I guess the reasoning behind this is to foster the abilities in genetic engineering.
Did those scientists never read jurassic park?
Not that bringing back the dodo bird or mammoths would have quite the same effect probably but species go extinct for a reason.
In a lot of cases, the reason is that they were driven to extinction by humans.
Betteridge’s law.
In this case, while it might be possible to reproduce a member of an extinct species, if the conditions which cause the die-off of that species are unchanged then the species will still be extinct. The living individual would be a curiosity at best.
Where are these mammoths meant to roam ? And does anybody get why they think trampling grass and snow is going to protect permafrost ?
My problem with private companies doing this, is that, it will probably end up like the cryogenic fad.
