But for a species to survive once it's brought back to life, it must have enough genetic variability to reproduce. "A population needs to be adaptive," says Johan van Arendonk, a professor of animal-breeding and genetics at Wageningen University in the Netherlands, adding that the Dutch project probably needs to produce at least 100 animals to succeed in the long term...
...obstacle. Recreating the aurochs from modern cattle won't work if any of its DNA was lost as breeds split apart, experts say. And it will take a lot of time. "The only way we can make recombinations is by having the animals produce a new generation," says van Arendonk. "It's still a very open question if it all can be done...
