Interesting, I would love to see more information on this -- I had not heard this previously.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by jbeales on Thursday March 15, 2018 @09:54AM (#16592832)
It makes fairly logical sense. Neanderthals were fairly well-installed in Europe when modern humans appeared in Africa. As modern humans would have expanded northward into Europe, done their thing with the Neanderthals, (some breeding, lots of killing), and continued eastward, so the human population still in Africa would probably have no Neanderthal DNA, but the population in Asia would carry the results of some interbreeding with Neanderthals.

The question this brings up is how different are Neanderthals from Homo sapiens? I was taught that the definition of a species is that two individuals could reproduce and have fertile offspring. It seems there are exceptions to this rule, (as Neanderthals and Homo sapiens are different species).

Re:Ancient DNA Is Rewriting Human and Neanderthal History by noelwelsh on Thursday March 15, 2018 @11:20AM (#16593590)
I don't think the concept of a species is well defined. Tiger and lions can interbreed, as can donkeys and horses. And then there are ring species. Biology does whatever it does and then humans try to fit words around it.

Edit: correct mules to horses

Re:Ancient DNA Is Rewriting Human and Neanderthal History by mhluongo on Thursday March 15, 2018 @11:25AM (#16593634)
You're thinking donkeys and horses. I believe a mule is the sterile result of that interbreeding.
Re:Ancient DNA Is Rewriting Human and Neanderthal History by sampo on Thursday March 15, 2018 @02:09PM (#16595175)
Mules are mostly sterile, but not 100%. Wikipedia reports some cases where female mules have produced offspring.
Re:Ancient DNA Is Rewriting Human and Neanderthal History by tabtab on Thursday March 15, 2018 @06:39PM (#16597081)
Interbreeding can be ranked on a scale. The less related the groups are, the more problems there are with reproducing. Perhaps a hard boundary of "species" can be drawn where the probability of successful offspring approaches zero. However, that's difficult to measure in practice.
Re:Ancient DNA Is Rewriting Human and Neanderthal History by cimmanom on Thursday March 15, 2018 @12:28PM (#16594241)
My understanding is that Neanderthals are now classified as a sub-species rather than a distinct species. So instead of Homo Sapiens and Homo Neanderthalensis (sp?) we have Homo Sapiens Sapiens and Homo Sapiens Neanderthalensis.

It's not entirely unlike dogs and wolves, which can interbreed fluently. There are dozens of subspecies of Canis Lupus (red wolves, gray wolves, etc, etc), and one of them is Canis Lupus Familiaris, the domestic dog.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by patall on Thursday March 15, 2018 @05:01PM (#16596495)
The current de facto status is that the concept of species does not exist anymore, or more precisely, it mostly only still exists for historical reasons and coherence with it. When talking about genetic identity nowadays there is only the (type) specimen and genetic distance to other individuals. For example, Svante Pääbo and his team set precedence on purpose in not declaring the Denisovans anything but only describing a group of humans that genetically differ to an unexpected degree from modern humans.
Re:Ancient DNA Is Rewriting Human and Neanderthal History by ChemicalWarfare on Thursday March 15, 2018 @07:27PM (#16597398)
how far of a distance before the line is drawn? by that logic chimps are also " a group of humans that genetically differ to an unexpected degree from modern humans."
Re:Ancient DNA Is Rewriting Human and Neanderthal History by skadamou on Thursday March 15, 2018 @04:31PM (#16596275)
There are actually three ways to define a species. The morphological species concept, the biological species concept, and the phylogenetic species concept. Species that can interbreed satisfy the biological species concept but there seems to be more consensus among biologists that constructing a phylogeny is the better way to define species.

This somewhat problematic however because there is rarely enough data about a species to create a complete phylogeny of a species and its common ancestors. Additionally, it is thought that this concept would lead to the naming of many more species than we presently recognize. If you’re interested in this kind of thing I would encourage you to check out the link below!

I don't think that explanation works. In your scenario, you wouldn't expect humans in Asia to have more Neanderthal DNA than humans in Europe.
Re:Ancient DNA Is Rewriting Human and Neanderthal History by jccooper on Thursday March 15, 2018 @03:05PM (#16595636)
As the article notes, there seem to have been several significant post-Ice Age re-populations in Europe, of which one or more of the incoming populations may have had little contact with Neanderthals. "Mixed" populations to the east could have survived more intact.

