Using DNA from an extinct species To make "life" today?

[dibbers]

So we all know of the sheep that was cloned, mice and all the other things that they haven't told us, so what about a "human" ? I know it's very taboo and the like, but I bet they have done it.....

We all know that it's possible, so what's stopping us using the dna from a species that is totally extinct, call it a late post and some thing to sleep on, but what and why could it be or not be done?

We take some primate's dna for example and get the building blocks of life and then implant it into a female to give birth to a whole species of life that is (was) extinct? would that make them "not" ?

Suppose you took a Neanderthals dna and create a embryo and implant it into a female we have a child with the DNA of about 200,000 years ago? what would be the outcome?

Suppose we done it with birds that are extinct, like the "dodo" of course not "cross species" so maybe plant that in a goose and see what happens when the eggs hatch, I presume the "dodo" laid eggs? lol....and I have no idea of how big they are as I've never seen one....oc:

But back to a "human" a "person" a living thing, with a soul and a heart, feelings, you know a real live person, just with the dna from 200 thousand years ago?

.....what would he/she be like? would they grow up totally intelligent if brought up in an environment that offered that, you know uni etc.

Suppose you made a colony of them on an island some where, where they could populate, could you bring back an entire wiped out human species...?

I don't know mate... next thing we'll have an island somewhere you can visit like a wildlife park and see dinosaurs and such roaming - na, that's a stupid idea

apologies to Michael Crichton memory for mocking

 

[neorage]

is this the plot to "immigrant park"... hmmm

not offence was intended by the above remark, just couldnt think of a better word to use

To paraphrase, because we can, doesnt mean we should...

That's the 1st boring post I've seen you make....lol! just thinking of the why and what not's and that of it all...just found it interesting...

 

[**override**]

I think some of DW members have been extracted from something lol

.....I suppose some of even the greatest philosophers back in the day got mocked, ha! where would we be with out them!

Oh Bugger, must have been summat I ate...

...just discussing the line with Jeff, will try harder

There was talk about cloning and bringing back to life a mammoth, what's next a sloth, a Smilodon perhaps??? lol Maybe the funding is coming from Hollywood, they want to redo the movie Ice Age lol

Personally yeah I think, they've done a human, but that would be all hush hush. The worlds over populated as it is, and i don't think normal human beings would accept it. WATCH the Movie The 6th Day. I wonder were they get ideas from?!?!

 

[cmangle]

hmmm, get the dna from that antartica rock and grow a extinct martian? nahhhh

they did try the mammoth but it died BBC News - Russian scientists to attempt clone of woolly mammoth

Russian scientists to attempt clone of woolly mammoth A clone could be attempted using bone marrow cells Continue reading the main story

Scientists from Russia and Japan are undertaking a Jurassic Park-style experiment in an effort to bring the woolly mammoth out of extinction.

The scientists claim that a thigh bone found in August contains remarkably well-preserved marrow cells, which could form the starting point of the experiment.

The team claim that the cloning could be complete within the next five years.

But others have cast doubt on whether such a thing is possible.

Mother cow?

The team, from the Siberian mammoth museum and Japan's Kinki University, said that they planned to extract a nucleus from the animal's bone marrow and insert it into the egg of an African elephant.

Similar procedures have been done before with mixed results.

In 2009 it was reported that the recently extinct Pyrenean ibex was brought back to life briefly using 10-year-old DNA from the animal's skin. The cloned ibex died within minutes of being born, due to breathing difficulties.

The Roslin Institute, famous for cloning Dolly the sheep, no longer conducts cloning work but has published some thoughts on the possibilities of bringing extinct species back to life.

It said it was extremely unlikely such an experiment would be successful, especially using an elephant surrogate.

"First, a suitable surrogate mother animal is required. For the mammoth this would need to be a cow (as best biological fit) but even here the size difference may preclude gestation to term," it said.

The success rate for such an experiment would be in the range of 1-5%, it said.

The second issue would be the need for viable whole cells.

"If there are intact cells in this tissue they have been 'stored' frozen. However, if we think back to what actually happened to the animal - it died, even if from the cold, the cells in the body would have taken some time to freeze. This time lag would allow for breakdown of the cells, which normally happens when any animal dies. Then the carcass would freeze. So it is unlikely that the cells would be viable," it said.

Assuming that viable cells are found it becomes a numbers game, it went on.

"Let's say that one in a thousand cells were nevertheless viable, practical issues come into play. Given that we have an efficiency of 1% cloning for livestock species and if only one in a thousand cells are viable then around 100,000 cells would need to be transferred," it said.

Hybrid

Charles Foster, a fellow at Green Templeton College, Oxford, seemed more optimistic.

"The idea of mammoth cloning isn't completely ridiculous.

"How the resultant embryos would fare beyond the stage of a few cells is more or less unknown," he said.

While most of the genetic coding of the embryo would come from the mammoth, some would come from the elephant ovum.

"We really don't know what the contribution of that cytoplasmic material is, or how it would interact with 'alien' DNA," he said.

It would however mean that, even if successful, the clone would be a hybrid rather than a pure mammoth.
