Part 2/7:
De-extinction refers to the process of resurrecting extinct species through modern genetic engineering techniques. Traditionally, extinction has been considered final; however, advances in DNA sequencing and gene editing are challenging this notion. Colossal Biosciences is at the forefront of this movement, aiming to use CRISPR technology—a powerful gene-editing tool—to reintroduce DNA from ancient samples into living relatives, thereby creating organisms that resemble their extinct ancestors.