I have not heard that either. According to 23andMe, I'm in the 99th percentile for Neanderthal DNA variants and my ancestry report claims I'm a disappointingly un-diverse 99.9% European.
Re:Ancient DNA Is Rewriting Human and Neanderthal History by mc32 on Thursday March 15, 2018 @10:16AM (#16593007)
I don't think I'd ever hear a non white say they are disappointed with being 100% what they are, be they Asian, Black, etc. Maybe there are, I've never home across them, but a few whites have this tendency to wish for having "interesting" ancestry like sen. Warren.

It's something odd. As if they are somewhat uncomfortable on their own skin. Shame is the wrong word, but i can't find the right descriptor. On the other hand, i think this points to social pressures that make people feel that way about themselves.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by delecti on Thursday March 15, 2018 @04:06PM (#16596129)
I agree it's odd, and yet still shared that sense of disappointment in the lack of surprises in my 23andMe report. I also don't think it's entirely irrational.

The most interesting result is the least expected result that doesn't include bad news. Outside relatively small circles, the vast majority of white people will lose none of their privilege or social position if they find out their ancestry includes something unexpected. It's clearly pretty widespread too, because all of the 23andMe advertising includes people ostensibly of European descent who find out they've got unexpected ancestry.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by kolinko on Friday March 16, 2018 @04:26AM (#16599337)
Perhaps it's a matter of where you come from?

In US, varied ancestry is a norm if I'm not mistaken, so having a "pure" heritage makes you unique. In many countries it's the opposite - the default is "pure" heritage, and having varied background is what makes you stand out.

Also, from the health perspective, varied ancestry is better if I'm not mistaken. Kind of like pure breed animals being less healthy in general, compared to mixtures.

I'm 99.5% European (86% Eastern European), and 0.5% East Asian/Native American. I hoped for more varied ancestry when I received the results.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by ChemicalWarfare on Thursday March 15, 2018 @07:34PM (#16597433)
in some circles it is considered "cool" to be admixed or foreign. there's also a fair amount of virtue signaling attached to that as well.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by smhost on Thursday March 15, 2018 @01:35PM (#16594865)
How can you not understand black pride? The story of the Negro that survived the racist horrors of white oppression, the voice of the enslaved person that became La Marseillaise sung at the Haitian revolution, that became jazz, that became hip hop. The impossible resistance against the whitewashing and cultral genocide, the freedom and liberty earned by wielding the spirit of the Enlightenment channeled through the black experience. Black identity is more American than America. Freedom from taxation against the freedom to exist. There is no comparison. It's worthy of pride.

There's dignity in guilt, and it's essential for growth. You really don't seem to understand the human condition.

I don't think he is. Let me try to explain why.

I haven't done a DNA ancestry test yet, but I imagine I would be pretty happy to learn that there were several peoples/races?/cultures behind me, beyond my apparent South Asian heritage. This does not imply that I am ashamed of my origins - quite the contrary, in fact - but that I imagine it would be nice to ... be more, a citizen of the world, in a fashion.

I would expect this outlook of anyone with a cosmopolitan upbringing by default, as well as anyone who has exposed himself or herself to other cultures via media (books, movies, etc..).

We've gotten to a point where Europeans seem to be looking for anything to give them some minority culture status.

Just take pride in who and what you are and where you came from.

> Just take pride in [...] where you came from.

I think one problem is that everyone has a different definition of the word 'pride'. Over here in Europe a lot of people think of pride as something you feels when you actively achieve something.

Ran a marathon? You can be proud of this!

You were born white/black/asian/... in France/Turkey/Spain? There is not much to be proud of, at the end of the day it's just pure luck who your parents are and in which culture you are born.

Schopenhauer said it best:

"The cheapest sort of pride is national pride; for if a man is proud of his own nation, it argues that he has no qualities of his own of which he can be proud; otherwise he would not have recourse to those which he shares with so many millions of his fellowmen.

The man who is endowed with important personal qualities will be only too ready to see clearly in what respects his own nation falls short, since their failings will be constantly before his eyes.

