A Possible Breakthrough in Reviving Extinct Species
My first choice is the dodo bird, although they did specifiy mammals here. Look through your freezers, please, for any freezer-burned meat you may have forgotten.
"Researchers at the Riken Center for Developmental Biology in Kobe, Japan, used cells from mice that had been frozen for 16 years at -20 Celsius (-4 degrees Fahrenheit).
They extracted the nucleus and injected it into eggs whose DNA had been removed. Several steps later, the scientists were able to clone the mice.
'This is the first time a mammal has been cloned from a sample stored at conditions reasonably close to what might be expected in permafrost,' Teruhiko Wakayama, who led the study, said in a statement.
'(It) gives some hope for those who might seek to clone extinct species from frozen carcasses.'" [CNN]
