Resumen de Extinct is not forever
Cutting-edge biotechnology, including genome sequencing, cloning and gene-editing tools like CRISPR, is allowing scientists to manipulate life.

Even de-extinction's greatest advocates admit that it is expensive and risky, so the reasons for pursuing it need to be well thought out.
