Scientists are talking for the first time about the old idea of resurrecting extinct species as if this staple of science fiction is a realistic possibility, saying that a living mammoth could perhaps be regenerated for as little as $10 million.
If the genome of an extinct species can be reconstructed, biologists can work out the exact DNA differences with the genome of its nearest living relative. There are talks on how to modify the DNA in an elephant's egg so that after each round of changes it would progressively resemble the DNA in a mammoth egg. The final-stage egg could then be brought to term in an elephant mother, and mammoths might once again roam the Siberian steppes.
The same would be technically possible with Neanderthals, whose full genome is expected to be recovered shortly, but there would be several ethical issues in modifying modern human DNA to that of another human species.
There is no present way to synthesize a genome-size chunk of mammoth DNA, let alone to develop it into a whole animal. But Dr. Schuster said a shortcut would be to modify the genome of an elephant's cell at the 400,000 or more sites necessary to make it resemble a mammoth's genome. The cell could be converted into an embryo and brought to term by an elephant, a project he estimated would cost some $10 million. "This is something that could work, though it will be tedious and expensive," he said.
Okay, I agree that it is an accomplishment for us to be at the point where we can do this. But I believe inthe motto:
Just because you can do something, doesn't mean that you should.
Really, what would be the purpose of this?
And Neanderthals? Don't even get me started!
It went extinct because 1. it was too hot, and 2. we ate a lot of them.
It was mostly the latter.
I'd personally like to see them brought back. Or maybe even just 2.
Let them cope on their own.
C,mon now! You mean you wouldnt want your own cute cuddly baby mammoth to raise. Doing neat things like taking him for his first walk and teaching him to fetch the paper in the morning? You might want to subscribe to 8 or 10 newspaper though.
ok maybe not mammoths but
personally I'd like to try the old Gros Michel bananas that were supposed to be tastier than todays cavendish.
ok since they dont produce seeds might be harder,..but with agro bacteria i bet they can get the right genes to splice.
nearing:
We already know all about these animals
Well, no, actually, there's a lot you can't tell from examining the fossils (or even in the case of mammoths, their permafrosted remains). Their metabolism and enzymatic processes. Their reproductive cycle. Their social organization. Just because they're related to elephants does not mean that their biology and societies are the same.
What about their position in the ecology? I recall reading somewhere that elephant's weight and foot-shape has something to do with keeping down various weeds and pests because they flatten 'em. How did the sub-arctic ecology change after they were (apparently) hunted into extinction?
These are relatively recent extinctions, contemporaries to homo-sapiens, not at all like dinosaurs. One can look at it as playing Dr. Frankenstein; alternatively, might it be viewed as trying to repair the ecological networks that humanity is responsible for eliminating? What role did the carrier pigeon play? The dodo? etc. As much as the snail darter or spotted owl?
We could get this island see, somewhere off of Costa Rica and and fill it with dinosaurs and extinct species...
They probably had their own beneficial imprint just like the buffalo and the great Plains. They were also inhabitants of a much greater area than Alaska and the north. Consider how there has been talk at times of trying to restore some of the plains with its tall grasses and buffalo. Our farming industry is using up that fertile topsoil that the buffs created over many millenia at an alarming rate. You talk about running out of oil, well that rich soil only goes so far down and then it will be gone too with overuse.
mmmmm, mammoth steak
geez, and I thought Kobe beef was expensive.
(cue music - six million dollar man theme) wooly mamoth running across the plain in slow motion
"We can make him better, faster, stronger.....with onions and bar-b-que sauce..."
better, faster, stonger and tastier
I personally volunteer to raise any Neanderthal child created by anyone anywhere. I'll devote 20 years, all love, affection, invention, and anything else a Neanderthal child might need that I can possibly provide.
I mean ... can you imagine - a real non-human intelligence sharing the planet with us again?
Sure it's ethically tough to deal with creating a baby with extinct genes but really ... what is more unethical? Our having driven our Neanderthal cousins extinct? Or our refusing to revive them again when we have that ability?
Let me put it another way. Let's say someone, somewhere, creates a race of Neanderthals. And it turns out they didn't go extinct because of us. It was just bad luck. They turn out brighter, stronger, wiser, longer-lived and generally better. Meanwhile we hit peak-everything and die off. After a couple hundred years the Neanderthals figure out how they could possibly bring us back through their own genetic sciences.
Do you think they should?
"I never saw a miracle of science that didn't turn from a blessing to a curse." - Sting.
So nature is a commodity where living creatures, animals and humans can be resurrected ... for a price. Things are no longer extinct because their time is up but because no one could pay the fee. This is so contrary to life. Nature no longer selects, the dollar does.
