UNIVERSE OF NATURE

For centuries, extinction has been an absolute, irreversible boundary. When the last individual of a species dies, its genetic story ends forever. However, the biotechnology company Colossal Biosciences claims it is about to shatter this fundamental law of nature. With headlines proclaiming a massive leap forward in cellular engineering—specifically, the creation of functional artificial egg cells (oocytes)—the company suggests that the resurrection of lost species like the woolly mammoth, the thylacine, and the dodo is no longer a matter of science fiction, but a looming reality. Yet, beneath the polished corporate presentations and high-production press releases lies a deeply divided scientific community. While some view this as a monumental triumph for genetic rescue, other leading geneticists and conservation biologists urge caution, warning that the public is being sold a brilliant marketing campaign rather than viable science. To understand the true magnitude of what Colossal B...
