In a move straight out of science fiction, Colossal Biosciences, a Dallas-based biotech company, has taken the internet by storm after unveiling three genetically engineered canines designed to resemble the extinct dire wolf. Named Romulus, Remus, and Khaleesi, these pups are part of the company's bold venture into the world of de-extinction.

Using ancient DNA from dire wolves that vanished around 12,000 years ago, Colossal’s scientists employed CRISPR gene-editing technology to alter the DNA of gray wolves. They focused on 20 specific genetic sites, adding traits like a larger skull, stronger build, and distinctive features of the dire wolf. These modified cells were then placed into domestic dog egg cells, resulting in successful births.

But not everyone is howling with excitement.
Many in the scientific community argue that these creatures are not true dire wolves, but rather genetically modified gray wolves. The main concern lies in the fragmented nature of dire wolf DNA and the vast genetic gap between the extinct species and modern canines.
The debate went viral when an Indian man questioned the authenticity of the project on platform X (formerly Twitter). In response, Colossal Biosciences shared their YouTube channel, showcasing the puppies and offering a peek into their growth and behavior.
While the project raises eyebrows, it also opens the door to bigger questions: Should we bring back extinct species? What are the ethical and ecological implications of such actions? And most importantly, are we ready for a world where de-extinction becomes the norm?
Colossal's work represents a groundbreaking step in conservation biology—blurring the lines between extinction and existence. Whether you see it as science gone too far or a hopeful glimpse into the future, one thing’s certain: the dire wolf is back in the spotlight.
