Genome of Neandertals Reveals Inbreeding
sciencehabit writes "In a report on the most complete genome of a Neandertal ever sequenced, an international team of researchers has found that the parents of a Neandertal woman from Siberia were as closely related as half-siblings. The genome also shows that at some point the Neandertals interbred with other human groups, including their cousins the Denisovans, and our own modern human ancestors. There are even signs of Denisovans interbreeding with a mysterious archaic species. In all, the study suggests very close encounters among the several kinds of hominins living in the past 125,000 years. The detailed genome of the extinct Neandertals—our closest relatives—also offers a new look at the genetic differences that set our species apart from all the others."
So, they are from Alabama or the Carolinas?
Not a surprise really. There weren't exactly large groups running around to intermingle. You want to procreate and expand the species you had to look within your own local group.
. . . so easy, a caveman could do her!
Incest is best. Keep it in the family. Or genus

You don't say.
You can't handle the truth.
But hey. If it floats your skirt up, go ahead and fantasize.
Every biologist wants to discover a new species - so they grab onto every straw to find one - resulting in many bogus species.
Excuse me, but please get off my Pennisetum Clandestinum, eh!
Have gnu, will travel.
But modern humans are not from ONE SINGLE stock either.
For example, the Denisovans have offsprings, but only part of the modern humans are their offsprings.
And then, while most modern humans have Neandertal genes inside them, some modern humans do not.
Muchas Gracias, Señor Edward Snowden !
People will fuck anything that moves! News after football.
in runs in the family
It's all relative in West Virginia.
Well that certainly explains this animated feature, voiced by the last living Neandertal:

There was a great article in Science a few weeks ago evaluating 6 extremely complete skeletons that were "collected" by a giant cat about a million years ago. (reference below)
The biggest revelation to many biologists was the amount of variation among the skulls. If they'd been found independently, they probably would have been put into different species. It's almost as if biologists haven't figured out that people vary quite a bit within species.
Why can't we just see ourselves as one big amorphous mass of metabolism - still trying to climb out of the primordial ooze?
A Complete Skull from Dmanisi, Georgia, and the Evolutionary Biology of Early Homo, by David Lordkipanidze, Marcia S. Ponce de León, Ann Margvelashvili, Yoel Rak, G. Philip Rightmire, Abesalom Vekua, and Christoph P. E. Zollikofer Science 18 October 2013: 326-331. An early Pleistocene adult skull illuminates the evolution and morphology of the first hominins outside Africa.
Technically in-breading can't occur in clones.
Look at the Chines: Chromosomes just line-up and what is left behind is the same as what you are arriving to.

Humans like to have sex.
FTA, first sentence...
later they also discuss inTERbreeding among other imaginary species that these guys invent to get more funding
these are modern humans...eventually this stuff will be disproven if anyone takes the time to really check out what's going on
this reminds me of Clovis Culture...it denied any trans oceanic contact beyond a Bering Straight migration that could have only happend once...all from some rock paintings and evidence of axe sharpening
BAM!
Clovis Culture took a giant shit on anthropology in the Americas for almost a Century...now polyneisian potatoes in Chile, Inuits recorded in Europe in 1000 AD, the whole Lief Ericson thing, and genetics of the Incas vs Africans shows that the Americas was progressively settled as long as humans have reached it
Science can be just as closed minded and dogmatic as religion on this stuff
Thank you Dave Raggett
Just because they're trendy to talk about, you don't need to use some new-age, look at me, I know about Neanderthals and Denisovans way of spelling their name. They're Neanderthals, despite the fact that 'tal' is the German word that it's based on.
I want to delete my account but Slashdot doesn't allow it.

So pretty much like the European royal families, huh?

Ma? You awake?
Sweet FA sets us apart from all the others. We're just the latest and most successful members of the genus homo.
I read that inbreeding was bad and causes issues like defects.
Ant(Dude) @ Quality Foraged Links (AQFL.net) & The Ant Farm (antfarm.ma.cx / antfarm.home.dhs.org).
Any small tribe or village, even up to the last century, is going to have some inbreeding; if there's only 250 people in your village (and assuming that the population has been relatively stable for the last few hundred years) and every potential mate in your village is at least a 4th cousin, probably more than one way. As James Burke noted, the steam engine caused a revolution in genetic engineering, because with the railroad and the steamship, it was possible to meet and mate with people who weren't related to you at all.
Hybrid vigor works on people. Look at the stature of people from feudal Japan and China; stereotypically small, almost tiny. When those people came to Hawaii and wed other Japanese (and Chinese) people from other villages, their children were inches taller - living in the same culture, often on similar diets. Their children were taller still, and THEIR children are the size of everybody else.
The summary clearly states inTERbreeding, the title turned it into inbreeding which is more or less the opposite. But this is Slashdot where the editors can't write and the posters can't read.
Does stature have survival value? Seems very unlikely to me.

except that TFA includes the quoted title from the summary...

