In April Time magazine published a story entitled The Return of The Dire Wolf. Having roamed America's continent for thousands of years, the dire wolf had gone extinct around 10,000 years ago. Until, that is, a company called Colossal Biosciences claims that it has managed to bring the species back to life in the form of two wolf pups: Romulus and Remus.

But despite the scientific wonders of gene editing, can we be sure that these pups are genetically identical to the dire wolfs of the past? Are genetics all that matters in the identity of a species? And even if it is practically possible to bring back to life species that have gone extinct - is it a good idea? Are we are morally obliged to bring lost species back to life if we can, especially if humans were responsible in their extinction? Or would such a practices risk "Jurasic Park"-like scenarios and our limited resources for environmental conservation are best channelled in preserving existing species?

Jay Odenbaugh is the James F. Miller Professor of Humanities at Lewis & Clark College in Portland, USA. His research is in the philosophy of science, especially ecology and conservation biology, and environmental philosophy. He is the author of the book Ecological Models (Cambridge University Press) and has written about the ethics and aesthetics of species conservation and de-extinction.
