"A large part of our mammoth timeline is based on the nearly two-year gestation of the calves," Lamm said. But Ben Lamm, Colossal's founder and CEO, noted via email that the Tasmanian tiger's expected gestation period of up to 42 days would be much shorter than that of an elephant-mammoth hybrid. By comparison, Colossal hopes to bring its first woolly mammoth calves into the world within the next five or six years, using elephant surrogates.Ī timeline for the thylacine hasn't been revealed. It could arrive as early as the next few years. The thylacine played that role for thousands of years, Pask said, and its return now could restore balance to the entire ecosystem in Tasmania. The return of an apex predator would "remove the sick and weak animals from the population to control the spread of transmissible diseases and also improve the genetic health of all the populations it impacts," he added.

"The thylacine was the only apex predator in the Tasmanian ecosystem, so no other animal was able to fill its place once it was lost," Pask said. How would the thylacine affect Tasmania's habitat? The altered nucleus would then be inserted into a Dasyurid egg - and when it develops into an embryo, it would be implanted into a surrogate. Its scientists will use CRISPR gene editing technology to splice bits of recovered thylacine DNA into the genome of a Dasyurid - a family of carnivorous marsupials such as the numbat and Tasmanian devil that are the extinct animal's closest relatives. Instead, Colossal plans to essentially create a hybrid animal, with many of the characteristics of a Tasmanian tiger. That process requires a living cell," evolutionary biologist Beth Shapiro of University of California, Santa Cruz told NPR when talk of resurrecting the mammoth gained new currency in 2015. "Cloning is a very specific scientific process.
