Until we figure out how to meet the physical and psychological needs of elephants in captivity, they shouldn’t be in captivity at all, much less being used to make mammoths. If we were to put that all aside, I don’t want to see mammoths come back — it’s never going to be possible to create a species that is 100 percent identical. But what if we could use this technology not to bring back mammoths but to save elephants?
What if we could use this technology to make elephants slightly better adapted to cooler climates, the type of place that mammoths used to live? We could then create more space for them. … Mammoths and elephants have approximately 99 percent identical genomes. If we are talking about changing a few genes here and there to make them better adapted to living in the cold, I think we are talking about preserving elephants.
I think that the key use of this technology … is to protect species and populations that are alive today. Take, for example, the black-footed ferrets that are living across the plains of North America. Black footed ferrets nearly went extinct a couple decades ago because of extermination programs. Today, black-footed ferrets are threatened by a disease. What if we could use this same technology that we’re talking about to go back in time, to sequence DNA of ferrets in museums somewhere that are decades or centuries or even thousands of years old, and find genetic diversity in those that we could then inject in the populations today that have no genetic diversity?
Maybe we could use this technology to give those populations a little bit of a genetic booster shot and maybe a fighting a chance against the diseases that are killing them. We’re facing a crisis — a conservation, biodiversity crisis. This technology might be a very powerful new weapon in our arsenal against what’s going on today. I don’t think we should dismiss it out of fear.
