From woolly mammoths to saber-tooth cats, to passenger pigeons and dodos, to a myriad of insects and invertebrates, many species have become extinct over time. New scientific advancements are leading to unprecedented uses of fossilized materials. Could these archaeological discoveries combined with scientific breakthroughs lead to the long awaited, long speculated, realization of de-extinction? De-extinction, also called resurrection biology, is the process of resurrecting species that have died out, or gone extinct. De-extinction uses techniques such as cloning to revive an extinct species. De-extinction is a controversial proposition that has split scientists.
Technology to revive extinct species is close to being perfected, but does this mean that it should actually be used? Where will these revived species be housed and what impact will they have on an already changed habitat? What are the ethical pros and cons of reintroducing extinct animals? What limits should be placed on the use of such technology? Should scientists use this to undo environmental harm that has occurred? How might these restored species affect our current biosphere? How might living among de-extinct species affect humanity?