Sting has indeed given up the use of electricity, petrochemicals, medicine and sanitation and now lives with his lovely wife and children in a cave.
His conscience is troubled, however, by his continued affliction with the curses of the lever, the wheel, and fire.

I will no more take responsibility for something that happened hundreds of thousands of years ago than I will for what what my father does today.
I will, however, continue to strive to make the present (and future, by extension) a better place for those that have evolved to this point.
youth in asia:
mmmmm, mammoth steak
You are incorrigible.
;-)
I was going to add something, but I,m feel ing a little hungry at the moment.
@Nearing,
I will no more take responsibility for something that happened hundreds of thousands of years ago than I will for what what my father does today.
Ah ... so then you're saying refusing to revive them is more unethical. We agree ;-)
I will, however, continue to strive to make the present (and future, by extension) a better place for those that have evolved to this point.
I'm a little confused by this. If Neanderthal DNA survived to be reconstituted by the natural process of human intelligence, then that means they evolved to this point - no?
Or otherwise ... since we have the power to drive all other creatures to extinction, does that mean you will not strive to make the present and future a better place for them?
do they taste like chicken?
I admit it im onboard with this.... lets push the technology.
Like I said, Peter:
Just because we can do something, does not mean that we should.
Just because we can do something, does not mean that we should.
Oh, I agree. Also does not mean we should not. My questions are about the distinctions we use to decide this.
I'm old enough to remember the media circus surrounding Dr Barnard's very first heart transplant. Church leaders came out against it - the man's soul will be in danger, science gone mad, etc.
Seems silly today.
I'm old enough to remember the media circus surrounding the first in vitro fertilization of human eggs. Church leaders came out against it - the child's soul will be in danger, science gone mad, etc.
Also seems silly today.
So ... why is it okay for a couple to consensually decide to raise, say, a Downs child, or a Spina Bifida child, knowing all the challenges in front of them, and all the odds stacked against them, but it's not okay for a couple to consensually decide to raise a Neanderthal?
Not saying you're silly - just want to understand your reasoning.
The things I could do with ten million...... there would be lots of happy animal shelters,
If I had a herd of Mammoths I could make a lot more than 10 million dollars.
The Fertilizer sales alone.......
As I tell my kids, "Just because you can do something isn't a good reason to do it!"
:)
someone's been watching too much jurassic park. lol
Scientists could leave well enough alone and contribute that to the auto industry. Jeepers!
Nearing you need to quit! giggle! Good one. Does my 22 lb cat count?
C'mon, who wouldn't gladly hand over $20 for a Woolly Mammoth ride at Sea World? I would. I'd even go up to $10 for a ride on a Neanderthal! Apparently, that would be Ok as long as we didn't get married afterwards...
Shoot, while we're at it, $5 for a ride on Elaine's 22 lb. cat!! We'll have this trillion dollar deficit wiped out in nooooo time.
MAMMOTH GIGGLE! ya'll leave my cat alone. Mr. Pabs is just pleasingly plump. tee hee
I had a large cat that everyone thought was a dog, and I don't think he was 22 lbs! I don't want to cast aspersions, but I've heard from a reliable source that Mr. Pabs is on the juice. Jose Canseco spills the beans in his latest book "Puss & Juice". Sorry, Mr. Pabs, there will be no more Tour de Frances for you.
My daughter calls him my funny looking dog! :) I do wonder what he is doing when I'm away. tee hee I'll have to check that publication out. Ok it's past my bedtime, I'm getting sillier and sillier. giggle
S. Elaine:
Does my 22 lb cat count?
Holy Smokes!!!
What do you feed that beast? And don't even try the whole "He just have an overactive thyroid" bit!"
ROFL!!
Mr. Pabs knows how to score chow!
(we have a saying on the Vine - if there aren't any photos, it is a lie. I am not saying anything, I am just saying)
There was a saying in the 70's from a butter commercial that was trying to prevent margarine from taking over..."It's not nice to meddle with Mother Nature".
But with that being said...let's not ressurect a Mammoth on a small island in Costa Rica where it can hide in the jungle and sneak up on people...let's do it in Nebraska so it can eat corn and if it gets pissy and wants to attack people, folks can see it coming over the horizon like hours before it would ever get to them. Worse case scenario is it attacks South Dakota.
Anyway, with elections over we need something controversial and nerve wracking to fill the voids left by not having low grade media hype.
Worse case scenario is it attacks South Dakota.
