Denisovan Genome Fully Sequenced.

Archaeologists and paleoanthropologists discovered a tooth and a finger bone in the Denisova cave in the Altai Mountains a few years ago.  They extracted DNA from these, and made the discovery that this was another archaic form of human that was previously unknown, and also very closely related to us, and also to Neandertals.

Further studies have confirmed that they also mated with modern humans, as well as Neandertals.  

 

Now, the full genome has been sequenced.

 

It is quite amazing that the science of genetics is rewriting the history of our big, human family, and fills in the gaps where the archaeological record cannot tell the story, nor morphology and comparative anatomy.

The technology to extract DNA 41,000 years old is amazing.

The discovery of another advanced human is profound.

And they dont get a whole dna strand. DNA tends to quickly break apart. There best hope is to find stands long enough to contain useful enough info so that they can figure out where it goes in the complete strand. So they get a huge jigsaw puzzle, with different people working to describe the individual pieces just so you can put them together.

basically putting back together war and peace from 1000 different mostly destroyed copies and all in individual pages thrown everywhere out of order.

This is just as huge as the mtDNA sequencing of Neanderthalis. The question is were they able to sequence the mtNDA also? Would that be more useful for tracking driect lineage?

I gotta ask. . . curiosity is strong. . . all ethical arguments/considerations aside. . .

Is is possible to clone this person using this DNA? Would it not be cool to see what this person looks like via cloning?

(I'm not interesting in a debate about this. Just wondering. . . .)

Daniel, what a brilliant idea! One can never have enough pets! My humble household has two dogs. Maybe my two dogs and the cloned thingy can chase each other outside. I can then watch and laugh and enjoy the playfulness.

What would YOU do with your pet clone?!?!

HA!

It truly saddens me to say this . . . but. . . an ameba seems more evolved than any of the ding-dongs running as a Republican Presidential Candidate.

Now. . . back to our pet clone. . .

Can we clone...and what would we do if they ended up being superior in intelligence and body?

BTW, the are current efforts to clone Mammoths found in the Siberian PermaFrost.

Interesting. . . didn't know that there are efforts to clone those Mammoths.

Regarding cloning whatever/whoever was found at that cave. . . honestly, it's just pure curiosity on my part to see what they looked like, how they acted, etc. Without getting into a debate about cloning (which I just don't feel like doing at this time), I'm pretty happy being left curious. I don't want to be lunch-meat for any superior being. LOL!

My two dogs will miss their play-mate, though. They love romping in the woods. LOL!

Except. . . they just MIGHT get that play-mate after all! If the scientists are successful in cloning a mammoth, then my happy dogs can folic about with Dumbo, the Really Hairy Elephant-looking thing. I just have to be concerned about my two fidos being crushed to death. That wouldn't be a good.

Cheers. . . :-)

Edited to add. . . I will say this about cloning. . . Obviously the technology is there. Cows and sheep and maybe even a mammoth have been cloned. It's not a far stretch to clone humans if it hasn't been done already. I wonder if it has?? Given the over-population of the world today, I'm not really sure that I want to see human's cloned (even ancient humans). (Oh dang! There's an open for a debate.)

I have little doubt that human cloning has occurred. Maybe not in the U.S. (although I really don't put American scientist in a higher ethical plane).

I would guess that some sort of human cloning has occurred in South Korea as that country is in the forefront of genetic engineering, using human stem cells. I do not believe (without any basis) that a cloned human is walking around.

Michael -

Just thinking out loud. . . .

Human "cloning" is already being done quite naturally. It's probably been going on for thousands and thousands of years! These "clones" are called identical twins (or identical triplets, quadruplets, etc)! LOL!

Well, it's time to go. Gotta stop cloning around!

HA!

Hope to see you, again, on the 'Vine at some point in time. In the meanwhile, be well. :)

Cheers. . . :)

Daniel A. Hallo

I’d just like to see them, maybe get a few pairs and let them start a colony somewhere, it’s probable our fault they are extinct in the first place.. I bet they are more advanced then we give them credit for, maybe even a less violent species then we are.

We just have to remember to ask ourselves how advanced and cultured we would be if we were born with nothing but sticks, rocks, and an oral tradition of the same. Our world around us is what prevents us from being grunting savages.

We have toddlers now attempting to interact with magazines by sliding their finger across it because they are more used to touchpads than pages. Our species adapts quickly. Any Neanderthal or Denisovan humans would do the same.

