Bring back the woolly mammoth

Scientists estimate that more than a billion different species of animals and insects have existed. They study extinct species to get a better understanding of past and many of them interested to seeing some of them walk the Earth again

Scientists want to try to revive extinct species like: the woolly mammoth, the mao and the bucardo

They aren't same and they live in different periods but the most important cause of there destruction is human. So it seems somehow fitting that we are thinking of reviving them now

We have two possible method for reviving an extinct species. The first method is growing up sex cells in laboratory. The second method is involves a type of cloning. In cloning, the DNA of one individual replaces the DNA of another

Some scientists believe species revival will never happen and possible because both methods are problematic. And we have a lot of challenges too. How to obtain enough high_quality DNA is one of them

And in these way, individual could never have a normal life and they can't live out of zoo

Savory chocolate....
