Genesis and birth

Maya was cloned in a Beijing lab using skin cells from a 16-year-old female donor arctic wolf, also named Maya, that was living in Harbin Polarland, an arctic theme-park in China. A skin cell from the donor wolf was inserted into the enucleated

. This method was performed in order to construct 137 new embryos. Scientists then inserted 85 of the embryos into seven different beagle surrogate mothers. The experiments resulted in failed births six out of seven times, with Maya being the only wolf born successfully. Although she was born on 10 June 2022, researchers decided to wait 100 days before unveiling her to the public due to the high likelihood that she would die young. Researchers said that it would be impossible to release her into the wild due to her lack of socialization with other wolves for the beginning of her life. She was then moved to Harbin Polarland where she now lives with her beagle surrogate mother.

Implications for conservation

Although arctic wolves are not under threat, the researchers behind Maya hope that the genetic technology used can potentially help other species under threat as the world heads into an extinction crisis. Sinogene, the company behind Maya, said that it will be working with the Beijing Wildlife Park to research more applications for the cloning of rare and endangered animals in China.
