Do you have Neanderthal Ancestry? What would you think if you found out you did?

Asked by MadMadMax (3397points) November 13th, 2013

Neanderthals were a group of humans who lived in Europe and Western Asia. They are the closest evolutionary relatives of modern humans, but they went extinct about 30,000 years ago.

The first Neanderthals arrived in Europe as early as 600,000 to 350,000 years ago. Neanderthals — Homo neanderthalensis — and modern humans — Homo sapiens — lived along side each other for thousands of years. Genetic evidence shows they interbred and although Neanderthals disappeared about 30,000 years ago, traces of their DNA — between 1 percent and 4 percent — are found in all modern humans outside of Africa.

Apart from the curiosity of finding what percentage of a modern human’s genome is Neanderthal, the information has great value for science. By comparing our DNA with Neanderthal DNA, scientists can detect the most recent evolutionary changes as we developed into fully modern humans.

Some of us have no Neanderthal DNA, others have up 4%. Would you be surprised to find out you’re part Neanderthal and what you suspect that means?

I was going to say “that explains the existance of conservatives”, but that would be insulting.
To Neanderthals.

Yeah! 3.1% of my DNA is from Neanderthals and I’m about as open-minded as you get..

No, I wouldn’t be at all surprised. That was relatively recently, however. Long before that I think my ancestors were most likely blue-green algae.

” Would you be surprised to find out you’re part Neanderthal and what you suspect that means? ”

It means we are both of the genus Homo.

I am not sure of what it means as I could have Neanderthal genes that code for a common enzyme that all great apes have, or I could have something unique.

I have that Science article on the neanderthal sequencing. I will refresh my memory and try to get back to this question.

Last I heard there was some speculation that Neanderthal may have interbred with northern Europeans, and the most likely living descendents of Neanderthal are Scandinavian.

Which would mean that Vikings were part Neanderthal.

And someone seriously needs to make that movie.

Using SNPs, small nucleotide polymorphisms, the gene flow of Neanderthal genes into Eurasian human populations show that Neanderthals share more of their SNPs with Asian and European populations than African populations. Neanderthals are more closely related to non-Africans than Africans on average, so the out-of-Africa theory needs some revision.

GIven my celtic heritage, and lord knows what from my mom’s side, it wouldn’t surprise me in the least. Might explain my alcoholism!

I hate these kinds of questions though, because once you find out, there’s not much one can do. Can’t delete 4% of your DNA!

Interestingly enough, and among other genetic differences, there are differences in the genes in Neanderthals and modern humans that are implicated in autism, Down’s syndrome and schizophrenia.

Plenty of hypothesis suggesting Neanderthal and Cro Magnon interbred happily.

@Coloma But that Neanderthal strength though…

I wouldn’t be surprised and it wouldn’t bother me in the slightest.

@Seek_Kolinahr & @Coloma I see we’re on the same page with Ayla and the vikings, that WOULD be a bada$$ movie!

I think they were redheads. Most readheads have Neanderthal ancestry.

“Neanderthals are more closely related to non-Africans than Africans on average, so the out-of-Africa theory needs some revision.”

I’m not sure that is the case. It’s more complicated.

They may not have been stupid, their brains were actually larger than ours.

Quite the case. The out of Africa theory states all human ancestry of today is African in origin. Obviously not. I said revision, not refutation.

Most evidence suggests the Neanderthals had bigger brains than Homo Sapiens, tended toward larger social groups, and were much less warlike. There is good reason to think the Neanderthals got wiped out by their less intelligent but meaner and deadlier Homo Sapien neighbors. The winner in the survival of the fittest is the one most willing to kill the competition, not necessarily more fit for anything else.

@dabbler That’s what I’ve read, I’m pretty sure I’m some % Neanderthal. History is usually written by the victors. I’d bet our perception of them is off ~180 degrees.

Jonesn4burgers's avatar

I think I should get tested. I think I tend more towards 11% or even more!
I wouldn’t be troubled in the least to discover any one thing about my ancestry. I am who I am. What I was born with I can’t change, and whatever I could change I have or am still. I’m happy about myself.
@KNOWITALL, @Coloma, @Seek_Kolinahr, movie maybe, but if I were going to go interspecies myself, I’d be looking for Warf (sp?) from Trek NG. He’s a biter too.

Jonesn4burgers: There is only a maximum of 4% Neanderthal in the human gnome. I’m 3.1 so I’m high. I can buy a t-shirt acclaiming my Neanderthal heritage. I think that’s a hoot!

Sadly thats based on a lot supposition and not fact. Just recently we thought they could not speak and now have discovered they not only had language but very likely music.

There is a great deal to learn about them and a more passive people would logically have less chance of surviving in comparison with a more agressive human line.

Jonesn4burgers's avatar

Was just joking about the 11%, still though it would neither suprise nor bother me to have it be true. Neanderthals rock. @MadMadMax, how did you come to be tested?

Constantly updated reports as they discover more. You may carry a gene for a problem but it’s not active – then again it may be active.

Apparently at some point in history Jessie James and I had the same ancestor – probably on my mother’s side.

Tons of stuff you can bring to doctor – warnings regarding high probability of health issues.

I didn’t pay for it. It was a gift to my husband and I from our son who had done it for his wife, brother and himself.
