In the last years is born an out of reality idea, re-give life to extint animals.
This can be possible because some scientifics that had won the Nobel, discovered tecniches to get DNA of extint animals from their bones or fossiles and an other scientific teach us how to modificate genetics so we can find an animal in live that has a lot of characteristics in common with the extint one and with the information of the original DNA we can change the genetic of the real animal and when it reproduces the "One time extint animal" come back to world.
This madness is not to far from us, lately the USA Colossal Biosciences has invested more than 200 milion dollars for the project Mammoth and Dodo, this are the two animals that are thinked to revive.
Of course this idea is the origin of a lot of controversial, for example much people ask: "Is this ethically possible?" or "Can we bring back to life animals that are not more part of this planet?
