups in Africa took 12 thousand years to spread, those in Europe started from around 3rd millennium.' The speed of spread of the European haplogroups was totally astounding, to say the least. 'There was no R1b found in Europe before a Bell Beaker site from the 3rd millennium BC and today many Europeans (most in western Europe) belong to this haplogroup. 'We used coalescent simulations to investigate the range of demographic models most likely to produce the phylogenetic structures observed in Africa and Europe, assessing the starting and ending genetic effective population sizes, duration of the expansion, and time when expansion ended. The best-fitting models in Africa and Europe are very different. In Africa, the expansion took about 12 thousand years, ending very recently; it started from approximately 40 men and numbers expanded approximately 50-fold. In Europe, the expansion was much more rapid, taking only a few generations and occurring as soon as the major R1b lineage entered Europe; it started from just one to three men, whose numbers expanded more than a thousandfold.'"
This proves it! Noah and his sons have been found through genetics.
What now atheists? You better hope it doesn't flood again.
Article seems to indicate itself as source .... Selfy !
...your mother.
In regards to the constant bickering and wars, it all makes sense! Three families? That is a shit ton of brothers fighting over stupid shit
Isn't this really what this is all about? Not the research, but **why** the research is noteworthy...
There are **alot** of people who believe the Torah, New Testament, etc not as litteral truth but as mythology which can represent truthful stories under a layer of abstraction.
I don't believe science can prove OR disprove a god or buddah or FSM or anything beyond the natural world. Supernatural is unprovable scientifically by definition....**super** natural.
Why not talk about the mythology?
Are we projecting (because the Noah story is still widely told) onto this finding if we compare it to the Torah's account of Noah and the repopulation of the world after?
There are several ancient maps showing **very testable** notions of population distribution. If these are anywhere near accurate in explaining human population distribution why not do more science based on it?
Is anyone really concerned about proving god exists somehow? what's the downside if the ancient mythology correlates with modern science?
Thank you Dave Raggett
Must have been quite a night!
The truth comes out. Most of you are a bunch of inbred bastards.
Dang modern science, guys, they found us! It'll only be a matter of time before they round us up. I mean, it's not like you all should be GRATEFUL to your elders but NO
Actually the neanderthal DNA is primarily in Europeans.
Wow, sent an e-mail as suggested when clicking on "use classic" banner, and got a fast response that addressed my msg
Which may be because the neanderthal people were primarily in Europe.
The Tao of math: The numbers you can count are not the real numbers.
* Bell Beaker site mentioned in summary but not in quoted article.
* Summary says R1b entered after 3rd millienium BC. Quoted article says the European expansion took place roughly 12000 years ago:
In Europe, the expansion was very rapid, taking only approximately 325 (50 to 600) years and ending approximately 12 (6 to 14) KYA,...
No mystery there. The last glacial period ended about 12000 years ago, turning much of Europe from a hard place to live to a much easier place to live. People moved in and expanded greatly.
I'm not playing this game...
define "believe"...
I watch Fox News...when Stephen Colbert is parodying it...but I watch what is happening just like anything else, analyzing and processing it...Fox News is ridiculous!
But I can't say I've never watched it...even in the course of parody...and I've seen that **sometimes** not **everything** they do is bullshit. I've seen a few clips where Colbert or John Stewart are actually giving respect to Fox News and makign fun of someone else.
In that same way, I "believe" what I see as true in **any** text...
So...that's where I'm coming from...I want to know how **YOU DEFINE BELIEVE**
If you want to have a value-added conversation you have to start there...what do you mean by "believe"?
Thank you Dave Raggett
Complete mischaracterization. What the article says is that there was an African expansion from a smallish group in West Africa that spread out and populated most of the continent and that Europe was colonized really quickly in the aftermath of the latest glaciation by people rpobably from the middle east.
The African expansion took longer because there were more people there to compete with the expanding group.
Wow, his bunga-bunga parties must really draw a lot of women!
The mystery of the origin of the Indo-Europeans may be solved within the next 2 years , and yes I know Discover is not a peer reviewed journal.
The timeframe is correct for the supposed origin of indo europeans in Europe.
