- Scientists in Tibet are cloning yaks to create an 'elite' herd of super-yaks with better health and fertility.
- The first yak clone was born in July 2025, with 10 more born by spring, and a goal of 100 clones by 2028.
- Both domestic and wild yaks face threats from climate change, habitat degradation, inbreeding, and cross-breeding.
- Cloning involves transferring nuclei from donor cells into enucleated eggs, then implanting into surrogate mothers.
- Researchers aim to apply cloning to conserve endangered wild yaks, including the rare golden wild yak with only 300 individuals left.
- The project has raised ethical concerns about transparency, animal welfare, and potential ecological impact.
- Supporters argue cloning could boost the yak industry and help conservation, while critics warn of unintended consequences and 'playing God'.
