Good point. There might be other undiscovered lines descended from R out there. Any statements like this all require the implicit "in light of the current knowledge base".
If there was a lot of R* out there, I would suspect that we would find other SNPs to define R3 or R4 (although I doubt they would be called that for long).
Sinilarly, if there was a lot of R1* out there, I would suspect that this would get divided into R1c*, R1d*, etc.
So far, though, modern descendants of these postulated haplogroups haven't been found. Yet, if you go to ISOGG & look at the number of SNPs that uniquely define P, R & R1, one sees a strong hint that many other branches once existed.

One thing to remember is that NONE of the modern patrilines or matrilines are of Neanderthal origin. All go back to a source in East Africa.
Some might consider this a discrepancy, but it isn't. Most human patrilines & matrilines have been elimintaed by genetic drift. As an example, we can look at the human patrilineal group R. One man had the pertinent SNP mutations perhaps 25,000+ years ago. By the time humanity was coming out of the last Ice Age (12,000+ years ago), Mr. R____ probably had countless descendants scattered across Central Asia. Yet, only THREE of these descendants carried y-DNA that survives to this day: R2, R1a, R1b.
All other lines of patrilineal descent from Mr. R_____ went extinct.
If 99% of all patrilines have gone extinct, one shouldn't be too surprised to learn that the few patrilines that the earlier population had inherited from the Neanderthals were among the 99% that later vanished.
Autosomal DNA has a far greater chance of survival & this is no doubt where we find that 1% to 4% of Neanderthal DNA. It would be interesting for Family Tree DNA to develop a test in conjunction with Family Finder that would show which parts of the 22 autosomal chromosomes are Neanderthal.

When her father doesn't return from searching for the creature, the girl and her boyfriend head out to the desert to find him and the girl is taken hostage along with her father...Its up to the efforts of the boyfriend to rescue the father and daughter before the caveman can make her his mate......It is so bad, its good!
But seriously, I think National Geographics has been running a program this week about the possibilty on intermating between the two..

Duh...
What am I saying, I watched the program the other night and it was very interesting, I think it was on National Georgraphic channel...

Aug 2008 study: Neanderthals probably did NOT interbreed
See http://richarddawkins.net/articleCom...e,page1#227187
and
Scientists who sequenced the mitochondrial DNA of a 38,000-year-old Neanderthal returned no evidence of ancestral interbreeding with our long-lost cousins. That mild disappointment aside, the study, published today in Cell, is an impressive technical achievement. "For the first time, we’ve built a sequence from ancient DNA that is essentially without error," said study co-author Richard […]

Your Pappy
Reports say some men have Neaderthal DNA ,but no modern women have any-so maybe your daddy is a neanderthal.....?

I mentioned earlier on this thread that I went to high school with a Neanderthal teenager. He would be a middle aged Neanderthal by now.
I think he got an A+ in shop class for flint sharpening and for making the perfect spear thrower.

Neanderthalls!
Looks like it should be on the cover of The Sun or World Weekly News!Maria
