This photo shows a museum worker inspecting a replica of a woolly mammoth (Mammuthus primigenius), a relative of modern elephants that went extinct 3,000 to 10,000 years ago.
Biologists briefly brought the extinct Pyrenean ibex back to life in 2003 by creating a clone from a frozen tissue sample harvested before the goat's entire population vanished in 2000. The clone survived just seven minutes after birth, but it gave scientists hope that "de-extinction," once a pipedream, could become a reality.
Ten years later, a group of researchers and conservationists gathered …show more content…
in Washington, D.C., for a forum called TEDxDeExtinction, hosted by the National Geographic Society, to talk about how to revive extinct animals, from the Tasmanian tiger and the saber-toothed cat to the woolly mammoth and the North American passenger pigeon. Though scientists don't expect a real-life "Jurassic Park" will ever be on the horizon, a species that died a few tens of thousands of years ago could be resurrected as long as it has enough intact ancient DNA.
Some have their hopes set on the woolly mammoth, a relative of modern elephants that went extinct 3,000 to 10,000 years ago and left behind some extraordinarily well preserved carcasses in Siberian permafrost. Scientists in Russia and South Korea have embarked on an ambitious project to try to create a living specimen using the DNA-storing nucleus of a mammoth cell and an Asian elephant egg — a challenging prospect, as no one has ever been able to harvest eggs from an elephant.
But DNA from extinct species doesn't need to be preserved in Arctic conditions to be useful to scientists — researchers have been able to start putting together the genomes of extinct species from museum specimens that have been sitting on shelves for a century. If de-extinction research has done anything for science, it's forced researchers to look at the quality of the DNA in dead animals, said science journalist Carl Zimmer, whose article on de-extinction featured on the cover of the April issue of National Geographic magazine.
"It's not that good but you can come up with techniques to retrieve it," Zimmer told LiveScience.
For instance, a team that includes Harvard genetics expert George Church is trying to bring back the passenger pigeon — a bird that once filled eastern North America's skies. They have been able to piece together roughly 1 billion letters (Each of four nucleotides that make up DNA has a letter designation) in the bird's genome based on DNA from a 100-year-old taxidermied museum specimen. They hope to incorporate those genes responsible for certain traits into the genome of a common rock pigeon to bring back the passenger pigeon, or at least create something that looks like it.
A few years ago, another group of researchers isolated DNA from a 100-year-old specimen of a young thylacine, also known as Tasmanian tiger. The pup had been preserved in alcohol at Museum Victoria in Melbourne. Its genetic material was inserted into mouse embryos, which proved functional in live mice.
Should We?
Now that de-extinction looms as a possibility, it presents some thorny questions: Should we bring back these species? And what would we do them?
MIKE TAYLOR/CONSERVATION INTERNATIONAL
Gastric brooding frogs come in two species: Rheobatrachus vitellinus and R. silus (pictured above and last seen in 1985). These frogs had a unique mode of reproduction: The female swallowed fertilized eggs, turned its stomach into a uterus.
Stuart Pimm of Duke University argued in an opinion piece in National Geographic that these efforts would be a "colossal waste" if scientists don't know where to put revived species that had been driven off the planet because their habitats became unsafe.
"A resurrected Pyrenean ibex will need a safe home," Pimm wrote. "Those of us who attempt to reintroduce zoo-bred species that have gone extinct in the wild have one question at the top of our list: Where do we put them? Hunters ate this wild goat to extinction. Reintroduce a resurrected ibex to the area where it belongs and it will become the most expensive cabrito ever eaten."
Pimm also worries that de-extinction could create a false impression that science can save endangered species, turning the focus away from conservation. But others argue that bringing back iconic, charismatic creatures could stir support for species preservation.
"Some people feel that watching scientists bring back the great auk and putting it back on a breeding colony would be very inspiring," Zimmer told LiveScience. The great auk was the Northern Hemisphere's version of the penguin. The large flightless birds went extinct in the mid-19th century.
Other species disappeared before scientists had a chance to study their remarkable biological abilities — like the gastric brooding frog, which vanished from Australia in the mid-1980s, likely due to timber harvesting and the chytrid fungus.
"This was not just any frog," Mike Archer, a paleontologist at the University of New South Wales, said during his talk at TEDxDeExtinction, which was broadcast via livestream. These frogs had a unique mode of reproduction: The female swallowed fertilized eggs, turned its stomach into a uterus and gave birth to froglets through the mouth.
"No animal, let alone a frog, has been known to do this – change one organ in the body into another," Archer said. He's using cloning methods to put gastric brooding frog nuclei into eggs of living Australian marsh frogs. Archer announced today that his team has already created early-stage embryos of the extinct species forming hundreds of cells.
"I think we're gonna have this frog hopping glad to be back in the world again," he said.

The 10 smartest animals
How do humans compare to other intelligent creatures? http://www.nbcnews.com 20/08/2012 Sciences * We humans have the ability to learn, to reason and solve problems. We're self-aware, and we're also conscious of the presence, thoughts and feelings of others. We make tools and practice the art of deception. We're creative. We think abstractly. We have language and use it to express complex ideas. All of these are arguably signs of intelligence. Scientists may not agree on the best and fullest definition of intelligence — but they generally agree that humans are highly intelligent. * Chimps are almost like us
-------------------------------------------------
-------------------------------------------------
Tetsuro Matsuzawa / AP
If we humans possess intelligence, chimpanzees must have some as well: Our genomes are at least 98 percent identical.
