Extinct frog being brought back

This is the coolest thing I've seen in awhile. Australian scientists have taken the DNA from a frozen specimen of a recently extinct and very unique frog and are using it in donor eggs to revive the species.

Australian scientists have successfully taken the first steps necessary for bringing back an extinct frog species.

The team, led by University of New South Wales paleontologist Mike Archer, has grown embryos with the revived DNA of the extinct gastric-brooding frog for the first time.

The gastric-brooding frogs were a genus of ground-dwelling frogs that were native to Queensland in eastern Australia. It was quite an extraordinary genus because it had the only two known frog species that incubated their offspring in the stomach.

However, the gastric-brooding frog became extinct in 1983.

Now, the research team has brought their DNA back to life. It did this by reviving frozen DNA samples of a gastric-brooding frog and inserting the genetic material into donor eggs. The donor eggs were those of a distant relative -- the great barred frog. But the great barred frog's DNA was deactivated by UV light.

As time went on, the cells began dividing, showing signs of growing embryos.

The embryos have not yet turned into tadpoles, but research shows that the dividing cells do, in fact, have the DNA of the extinct frog.

"We do expect to get this guy hopping again," Archer said.

While finding viable DNA and creating the frog embryos was no easy task, this opens the door to the possibility of bringing other extinct species back to life.

Here's hoping that enough preserved specimens with viable DNA can be found to recreate the species.

Cool stuff! They're also working on other species (passenger pigeon, European aurochs, Pyrenean ibex, American chestnut, Tasmanian tiger, California condor, and woolly mammoth)

I'm still holding out hopes for velociraptors.... (even though they might not have existed but that's another discussion.....)

Anyway, cool story :thumbsup:

We have the technology to do some really great things. When you have stem cell research that can regrow body parts or organs and the ability to bring back an extinct species, it really makes you wonder where things will be in 100yrs. Of course thats if no one stands in our way (government or religion).

Without native habitat, what the point?

WE WANT DODO'S! WE WANT DODO'S! WE WANT DODO'S!
Big tasty Dodo's!

Most have plenty of habitat in which to exist, why would you oppose it?

 

[spittledip]

This is really exciting news! I hope it goes through successfully.

Here is a link to candidates for revival from the link PC Surgeon shared:

What is your understanding of species extinction? Bad luck?

Loss of habitat is responsible for "most" species extinction. But go ahead, I'd love to hear your take on the subject. Its bound to be hilarious.

hmmmm.. this is pretty cool. I remember scientists bringing an extinct flower from the age of the dinosaurs back to life.. I need to see if I can find that article. Maybe this is a sign of reviving extinct species? One can only hope..

Of the species I named, only the passenger pigeon would be lacking in available habitat. Go fuck yourself loser boy.

they should make a B-move Giant Carnivorous Frog vs Big Ass Spider.

You can do better than that...although I don't hold out much hope.

Lets try again:

Thats really cool. I hope they bring back the dodo bird and wooly mammoths too. Sabertooth tigers and dinosaurs would be amazing also.

Maybe they can bring back some real politicians to replace most of the ones we have now!

Pretty damn good you dumbshit. The OP is about a particular frog and my post named specific species that scientists are working on bringing back from extinction. It has nothing to do with species that are failing due to any number of factors, but feel free to get on a soapbox and lecture us all.

This was uncalled for.

Still waiting to hear your understanding of species extinction.

At least in case of most extinct Australian species, introduced foreign competitors is the major cause. Should we be able to find enough distinct specimens to recreate a viable population, available habitat would certainly not be a problem in maintaining a very small frog. If nothing else, zoos around the world could maintain ark populations.

In other cases such as dodos or passenger pigeons or Thylacines, human action reduced the populations to zero or at least to below viable levels. Given smarter humans and adequate government protections, this should not be a problem again.

Maybe they can bring back some real politicians to replace most of the ones we have now!

Ladies and gentlemen, I present our Republican candidate, Thomas Jefferson 2.0A, who is clearly much more ethical, smarter and better looking than the dastardly Democrat candidate, Thomas Jefferson 2.0B.

LOL I'd watch that. In fact, it's probably already been made for the SyFi channel, albeit with a $50,000 budget.

species die for a reason, and even if it is directly humans fault we are not going anywhere. if anything, only bring back species that have died in the last 100 years because those probably could be accounted for human stupidity. sadly though, it wont have an environmental impact because they all would likely be kept in zoo's.

but really, what theyre doing is playing god. if pro-life activists stand outside in the rain all night holding graphic images of dead babies due to the fact it wasn't god's choice, they should be just as upset that humans also create life too.

Oh noes! I was hoping to see the mass extinction caused by global warming meme.

Um, pretty sure pro-life activists are standing out in the rain because babies are being killed, not because it isn't G-d's choice. As far as humans, it's true we aren't going anywhere, but we have changed. Simple government protection would likely be enough to save a resurrected Carolina parakeet that was clearly made extinct by human action. For other species such as ivory-billed woodpeckers reestablishment would clearly be much more difficult, but hardly impossible. Paper companies have a huge amount of land compared to the demand for paper, which is decreasing. Same with the demand for hardwood. I think it might well be more profitable for these companies to either hold this land in a conservation trust (funded with tax money) or simply sell to the federal government - IF we can establish the species that need this kind of very large, relatively unbroken mature woodland. With other, smaller species such as Carolina parakeets or gastric brooding frogs or whitestripe topminnows, it's possible that a combination of arc populations and pet trade could preserve the species if nothing else.

And I don't think it's playing G-d if we're trying to fix our own mistakes.