Hmmm who can't read?
Source article:
"Paabo and his colleagues could tell that this Siberian Neandertal was the product of inbreeding and that her ancestors also chose their mates from their extended family. This suggests that this Neandertal woman came from a small, isolated population, the team reports online today in Nature."
Abstract Here: http://www.nature.com/nature/journal/vaop/ncurrent/full/nature12886.html
" mating among close relatives was common among her recent ancestors"
Yes, the article also discusses interbreeding.
family tree discovered! good job! Q: What's the definition of incest? A: Sibling revelry!
Not really any such thing as an "Indian"
Then explain Inde, the Apache people's name for themselves before U.S. westward expansion.
Depends on the environment. But it doesn't need to have survival value, it just needs to improve reproductive success over several generations (its no good having lots of children if it results in fewer grandchildren). Look at the male Peacock's tail, in itself it is clearly detrimental to survival, but a big colourful tail works as an indicator of greater fitness to the females.
And what arose form this inbreeding?
Modern Man.
"If any question why we died, Tell them because our fathers lied."
While it may beOK to identify different human populations; this news does great disservice to the fact these all the SAME species. Next we'll be identifying the moderns populations of humans residing in sub-Sahara Africa as less than human.
... stays in Neander Valley.
There is only ONE intelligent ape species on this planet- us. But we know, as an absolute fact, that once there were many. What happened? Organised religion.
Before the age of writing (recorded history), Man (us) developed 'organised religion', and organised religion had only ONE real goal- to exterminate every other intelligent ape species on the planet.
Human spirituality is the most beautiful aspect of Man, and organised religion the most vile and evil perversion of our inherent spirituality. Given that every individual can find spiritual purpose for themselves in their own lives, WHAT, exactly, do you think the purpose of organised religion is meant to be?
Organised religion seeks to define "THE OTHER", and inherently define 'the other' a fundamental 'evil' or a fundamental 'lesser'. Put simply, 'the other' is to be exterminated or enslaved. Judaism, for example, spent most of the last one thousand years plus defining the dark-skinned Humans of Africa as 'the other', and actively generated as many mechanisms as possible, first in partnership of the pre-Muslim peoples, then in partnership with the Muslims, then in partnership with the Modern Christians of Europe and the Americas, to enslave these people. Organised religions, by definition, define their members as the "MASTER RACE" or "THE CHOSEN PEOPLE" (same thing), and need to emphasis this fact by identifying "sub-Humans", and treating these people as badly as possible.
Man's first organised religions had it 'easy'. The 'others' were the other intelligent ape species, easily identified by appearance, and different inherent patterns of behaviour. Just as Judaic (Judaism and Modern Christianity are Judaic religions- original Christianity was not) America criminalised sex and marriage between 'white' and 'black' Humans across most of America's history, our ancestors living in far less developed societies (pre-writing) were infinitely more vulnerable to the racist messages of the leaders of the first organised religions.
We wiped out the 'competition', although to ordinary Humans, our genetic cousins were NEVER competition. Not all of this extermination was done with blatant mass murder, although much went this way. Just as much extermination happened using the British Empire methods of 'reservations' and forced 'migration' where 'the other' could be indirectly starved, or herded together to suffer the maximum effects of disease, and massive increases in the rates of infant mortality.
Again, put simply, the leaders of early organised religions did whatever their local flock would tolerate. Direct mass murder where possible. Indirect mass murder (as seen in more recent times with the culling of the local population in parts of Africa, the Americas, and the South Asian islands down through Australia) where the flock proved to be more 'sensitive'.
Today, organised religion (especially the Judaic trio of Islam, Judaism and Modern Christianity) is more aggressive and more murderous than at any previous time. 'Freedom of Conscience' has not lessened the grip of organised religion, but through "trial by fire" forced organised religion to become vastly more, well 'organised' and educated in the means of effective population control.
Today, the most powerful organised religious leaders agree with Bill Gates and Tony Blair that at least THREE BILLION of us are "surplus to requirements". Blair is happy to point to the genocide of other intelligent ape species to justify his claim that "sometimes god's will means doing the 'unthinkable' ".
When those people came to Hawaii and wed other Japanese (and Chinese) people from other villages, their children were inches taller - living in the same culture, often on similar diets. Their children were taller still, and THEIR children are the size of everybody else.
Similar, but almost certainly not the same diet their parents had growing up. Heights is up across the Western world across population due to increases in available calories. The Dustbowl and the Great Depression were the last times in America that large swathes of the population suffered famine. Despite all the unhealthy effects of too many calories in the American diet, we generally have far more access to protein and to vitamins & minerals than our ancestors from about a century ago and than people in most of China even today.
Ironically though, too much nutrition (i.e. obesity) in childhood can retard the adolescent growth spurt. This is part of why America is no longer the tallest nation.

So I did a real bad thing there because...
...l think you're my sister.
Is that all? No.
My family's last name is Buckwalter.
My brother's name is Cletus.
So you see, we're not related.
We can have sex again.
Joe, what's the matter?
Don't I turn you on?
I don't know what the problem is.
Would it help if you went back to thinking I'm your sister?
Like I'm some sort of white-trash perv?!
I'm your sister. I'm your sister.
Oh, you're my sister!
Many scientists classify modern humans and Neanderthals as both the same species, they're both human e.g., Homo sapiens. They are then classified as different sub-species. Sub-species can interbreed.
It is also spelled Neanderthal, with an 'h'.
I know, picky, picky, picky...
