I think this is doable. It will take time, however they have an increasing number of frozen mammoths, and even more mammoth tusks (I do not know if the tusk has a 'root' as a tooth does. By sequencing all these sources they have a good shot at crafting the full genome. As a mammal, the closely related species of elephant they have found should be able to provide viable eggs that can be renucleated with mammoth DNA based starters with the correct initiators to render them viable. They have the ability to make the eggs in the lab, fertilize them and see how they progress through numbers of divisions. Once they reach that point, they can try implantation, or even artificial wombs that has been done for mice - will it scale? Their timeline of ~~6 years also seems viable, and it may be faster or slower. Man has caused many extinctions, they say mammoths are one of them - perhaps others we extincted can be saved as well, if suitable source material can be found, such as earlier races of man that might be as good or better than man? I am amazed that the bio establishment does/has not do/done/tried this - leaving it to entrepreneurs?