Oh Lordy, Red, that was the funniest thing I've read all day. Thank you. I'm still giggling.
Me too, bejeebs!
Belly laugh!
Let's do it. Not only would it be kickass, it would further our knowledge about how to go about resurrecting species. We would no longer need to worry about extinction.
Perhaps it would also revive interest in science in our country...
Um, Insert_, you have to feed them or it's just inhumane....
Feed them? We don't have trouble feeding elephants. Why is feeding them a problem?
actually, that's close red, but, it's "It's not nice to fool with mother nature." I used to love that commercial as a kid. Lol But I agree with you. Let's have Disney make us mechanical mammoths and such to ride, and leave jurassic park to the movies and books. Hey, Palin is still in the states, we still have something to argue about, like where she stashed the rest of her stolen underwear! :-)
Say isnt there a place in the mid-west that has an annual cow flop hurling contest? Just think mammoth flop. BIG TIME . real big time.
Holy Crap!
*grin*
I think that's either texas or nebraska, maybe kansas; lol
it's Oklahoma
Although this is amusing and a great side note to our current state of affairs....
I can't even fathom in wasting the money on a Mammoth resurrection on this already crowded earth.
We aren't even taking care of our pachyderm's that are not extinct yet!
This would be pushing the envelope beyond any humanity of which we are already scraping the bottom of the bowl.
Michelle:

That's right. Tell these Neanderthal posters what's up!
It's inhumane - to say the least.
(all kidding aside, that is)
We homo sapiens are not doing right by the elephants that are in existence now! I mean, can you imagine the Mammoth Ivory Market (for impotence, of course, damn men) that would spring up?
It's nuts to assume we know what's best here.
OMG, do it, do it!! Even just one mammoth and one neanderthal... How crazy cool would that be! Especially the neanderthal. It would be really incredible be able to find out exactly how much like modern humans they were. He or she could be raised more like a human child with a strange medical condition than as a science experiment. Depending on a number of factors, the hypothetical neanderthal could even end up living a relatively normal human existence.
I don't think it'd be any less ethical to bring to life such a neanderthal-person than to carry to term a baby whose medical condition guarantees a lifetime of painful surgeries. I say let's walk on the wild side and make a neanderthal baby if we get the chance.
I read an article not too long ago, that postulated the potential ability of neanderthals actually being able to talk. Cant remember where I read it though, but it was a reputable research effort. Their conclusion through computer simulations was that there was no reason for them to not be able to vocalize even though there are physiological differences.
Hullaballoon,
Please tell me you are being sarcastic.
(BTW, I love your name)
I read an article not too long ago, that postulated the potential ability of neanderthals actually being able to talk.
I can see it now, standing outside the cave....
Neanderthal- "Woman, come here! What is land on other side of water?"
Mrs. Neanderthal- "Oh, that's Russia, you betcha!"
Holy crap, ahahhahahahhhaaa... lol. *snort*
Friending the Bejeebies.
you guys should watch the science channel... they did a show in which the scientists have changed their view of them. they even think when they get the DNA sequenced that some of us are Neanderthal... as in they did not go extinct, they interbred with cro magnon and became us... no longer are they thought to be mute brutes (aka the typical caveman)they had art, tools, language.
I actually was wondering where my ex husband came from.....

Now THAT was funny. As a man and alleged Neanderthal, I should be outraged. Yyyyeah, but no- that was hilarious. Two opposable thumbs up!
i think mother nature has been interfered with long enough...
me too, it's not nice to mess with Mother Nature.......... kinda sceeeeeery!!!!!!!!!!!!! Interesting though.................... That was a cool wooly mammoth in Ice Age.
Uh, this could actually be profitable, guys. Imagine a zoo where you could visit a living wooly mammoth - the place would be more popular than Disney Land. A brother just needs a little start up cash. Heck, I'll throw in a twenty - the more biodiversity the better.
Although, I admit there are ethical issues. It seems a little cruel to resurrect this poor creature and lock it up to be stared at for the entirety of its life.
Just one question: Would they be able to reproduce?
Uh, this could actually be profitable, guys. Imagine a zoo where you could visit a living wooly mammoth
Wasn't there a movie like that?
They should try the experiment on Senator Harry Reid. Maybe it'll work.
no thats bringing the dead back to life ... like frankenstein...
if they won't to bring the dead back to life...how about bringing our founding fathers back to straighten out all the mess we are in...
They would probably prefer to stay where they are.
I think its money better spent than researching nuclear weapons....
hey im on board with the glow in the dark cats...
That would be cool
they should bring it back to lifei thinkit would be nice to experience it