Chimps make and use tools, hunt in organized groups and engage in acts of violence. Wild troops have distinct behaviors and customs. Field observations and lab experiments show chimps are capable of empathy, altruism and self-awareness. In the experiment pictured here, chimps performed better than humans on a number memory test. * Dolphins get creative
-------------------------------------------------
-------------------------------------------------
Janet Mann / Georgetown University
This dolphin in Australia uses a sponge to protect her snout when foraging on the seafloor, a tool use behavior that is passed on from mother to daughter. Scientists say that's just one sign of dolphin smarts. Other signs include distinct whistles and clicks that may serve as dolphin names, perhaps used in a type of language. A famous 1960s experiment found that a pair of dolphins entered a tizzy of creativity once they figured out their novel behaviors were rewarded with fish. Frustrated human test subjects just let out a sigh of relief when they caught on to the idea.
Elephants exhibit self-awareness
------------------------------------------------- …show more content…
-------------------------------------------------
AP
The sheer size of their brains suggests that elephants must know a thing or two about the ways of the world. They have been seen consoling family members, helping other species in times of need, playing in water and communicating with one another via vibrations sensed in their feet. A crowning achievement, some researchers say, was when this female Asian elephant named Happy recognized herself in the mirror. The complex behavior is shared only with humans, great apes and dolphins. * Cephalopods have big brains
-------------------------------------------------
-------------------------------------------------
Binyamin Hochner
Are octopi, squids and cuttlefish smart? That's a matter of scientific intrigue, but such cephalopods are certainly among the brainiest invertebrates in the sea. The cephalopod brain surrounds the esophagus, but shares with the human brain features of complexity such as folded lobes and distinct regions for processing visual and tactile information. The how-smart debate swirls around deciphering observations that the creatures have a seemingly irrepressible curiosity, a disdain for boredom, an ability to learn and the capacity to use tools. The octopus pictured here exerts precise muscle control to eat. * Crows get crafty
-------------------------------------------------
-------------------------------------------------
Alex Kacelnik et al. / University of Oxford
Crows are crafty critters: They fashion tools from twigs, feathers and other bits of debris to snare food from hard-to-reach places. A crow named Betty, pictured here, uses a straight wire she bent into a hook to retrieve food from a tube. The birds are born with a tool-making ethic, but they hone their craft by watching their elders, a sign of higher intelligence. Ravens, a type of crow, have even been shown to manipulate the outcomes of their social interactions for added protection and more food. * Squirrels can be deceptive
-------------------------------------------------
-------------------------------------------------
Gabriel Bouys / AFP - Getty Images file
Is the squirrel pictured here plotting deception? Perhaps. Researchers recently reported that the rodents put on elaborate shows of deceptive caching to thwart would-be thieves. The behavior increased in a lab experiment after squirrels observed humans stealing their peanuts. The researchers called the finding a sign that squirrels can interpret intentions of others, though it could just be a case of learned behavior. Other studies have shown the critters make three-dimensional maps to recall where they cache their nuts. And squirrels in California will cover their fur in the scent of rattlesnakes to mask their own scent from predators. * Man's best friend
-------------------------------------------------
-------------------------------------------------
University of Vienna
Are dogs intelligent or just really good at basic obedience?
They can learn to sit, lie down and fetch, for example, but can they read their owner's intentions? Research suggests they can at least find food in response to non-verbal cues, a type of understanding that scientists think may be akin to the human ability to understand someone else's point of view. The dog in the experiment pictured here accurately discriminated between photos of dogs and photos of landscapes — an indication the dog was able to form the concept of "dog." * Cats are adaptable
-------------------------------------------------
-------------------------------------------------
Bob Pennell / AP
Like dog owners, some cat owners have trained their pets to sit down, roll over and jump through hoops. Cats learn the tricks by observation and imitation, egged on with positive reinforcement. But training cats is harder than dogs. Does that mean they are less intelligent? Not necessarily. Cat experts say felines are just different. They are solitary animals, motivated by the need to survive. This has allowed them to adapt to a variety of domestic environments for at least 9,500 years - even the hoods of
cars. * Pigs are wise ... and clean
-------------------------------------------------
-------------------------------------------------
Paulo Whitaker / Reuters
Here's the dirt on pigs: They are perhaps the smartest, cleanest domestic animals known - more so than cats and dogs, according to some experts. But pigs don't have sweat glands, so they roll around in the mud to stay cool. A sign of their cleverness came from experiments in the 1990s. Pigs were trained to move a cursor on a video screen with their snouts and used the cursor to distinguish between scribbles they knew and those they were seeing for the first time. They learned the task as quickly as chimpanzees.
Appendix * Summerize:
There are the list of top ten animals smartest in the world, the author gave the first place for chimps, our genomes are at least 98 percent identical, especially chimps performed better than humans on a number memory test. The second is Dolphins, they have signs to communicate each other. Next is Elephants exhibit self-awareness and then Cephalopods, they are certainly among the brainiest invertebrates in the sea. Fifthly, it’s Crows, they fashion tools from twigs, feathers and other bits of debris to snare food from hard-to-reach places. Squirrels can be deceptive very well while the best friend of human- the dog can be taught by us. Like dogs, cats are also a smart animal, they have many benefits for us. And the last position is the pig, it may bring some surprise, but They are perhaps the smartest, cleanest domestic animals known - more so than cats and dogs, according to some experts. * Word Bank:
