Colossal Biosciences, a biotechnology company, is working on bringing back traits of extinct animals using genetic engineering. Since 2021, they have been studying ancient DNA, focusing on key traits of species like the woolly mammoth and the dodo bird. Recently, their scientists edited seven genes in mouse embryos, resulting in mice with thick, woolly fur. This experiment aimed to understand cold-resistant traits, which helped woolly mammoths survive in the Arctic. While the results were shared online, they have not yet been reviewed by other scientists in a journal. The company hopes to apply this research to Asian elephants, which are closely related to woolly mammoths. However, since Asian elephants are endangered, ethical concerns and strict regulations must be considered before making genetic changes.

Genetic engineering has sparked debates among scientists. Some argue that modifying living species is not the same as bringing back extinct animals. Others believe this technology could help with conservation, farming, and medicine. Scientists highlight that tools like CRISPR have made genetic research more precise and efficient. Colossal’s work has received over $400 million in funding, showing strong interest in this field. Some researchers also suggest these methods could help treat human diseases. While de-extinction remains controversial, gene editing continues to shape the future of biotechnology in many areas.
