Some de-extinction advocates have also positioned their projects as potential long-term solutions to combating mass biodiversity loss in general.īut many ecologists and ethicists have highlighted the uncertainty around introducing these novel creatures into the wild. “Bringing back” passenger pigeons could help restore forests in the northeastern United States, for example, while woolly mammoth proxies could help restore the Siberian steppe and keep permafrost frozen. Supporters have argued that de-extinction will eventually help restore ecosystems. They’re certainly amassing a fortune to make it happen: Since its founding in 2021, Colossal has raised over $225 million from tech investors, Paris Hilton and even a CIA-backed venture capital firm. And yet Colossal seems confident, saying it hopes to de-extinct Tasmanian tigers by 2025 and woolly mammoths by 2027. Nor have any other scientists, unless you count the team that cloned the Pyrenean ibex in 2003 - but that clone died within minutes. Tambako the Jaguar/Moment via Getty ImagesĬolossal hasn’t successfully created any de-extinct creatures yet. A Nicobar pigeon, the dodo’s closest – and much more colorful – relative. Nor would it have any other dodos to teach it how to act like and, well, actually be a dodo. Then they could put that genome into an egg cell, and let that egg develop into an organism that should look like a dodo.īut that organism wouldn’t be genetically identical to the dodo. Scientists would edit the genomes of the dodo’s closest living relative – the Nicobar pigeon, which contains the pigeon’s full set of DNA – and add some of the most important dodo genes, taken from preserved dodo remains. Rather than “bringing back” lost species, it’s more of a process to create their high-tech look-alikes. What de-extinction is and isn’tĭe-extinction is not exactly what it sounds like. One of us, Ben, is a professor of environmental ethics who explores the ethics of de-extinction in his 2018 book “ The Fall of the Wild.” The other, Risa, is a doctoral student researching how de-extinction might change public perceptions about extinction, especially its emotional impact. The company says its goal is to create a population of undead dodos to put on the Indian Ocean island of Mauritius, where the hefty, flightless creatures lived before humans drove them to extinction in the late 1600s.Īs environmental humanists, we study the morality of different conservation interventions, and are interested in how de-extinction might change the ways people think about their responsibilities toward nature. You can listen to more articles from The Conversation, narrated by Noa, here.Ĭolossal, a biotechnology company that garnered headlines for its plan to “de-extinct” the woolly mammoth, is now attempting to “bring back” the famously dead dodo bird. What can scientists possibly do to stop that trend? For some, the answer is to “de-extinct.” ![]() An estimated quarter of all species on Earth are at risk of being lost, many within decades. Extinctions are happening at a dramatically faster rate than they have over the past tens of millions of years. It’s no secret that human activities have put many of this planet’s inhabitants in danger.
