Resurrecting the Mighty Mammoth, Cheaply

somanyrobots writes with an interesting followup in the New York Times to the earlier-reported substantial reconstruction of the woolly mammoth genome: "Scientists are talking for the first time about the old idea of resurrecting extinct species as if this staple of science fiction is a realistic possibility, saying that a living mammoth could perhaps be regenerated for as little as $10 million. The same technology could be applied to any other extinct species from which one can obtain hair, horn, hooves, fur or feathers, and which went extinct within the last 60,000 years, the effective age limit for DNA." (The Washington Post article linked from the earlier post was much more skeptical, calling such an attempt "still firmly the domain of science fiction." The New York Times article, while describing the process in similar terms, also calls attention to recent advances in sequencing DNA, as well as recoding DNA for cloning.)

is, from the same story, relegated to second interest, for some reason, the idea of resurrecting a neanderthal, the same way as the woolly mammoth. using chimpanzee as the starting cell lineage rather than human, for ethical considerations of course

but this guy won't be dumb. somebody will have to explain to him he's not the last of his kind... he is the 50,000 year old cloned reconstruction of his kind

weird, lonely, and possible on our lifetime

very cool, very freaky

His post assumes that we wouldn't try to establish a breeding population. If we plan on bringing back an extinct species, what moral obligation do we have to prevent its extinction when the only specimen dies? Or is it okay, since our world has moved on since the last mammoth lived? If scientists make one, should we make more and restore a population? Would today's world be a good environment for a wild population or not? Would our creations be forever destined to live in zoos?

If we create a breeding population, how do we ensure genetic diversity? I am not a bioengineer, and have no way of knowing if diversity is already included in their method (taking a living elephant's skin cell and slowly reshuffling the DNA from elephant to mammoth) by simply using cells from different donor elephants for making each new mammoth. I guess that would depend on how reshuffled the DNA gets in the process of injecting new sequences.