But every miserable fool who has nothing at all of which he can be proud adopts, as a last resource, pride in the nation to which he belongs; he is ready and glad to defend all its faults and follies tooth and nail, thus reimbursing himself for his own inferiority."

It's pretty much frowned upon to be in any way proud to be a pale skinned European; mainstream media demands we feel shame for all the oppression we did in the centuries before our birth.

That said, I don't understand how I've can be "proud" of which country you were born in, makes no sense to me.

>I don't understand how I've can be "proud" of which country you were born in, makes no sense to me.

I guess it all depends where you draw the line, do you feel proud of your parents? Some people will say "No, I only feel proud about what I accomplished myself." And that's ok, that's his point of view, we could say this is a subjective matter, from my point of view, I feel proud of who I'm, I'm proud of my parents, and then I can extend that line and say I'm proud of my community, my city, my country, my civilization, I'm proud of being part of humanity, obviously that "proudness" will increase when that line is nearer to me, in other words the more relatable to myself the prouder I can be.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by fein on Thursday March 15, 2018 @10:38AM (#16593206)
You use 'we' to describe your collective, showing you understand the concept of heritage, and then go on and say you don't understand pride in your people.

Only whites seem to have this internal conflict, and that makes far less sense than being proud of the society your people created.

I was born in Canada and I'm definitely proud of it. Not necessarily that I was born here, but that Canada is the way it is and how it has shaped me. I think that is what pride in a nation really is. Americans who are proud to be Americans are this way because they perceive it to be the most free country in the world, and to be a part of that heritage lends something to pride.
Re:Ancient DNA Is Rewriting Human and Neanderthal History by emmelaich on Thursday March 15, 2018 @11:39AM (#16593753)
Take pride but don't take it too far. I have Irish ancestry among others but find St Patrick's day a little ridiculous.

Also, to echo another commenter here, take the classic quote from Samuel Johnson: "patriotism is the last refuge of a scoundrel"

Also pride is considered to be the worst of the seven deadly sins for good reason. So tempting yet can be so poisonous.

Pride can be good and bad. Being proud to succeed as a single parent, or proud of being the first to graduate university in the family.

Proud to be black or proud to be white.... Getting iffy depending on context. Of course, the opposite would be troublesome, ashamed to be black, or ashamed to be white.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by creep on Thursday March 15, 2018 @02:14PM (#16595229)
Pride in heritage is still important. Genes don't necessarily define a person's success (genes are regulated in expression, and so expression can be changed by environmental factors) but they do anchor an individual to history. They ground a person in eons of time. Being proud to be black or white or anything else is part of that.
Re:Ancient DNA Is Rewriting Human and Neanderthal History by mc32 on Thursday March 15, 2018 @11:50PM (#16598481)
I think there is a difference in denial --which I don't propose and overtly and outright saying I'm proud to be "...". Be comfortable with being "..." accept being "..." and not wishing to be anything else.

I hope people feel their heritage is "cool" but I'd rather not have people feel their heritage or a different heritage is "better".

On the other hand, I feel that there are some societies that indeed contributed more to civilization than others. I don't think that's deniable. But I mean as a person one should not feel "better" or "worse" than any other person because of heritage.

Re:Ancient DNA Is Rewriting Human and Neanderthal History by creep on Friday March 16, 2018 @01:47PM (#16602484)
I don't think we can say which societies contribute more or less. That's based on the metric of what they are contributing, but overall that discussion is too complex to definitively say who contributes more.

As for feeling "better" I agree with you, only that pride is not necessarily a feeling of superiority. In most cases it is an acknowledgement of something related to the individual that he or she feels is inherently good. Not everyone associates good with better.

I haven't taken a DNA test but I would be very excited to learn I am 99% European. My family doesn't have a lot of historic records as to our origins. We know we technically started in Russia (on my mother's side), and my father is pure Italian, but other than that we don't know jack shit. If my genetic line came from just one region, I would have hope for piecing together my family's ancestry. As it stands, I feel disconnected from my roots.

To find out (through a 23andMe report showing 99.9% Euro genes) it wasn't true was unsettling, like I'm not really who I thought I was and also have much less of a connection to the area. Also disappointed because it means someone in my family lied to all of us about where they came from.