What I want to know is, where is Briwnys? She was right all along, and this is exactly what she predicted years ago.

Daniel -

Knowing that great advances have been made in cloning, my curiosity is certainly peaked about "making" some long-extinct humanoid come alive. Honestly, there is a significant part of me that says, "Go ahead! Do your technological magic and clone those thingyies!"

But. . . (and this is a significant "but" which is not to be confused with my significant butt that I sit on) I am painfully aware that there is soooooo much more that needs our intellectual attention. Gosh, I just got done sharing a long post about contraception, healthcare and religion. Cloning a long-forgotten humanoid just seems too surreal to me (and I LOVE surrealism!!!) when I believe that we need to spend our collective finances and intellectual energy on things like finding a cure for HIV and Hepatitis C, or even finding alternative and effective forms of energy other than oil and coal (something which should have been thoroughly developed decades ago!).

(Gosh. . . I did say that I did not want to get into a debate about cloning, didn't I!! LOL!)

But truth be told, that curiosity factor is there for me! If we had a perfect world where everyone respected each other and we could confidently (and affordably) drive our cars using electricity or guarantee clean, safe drinking water for every individual on this planet, then maybe, just maybe, I would say "Clone the sucker!" LOL! We don't seem to be there, yet, though.

It's been good chatting away with you on this subject, Daniel. I hope to trade more thoughts with you on the 'Vine in the not too distant future. Take care. . . and be well. :)

MarkD - 555 !!!

I have a question to ask you. You wrote:

Who is "Briwnys"??? What did she say years ago?!?!?

It's good to see you on the 'Vine, Mr. MarkD-555. :)

Who is "Briwnys"??? What did she say years ago?!?!?

She's been saying for years before this that we had another "human cousin" we interbred with from Asia, well before even the conclusive proof we bred with Neanderthalis. She always has insightful scientific knowledge or poetry to share.

Anticipating this finding in 2008, before conclusive Neanderthal interbreeding evidence, before even finding this bone of Denisovan "X woman":

http://blessed-isles.newsvine.com/_news/2008/08/19/1760269-myths-of-19th-century-science-darwinian-evolution

It's a complex article though.

Thanks for sharing the link, Mr. MarkD-555! Just started reading the article. Also started to read the discussion that followed! Very, very cool!!!

This is the first that I heard or seen of "Briwnys". Seems that she is (or was) a member here. I'm going back to the article and discussion for more reading. (Got some spare time on my hands.)

By the way. . . I've always held a belief that there was whole lot of "interbreeding" amongst the humanoid species. We're a horny bunch! LOL! (Wouldn't be surprised of there's a sheep-man running around somewhere. But that's a whole 'nother topic for another time for another thread!! LOL!)

Take care, Mr. MarkD-555! :)

it’s probable our fault they are extinct in the first place.

Partly. Humans certainly predated the Mammoths, but remember, they are called Wooly Mammoths for a reason: they lived right along the edge of the ice from the then current ice age.

As the ice retreated, many of the large animals of the time could not evolved or move quick enough to keep up with the climate change.

    "Speculation" - yep, you are 100% correct. Good for you!

      Ah, Denisovans, Neanderthals, mitochondrial DNA, nuclear DNA, cloning, genetics and paleoanthropology: the scientific study of our origins has come a long way!

      I do not think that, with our current sequencing technology, that we could clone either a Neanderthal nor a Denisovan. As one commentator suggested, DNA breaks down rather rapidly after death. What we are looking at are reconstructed "signatures" of nucleotide sequences.

      Mitochondrial DNA is more easily sequenced, and usually preserves better, than nuclear DNA. The problem is, mitochondrial DNA does not code for the same things, nor even similar things, that nuclear DNA is responsible for. Mitochondria are also further not passed down from the male line, but only from mother to daughter, that is, the maternal line. So, mitochondrial DNA only gives part of the picture.

      If you recall the sequencing of Neanderthal mitochondrial DNA a few years before, the interpretation about how related Neanderthals were to us was completely different than the nuclear DNA findings!

      Mitochondrial DNA analysis tells only part of the picture, and additionally, the rate of mutation is still only an estimated rate. So, when geneticists extrapolate back into time about "when did we diverge", this is an estimate of the "Molecular Clock", and this hasn't been demonstrated quantitatively nor qualitatively, to the best of my knowledge.
