The biologist George Church unearthing woolly mammoth remains in Siberia. A team of scientists and entrepreneurs announced on Monday that they have started a new company to genetically resurrect the woolly mammoth. The company, named Colossal, aims to place thousands of these magnificent beasts back on the Siberian tundra, thousands of years after they went extinct.

George Church, a biologist at Harvard Medical School, who for eight years has been leading a small team of moonlighting researchers developing the tools for reviving mammoths. It’s going to make all the difference in the world. 15 million in initial funding, will support research in Dr. Church’s lab and carry out experiments in labs of their own in Boston and Dallas. Church’s lab, Eriona Hysolli, will oversee the new company’s efforts to edit elephant DNA, adding genes for mammoth traits like dense hair and thick fat for withstanding cold. The researchers hope to produce embryos of these mammoth-like elephants in a few years, and ultimately produce entire populations of the animals.

Other researchers are deeply skeptical that Colossal will pull off such a feat. And if Colossal does manage to produce baby mammoth-like elephants, the company will face serious ethical questions. Is it humane to produce an animal whose biology we know so little about? Who gets to decide whether they can be set loose, potentially to change the ecosystems of tundras in profound ways? An illustration of a woolly mammoth, a species that lived in the Arctic and died out at the end of the Pleistocene. The idea behind Colossal first emerged into public view in 2013, when Dr.

Church sketched it out in a talk at the National Geographic Society. At the time, researchers were learning how to reconstruct the genomes of extinct species based on fragments of DNA retrieved from fossils. It became possible to pinpoint the genetic differences that set ancient species apart from their modern cousins, and to begin to figure out how those differences in DNA produced differences in their bodies. Church, who is best known for inventing ways of reading and editing DNA, wondered if he could effectively revive an extinct species by rewriting the genes of a living relative. Because Asian elephants and mammoths share a common ancestor that lived about six million years ago, Dr.
