De-extinction to revive and restore
Jurassic Park the movie was one of its kind…it made history not only in terms of the money it made but also the concept and the idea of bringing back species long dead was both fascinating and and incredulous. Something similar is being proposed by Dr. Stewart Brand, an environmentalist for four decades Brand is already well known for creating the Whole Earth Catalog, The WELL, the Global Business Network and the Long Now Foundation. Now this evangelist wants to re-create — or “de-extinct” — a few animals that’ve disappeared from the planet.
Imagine if the woolly mammoth and the Sabre tooth that you’ve so loved in ice age, the movie were to walk the face of the earth again. Or imagine the passenger pigeons are brought back from extinction by way of a new Bio-genetic technology.This revolutionary technique has been proposed by Brand and is backed on the basis of a ten year research conducted by a team of Spanish and French scientists who almost brought back an extinct wild goat known as Pyrenean ibex back to life.
The process of De-extinction is based on a very simple premise. DNA samples of the extinct species are located from museums or even from ancient fossils, it is withdrawn and injected into a healthy surrogate who can comfortably give birth to the extinct species. In case of the wild goat, the scientists made 56 attempts to impregnate a present day goat , the de-extinct goat was born , it survived a few minutes and then died due to a severe genetic mutation.
But the process of De-extinction raises a whole lot of moral, ethical and philosophical questions. Do we even want to bring back species that have been extinct ? what is the use of reversing the evolutionary process? will the new species that have been brought back be able to adapt and survive in the new eco system or will they alter it completely? These species which are extinct are gone for a reason- the very basic one is that they failed to survive in the time and the circumstances that they lived in .
Stuart Prim at the Nicholas School of the Environment emphasizes on the impracticalities of de-extinction and why conservation should take precedence. According to him bringing back the species will do more harm than good because along with the species one will have to think of recreating the ecosystem and the environment for them to thrive in and recreating nature is a very complex task.
This focus on de-extinction should be justified only if we a a proper environment to bring back the species and the focus should be more on better conservation as a strategy. The reason that drives the species to be extinct is the continued expansion of humans into their environment. this is the issue that should be tackled first.
