Reviving an extinct species is no longer a fantasy, but the question is how do scientists plan to do it? This question can be answered in simple words, it is a new revolutionary method known as resurrection biology or also species revivalism. In this process of generating an organism that is extinct, it could be accomplished by cloning. Though this method is now being used only for certain endangered species, in hope to boost populations. Cloning is a method for the potential restoration of an extinct species. This of course can be accomplished by extracting the nucleus from a well preserved cell from the extinct species that is not that far extinct and swapping it into an egg. The egg then is inserted into a host from the nearest living relative. This method has been widely used, starting in the 1950’s with Dolly, the sheep. Among the animals that could be exposed for de-extinction are mammoths, saber toothed tigers, and even dodos.
