  • Mammoths return?

    "If spermatozoa of extinct mammalian species can be retrieved from animal bodies that were kept frozen for millions of years in permafrost, live animals might be restored by injecting them into (eggs) from females of closely related species," the researchers said in a paper appearing in Tuesday's issue of Proceedings of the National Academy of Sciences.

    Descendants of extinct mammals like the giant woolly mammoth might one day walk the Earth again. It isn't exactly Jurassic Park, but Japanese researchers are looking at the possibility of using sperm from frozen animals to inseminate living relatives.

    So far they've succeeded with mice -- some frozen as long as 15 years -- and lead researcher Dr. Atsuo Ogura says he would like to try experiments in larger animals.

    "In this study, the rates of success with sperm from 15 year-frozen bodies were much higher than we expected. So the likelihood of mammoths revival would be higher than we expected before," Ogura said in an interview via e-mail.

    While frozen sperm is commonly used by sperm banks, the team led by Ogura, at Riken Bioresource Center in Ibaraki, Japan, worked with sperm from whole frozen mice and from frozen mouse organs.

    "If spermatozoa of extinct mammalian species can be retrieved from animal bodies that were kept frozen for millions of years in permafrost, live animals might be restored by injecting them into (eggs) from females of closely related species," the researchers said in a paper appearing in Tuesday's issue of Proceedings of the National Academy of Sciences.

    Intact mammoth bodies have been excavated from Siberian permafrost.

    Dr. Robert W. McGaughey, laboratory director at the Institute for Reproductive Studies in Scottsdale, Ariz., commented that since some of the whole frozen mice had been held for 15 years before obtaining the sperm nuclei "it clearly is possible that some day we may be able to obtain offspring from extinct animals frozen at reasonable temperatures for very long periods of time."

    While we allow elephants themselves to slip into extinction?

    I think we need to concentrate on preserving the current species.

          It seems that they're wanting to re-introduce the woolly mammoth.

          Here comes some rotten competition!

            First it will be mammoths, then the Sabre tooth tiger, then a raptor followed by a T-Rex!

            LOL

                PR remind me of the proggy i used to watch as a very young child, i don't remember what it is called anymore.

                premise is 2 siblings (brother and sister who are both half cyborgs) fighting giant dinosaurs in a tank that splits in two and transforms into a jet (with spinning drill infront). later on in the show the jet transforms into a giant robot.

                    they also had two funny guys who would control the 2nd half of the tank when the jet part took off to destroy the dinosaur. the dinos would always explode when killed and they'd always have to drill the sucker to kill it.

                        I think they would be trying to do it just purely for curiousity and science, not to actually reintroduce it into the wild

                          It's just one of those fixed ideas, scientists said that it would be possible to bring back mammoths some 30 years ago and by hell and high water they aint giving up
                          If there's artificial intelligence, there's bound to be some artificial stupidity.

                            Most biologists harbor the hope of being able to 'resurrect' endangered or extinct species, totally ignoring that extinction is a natural process. Yes, it's a guilt thing because some extinctions are human influenced, but they ignore that even those extinctions could allow other species to come foreward.

                              I've been periodically humming the "Jurassic Park" theme since I first read this thread a few days back...

                              I'm the least you could do, oh yeah
                              If only life were as easy as you
                              I would still get screwed