If your children ever found out how lame you are, they'd murder you in your sleep
if you're going to talk about Mythology you should get it right.
the Torah records **8** humans aboard the ark...Noah, his three sons Ham, Shem, and Japheth...and all of their wives.
this is the problem...people who talk about things they know nothing about...these kinds of comments only give fuel to the people trying to put Young-Earth Creationism into textbooks in Kansas...
get it right for fucks sake....**we're** supposed to be the scientific side of the debate!!!
is 8 people enough genetic material? who cares? it wont prove or disprove anything to anyone...
TFA is real science...trying to prove or disprove Mythology is not science
Thank you Dave Raggett
Going back far enough you only have one man and one woman that are the basis for Homo Sapiens.
But they may never have met - the lineages for males and females have been on different paths. All the variations we see are from mutations, and maybe in some cases DNA exchange through viruses.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.
Seriously, that's all that they had, so procreation was the only entertainment.
The problem with claiming that all Europeans came from a small number of people based upon a Y-chromosome study is that such a study, by design, misses many men who failed to leave male descendants. If, for example, I have four children, but they are all daughters, then my Y chromosome dies with me, even though many other of my genes will still live on in my daughters (in aggregate, if I had four children, around 94% of my genes would survive into the next generation).
This means that over time, we lose the Y chromosomes of many ancestral men just due to random chance. Those 1-3 men might well have been traveling in a group of 200 or so, and Europeans may still carry many genes from many of the other men in that group. But because the other members of the group didn't leave behind Y chromosomes, we don't see them in a Y-chromosome analysis.
The study seems to have found good evidence that Europeans are all descended from a small group, but 1-3 men seems to be stretching it.
Shem, I have taken a woman. Inform the men.
I'm asking for some mods to get a handle on this...
Is this post really being modded up to +4 Insightful b/c of a spelling correction?
If so this is complete lunacy...
Also, how do you know I didn't just mispell it...b/c I do that alot too
Thank you Dave Raggett
I'm simply demanding that the sides be accurately represented!
science can't prove or disprove anything that is by definition supernatural
Thank you Dave Raggett
by your definition I have zero beliefs...
0
none...
I don't "assume" anything is true without evidence
BTW: your definition of "believe" is non-standard and guaranteed to cause confusion in ANY conversation about religion, science, or spirituality...
this is why people get into so many pointeless arguments...stupid "personal" definitions of common terms
Thank you Dave Raggett
sigh
I want to say "fuck you asshole" but I wont...
I'll just point out that nowhere did I say that...(see other comments on this thread for a fun definition of 'believe')
I didn't claim that...anyone reading, please understand that it's exactly this kind of crap that causes these discussions to be acrimonous and horribly unhelpful
When we act like GrumpySteen it makes us just as bad as young-earth creationists on the Texas school board
Thank you Dave Raggett
...milkmen. Housewives choice, and all that.
"How fine you look when dressed in rage."
Sample sizes of 8 and 13 respectively? Non-random? .003% per genome.
The mutation rate in humans is only
This is like trying to compare two different atomic bomb explosions given data on only 8 and 13 neutrons from each explosion. They don't even have enough samples to compute the genetic equivalent of temperature (what ever that may be), much less make over arching statements about the two populations. When they have done this analysis for at least 300 random samples from each population I would be interested in hearing the results.
I am not R1b either. I am I2a2b, which is not common. But, when all of the non-R1bs are totaled as a percentage of the European native population, we're a pretty sizable lot. Enough so, that saying "most" of western Europeans are R1b is rather deceptive. As far as the 1-3 fathers, well...yes. Haplogroups generally don't converge, by diverge, so that would mean one male ancestor. But how far back? There are also times when there are near-extinction events which cause the TMRCA (time to most recent common ancestor) to move closer to the present. This has been the case with my I2a2b haplogroup, which is likely the oldest in Ireland, but still has a rather recent TMRCA and small numbers.

... I guess it's safe to say incest is the best when you keep in Europe?
Be seeing you...
Hey I appreciate that you gave a real answer...
I know it doesn't matter but I know that my typing style can be grating, and I have been properly instructed in using the English language in print.
I type this way because I choose to...I do it with intention. You don't have to believe me but I do have a reason....
I'm trying to subvert the typical "point/counterpoint" babble that passes for intelligent conversation these days. People don't communicate...they *react* to words with retorts that are equally pre-determined. It is very much like "newspeak" from the oft-cited '1984'
I make my words a bit grating precisely for that reason. I *want* people to pay attention...I am not making the same point everyone else has made. I **DO** believe we can all agree and move forward and I have had some very interesting conversations this way.
Also, I must note, that if GP was bothered by the fact that I speak with authority making interesting points but do it using text are....welll....
why didn't GP just say that???!?!?
Thank you Dave Raggett
I love how you took the time to *link* to the comment, but you couldn't just quote the specific words from the post...
**because they don't exist**
that post you linked to...I read it when it was first posted and again now from your link
IT DOES NOT SAY WHAT YOU CLAIM
If it does, then just quote it...you already took the time to type out a hyperlink...just blockquote where that comment you linked to claims that the Genesis account is litteral truth
Lets see it
Thank you Dave Raggett
I know what started the thread, it was a guy making a joke about the fact that Y-E nuts would use this to say it proves the Bible true...
I get all that...
That was a joke...that everyone gets...I started a thread talking about mythology and science...
where...the...fuck...did anyone say anything that you're complaining about?
the comment you linked to did not say Genesis was true anywhere...the original GP was a joke...
who said it???
who said Genesis was true, therefore provoking your comment?
Thank you Dave Raggett
Damn, you'd think they'd have gotten tired of sex after the first million or so.
But I guess they deserve some props. To have fathered most Western Europeans, they had to be some serious playa's, you know? I mean, they put NBA stars to shame.
You are welcome on my lawn.
GP seemed to think they were "grating" enough to take the time to correct my spelling of "alot"
and actually you as well have taken the time to type out a response to something you think is "irrelevant"
if my words didn't get noticed, GP would have never corrected my usage of "alot"
Thank you Dave Raggett
I love it how the press reports this result as if the family tree had a single root.
A family tree has two parents, four grandparents eight grandparents, etc. Out of the 2^n ancestors in the n-generation, two branches standout, one the fully male one carrying the Y chromosome and the other the fully maternal line, carrying mitochondrial DNA. There are good mathematical reasons why such lines come to be dominated by a few individuals over the centuries if not millenia yet the press makes it sound like Warren Beatty was alive 100K years ago fathering each and every one of us. As someone else pointed out, if somehow I became Will Chamberlain and happened to father 10K daughters but no male offspring, the Y chromosome line would makes it look like I ws never there though in practice I'd be the (grand) daddy of half of New York within a few generations.
If god favors my group, then the other groups are not favored and are therefore inferior and unworthy of my concern.

I'd be more concerned we're all inbred. So 3 dudes, how many women?

You have two copies of 21K-some genes. At some point an ancestor will make no contribution. (Of course there is a lot more stuff in the genome than the protein-coding DNA.)
Busy dudes.
Not much else to do on cold winter nights except make whoopee.
This is the sort of study that demands peer review.
It is far beyond me to understand the details of this study, and it's claims. But it is absolutely fascinating, if true, even taking the Male-only Y and Female-only Mit inheritance factors into account.
When I see things like
We used coalescent simulations ... The best-fitting models in Africa and Europe are very different. In Africa ... numbers expanded approximately 50-fold. In Europe ... as soon as the major R1b lineage entered Europe ... expanded more than a thousandfold.
then I know enough to know that the assumptions used matter, but also that I don't know enough to evaluate those assumptions.
We're all inbred. Live with it.
Or, choose a definition for a particular level of inbreeding to get concerned about and stop worrying about it.
There is an awful lot of ink spilt, and sometimes blood, over this with respect to human breeding, but livestock breeders have a lot of practice at using controlled inbreeding as a tool to increase the representation of a desired stock animal's genes in future generations, prior to expanding the stock. They tabulate levels of relatedness of interest to them, down to 1 part in 16 (6.25% common alleles). From which I guesstimate that 1 part in 32 relatedness is close enough to random for them to not be of interest for the breeders. So, if you tabulate your family trees back to the 5th generation and find no-more than two great-great-grandparents in common between the two people, it's unlikely to be a problem. If you go back to the next generation and find no more than 4 ggg-grandparents in the family tree, it's also not likely to be a problem. For more complex layouts of consanguinity, you'd have to calculate the summed probabilities yourself - and that's where people have messed up repeatedly in the past.
